Most diamond core bit manufacturers now ensure that their product is competitive in the market without compromising quality.

Asides from the purchasing cost of a machine or tool, the cost of maintenance informs the final decision. You must strike a balance between these two concepts before embarking on buying any product. The cost of purchasing a diamond core bit must correspond to the value used will derive. It means that cost should be proportional to utility in all cases. The maintenance cost would also come into play once you can overcome the aspect of the purchasing price.

For every tool, machine, or equipment, you know that maintaining it is a necessity. Effective maintenance helps to keep the diamond core bit running at all times. So many factors contribute to how maintenance costs vary for different diamond core bit manufacturers.

Factors that affect the maintenance cost ranges from:

The design of the tool

The material it cuts

The mode of cutting (dry or wet cutting)

The material it is made of and so many more.

In all, you must take into cognizance these many factors to enable you to decide on which brand to go for accurately. So, therefore, make sure you do conduct well-grounded research to be certain of useful facts and figures. While some diamond core bit manufacturers produce high-end bits, some others produce mid-range bits.

3.Durability and Ease of Use

It is essential to look out these qualities when choosing a diamond core bit manufacturer. However, there seems to be a clear difference between them. Durability refers to the degree of how long a tool or equipment last in active service. Ease of use places emphasis on how convenient and effortless it feels when operating by end-users. It is no gainsaying that some brands have invested heavily in getting it right from the very beginning. These go on to become the first-choice diamond core bit manufacturer over time.

A well-established fact is that the durability of a diamond core bit is inherent in its design. Manufacturers have developed a unique approach to design, which will tell on the useful service life of the diamond core bit. After successfully designing the diamond core bit, the next thing is to produce it. Adopting the right metal treatment and finishing process will later go a long way to tell on durability.

Ease of use ensures that new users can successfully use the diamond core bit with little or no supervision by a professional. This concept also determines how the product delivers to get the most with minimal stress. It further relates to how the manner of using the diamond core bit relates to its performance. A significant example here is the issue of wet-cutting and dry-cutting. Recently, a universal diamond core bit has come on sales, i.e., they suit either dry-cutting or wet-cutting.

In essence, do well to be on the lookout for these two characteristics when selecting a diamond core bit manufacturer.

4.Long-standing reputation

Regardless of the industry, the reputation of a product or firm speaks louder for them. Even in situations beyond them, people can attest to their status. Help yourself make the right decision by reading online reviews about a diamond core bit manufacturer.

Endeavour to this before entering into a partnership as a supplier. It will save you the stress of your buyers’ incessant complaints should, in case the brand is terrible. A diamond core bit manufacturer that is known for quality and cost-effectiveness has an imposing reputation. The other tips shared above must also be evident in a typical diamond core bit manufacturer. The diamond core bit manufacturer should have an excellent product, but their added-services should also be top-notch. Value-added services attract and keep credible customers for any firm.

Services such as after-sales services, free consultation, regular checkups, etc. remain an integral part of any reputable business. Again, bear this in mind when selecting your preferred diamond core bit manufacturer.

5.Ease of access to product

Yet again, you must keep this at the back of your mind at all times. When you have satisfactorily treated the other factors above, then the “ease of access to product” must come into play. As an end-user, especially, you have to ensure you purchase a product that is common to your locality. Failure to do these will lead to many unforeseen outcomes. For instance, when buying the diamond core bit, you should first check with stores within your locality. As a major supplier, you do not want to incur the high cost of transporting and logistics when taking delivery of your order. It would, therefore, guide your decision rightly.

Away from the cost of delivery, time to wait for delivery of bulk order also plays a significant part. You would want to reduce the cost incurred and delivery time to the barest minimum. A diamond core bit manufacturer closest to you should be the default preference for you. However, there are rare cases of this not being the norm. Other factors could make you choose a farther away diamond core bit manufacturer if the product meets your need.

6.Overall technical specification

Technical specifications here go beyond just the ability to cut. It cuts across core areas that many diamond core bit manufacturers have distinguished themselves. Diamond core bit may generally perform the same function, but surely in different ways. This ability is always an intrinsic function of their unique design. These specifications will go on to affect the overall performance of the product. The accuracy, the speed it can rotate at, the purpose it can fulfil (wet, dry, or general-purpose cutting). Other specifications, such as length/depth, diameter, teeth design, also vary from one manufacturer to another. While some diamond core bit manufacturers make their product attachable to an angle grinder, others allow attachment to drill.

In a bid to ensure proper and quick disposal of chips, ejector holes come on the diamond core bit. Above all, do not fail to assess all the possible suitable technical specifications of interest to you.

6 Tips for Selecting Concrete Grinding Wheel For Angle Grinder

A metal grinding wheel in action

Concrete grinding wheel for angle grinder is an indispensable tool for a mason that constantly deals with concrete. However, you should know that the angle grinder is only one part of the equation as you have to select the right concrete grinding wheel for angle grinder. Choosing the right grinding wheel is essential for the effective operation of your angle grinder. Consequently, we’ve taken the initiative to list some tips that you will find quite helpful when selecting the right grinding wheel for concrete.

A metal grinding wheel in action
Figure 1 – A metal grinding wheel in action

1.Know the Abrasive Components: Grits or Grains?

Concrete grinding wheels, as well as other abrasive tools, comprise two major components – the abrasive grains that do the cutting and the bond that holds the grains in place while they cut. The percentages of grain and bond plus spacing in the wheel determine its structure. The nature of the abrasive also decides the kind of materials the wheel will be able to cut. Each abrasive type is distinct from its unique properties, such as – strength, toughness, hardness, and resistance to impact.

Aluminium oxide happens to be the very common abrasive manufacturers use in making grinding wheels. This abrasive works well for hard materials such as carbon steel, concrete, high-speed steel, alloy steel, wrought iron, and the like. Understand that there are different types of aluminium oxide abrasives; each of these abrasives comes with its designation. Plus, you can use them for different cutting and grinding operations.

Once you’ve established the grain texture, you should look at the grit size. The grit size is the size of individual abrasive grains in the wheel. Coarser grains allow for the rapid removal of material, plus you can use them when the finish isn’t important. Coarser grains come in small sizes – 10, 15, 25, while higher numbers such as – 70, 100, and 180 are fine-grit wheels. They are quite suitable for fine finishes.

2.Consider the bond strength.

If you want the abrasives on your concrete grinding wheel to cut efficiently, then the wheel must contain the proper bond. The bond is the material that holds the abrasives in place to enable them to cut more effectively. The bond should also wear alongside the abrasive grains, as it will expose sharper grains. Primarily, there are three types of bonds for concrete grinding wheels. Each of these bonds gives distinct characteristics to the grinding/cutting action of the wheel.

Before you select any bond for your concrete grinding wheel, you should consider factors like operating speed of the wheel, the grinding operation, the right precision, and the material in question. Most grinding wheels come with vitrified bonds, which are very porous, strong, and rigid. The remove stock materials rapidly, and they grind to precise requirements. On the good side, they are resilient to water, oils, acid as well as harsh temperatures.

3.Determine the shape of the wheel

Concrete grinding wheels come in a variety of shapes. Most of us probably think that grinding wheels come in one straight shape, but it’s not true. As with other factors, you should also consider the shape of the wheel when selecting a concrete grinding wheel for angle grinder.

On some wheels, you will find the cutting face on the side of the wheel. These wheels usually take the names of their shapes, such as – cup wheels, cylinder wheels, and dish wheels. In some cases, manufacturers fuse-bond abrasive sections of a variety of shapes to form an intermittent continuous side grinding wheel. Wheels with cutting faces on both sides are best for grinding the teeth of grinding tools and other hard-to-reach surfaces. These considerations should come into play when you’re selecting a grinding wheel for concrete.

Wheel diameter is an important factor to consider when selecting a concrete grinding wheel for angle grinder. Angle grinders with bigger wheels tend to be more powerful.

4.Identify the grade of the grinding wheel.

You can find out the strength of a bond in the grade of the grinding wheel. You can tell if a bond is hard if the spans between each abrasive grains are resilient and hold the grains well against the grinding forces that try to loosen them. You can also tell a soft-grade bond if minimal force is all it takes to release the grains. The relative amount of bond in a wheel determines its hardness.

Hard grade wheels allow for longer wheel life, and for jobs that require high horsepower machines. You can also use them for jobs with narrow or small areas of contact. Soft-grade wheels are best for rapid stock removal, for jobs with a large or wide area of contact and materials such as carbides, steel, and concrete.

5.Determine the finish you’re looking to have

The amount of stock you’re looking to remove is also a critical consideration, as this plays a massive role in the finish. Coarser grits will do well rapid stock removal since they are capable of heavier cuts and greater penetration. However, if you’re looking to have a nice finish, then you’ll need a finer grit wheel for your grinding operations. You also need to pay critical attention to the horsepower of the angle grinder as a high RPM can exert a tremendous that may allow for the rapid removal of the material.

The finishing you’re looking to have should also influence your choice of wheel shape as this is crucial as well. In this regard, you should invest more in soft-grade wheels as they require minimal RPM to expose the abrasive grains. It allows you to regulate the horsepower.

6.Consider the wattage of your angle grinder.

The wattage is quite important as it will feed the grinding wheel with the power to cut or grind the material in question. Speed is also of immense essence here; you will need an angle grinder that can match your work speed, which is also congruent to having a high wattage tool.

If you’re looking to cut hard materials like concrete and the likes, then you should go for a material with high wattage, as this will also allow you to use your angle grinder for a long time.

These wheels are distinct for specific purposes. Depending on your operation, cutting, polishing, or grinding, you will undoubtedly find a grinding wheel that suits your needs. There are also wheels with coarse grits and those with super fine grits. However, your job-kind should influence your choice of a concrete grinding wheel.

Can I use a concrete grinding wheel on other materials?

Well, concrete is a hard material, and this sole fact allows concrete grinding wheels to work well for other hard materials. Yes, you can use your concrete angle grinder to cut or grind other hard materials. However, if you must do this, you have to do so with a diamond concrete grinding wheel as diamond grinding wheels are sturdy tools that have proven to be quite resilient.

Are you a beginner when it comes to using a slitting saw? This tool is powerful and versatile, but it also requires knowledge to use its fullest potential. Among other things, you should get familiar with the unit’s speed and feed rate.

In this article, we will be discussing details about slitting saw speeds and feeds. From learning the basics of these measurements to discovering how to calculate them, here is everything you should know about these features!

Chapter 1.Slitting Saw Speed Basics

Slitting saw speed illustration
Caption: Slitting saw speed illustration

What is the cutting speed when using a slitting saw? Although you might assume, it is worth defining the basics before you get to work. The speed can refer to in a couple of different units. The first one is “meters,” and it is used primarily in Europe. If you are in the US or some other areas, you might use “surface feet.”

Either way, you will be calculating the desired unit per minute to get the slitting saw speed. In most cases, you will find it described as “surface feet per minute” or SFM. As for the surface fleet, it aims at the speed of the cutting edges as they come in contact with the material.

The general rule for the speed is that it is reversely proportionate to the tool’s size. For example, if you are using a large slitting saw, you will need to operate it slowly. Lowering the speed will ensure higher precision and adequate cut smoothness. You could increase the velocity, but only if you use a generous amount of coolant.

If you use a cutter with a smaller diameter, you will need to use a bigger number of RPM because of the different distances from the middle. Although it depends on other conditions, too, titanium and hard materials use low speed. On the other hand, aluminium and other light materials go with 2,000 SFM or bigger.

Chapter 2.What Is a Slitting Saw Feed?

Caption: A worker cutting concrete with a diamond saw

Now that we got the speed basics out of the way, let’s discuss slitting saw feeds. First, let’s take a look at the definition of the feed rate when it comes to cutting tools.

The feed rate describes the tempo at which the cutting tool gets into the material. Similar to the speed, you will have the choice of two units. The first one is millimetres, and the other in inches. In most cases, you will be using inches per minute, which also described as IPM.

The tool you use and the workpiece material will affect the feed rate. You also need to consider the effective inserts placed in the tool. The positioning of the inserts could affect the feeding rate. You want to know if each insert follows an identical path during the cutting process.

You can use this formula to determine the feed rate in some tools:

IPM = (feed per insert) x (number of effective inserts) x (revolutions per minute)

Chapter 3. Beware of Extreme Heat Ruining the Slitting Saw

Caption: Steel cutting tools used for cutting with sparks

Excessive heat is never good news for the cutting tools, and that is true for slitting saws, too. The important thing to consider is that you always want to avoid overheating since it comes with a myriad of issues. You could damage the workpiece and ruing the cut, but you can also compromise the tool. That means you might not be able to use the unit for other projects, which is bad news.

Now, the general rule is that higher speeds also mean increased heat. If you are cutting the material fast, you are at a bigger risk of overheating. That is why you should be careful when increasing speed.

If necessary, don’t hesitate to use the coolant. Furthermore, you could benefit from using a lot of water or another method to cool down the temperature when working with a slitting saw. If you are a beginner, it is essential not to force things. Take it slowly and try to estimate whether the heat level is optimal. If you notice that the temperature is too hot, either reduce the speed or find an alternative to reduce the heat.

Chapter 4. Slitting Saw Calculating Speeds and Feeds Manually

Using a calculator to calculate slitting saw speeds and feeds
Caption: Using a calculator to calculate slitting saw speeds and feeds

Your first approach is to enter the slitting saw speed and feed calculation manually. Some users might tell you that using two teeth in work is the right way to go, but that isn’t necessarily true. It is a rule that operators commonly use with band saws. However, it is only partially true when it comes to slitting units.

The rotations per minute requirement should be calculated depending on the material of the saw. For example, if you are using a carbide blade, it won’t have the same RPM as high-speed steel. That is why you want to consider the tool material first.
The overall equation used for calculating the speed is the following:

(Speed for doing the cutting) / (Diameter of the tool) x 4

That calculation will result in the rotations per minute (RPM) you should use during the operation. Now, that is only the beginning of the procedure. The next thing to do is to consider the feed rate.

Here is the general calculation to use:

(Number of teeth) x (number of teeth) x (chip load per tooth)

The result will be the feed that you can use while operating the saw. The critical thing to note is that different materials have various rates for efficient forming of the chips. That is why you might want to turn to ratings of machinability. The odds are that the manufacturer or the internet can provide you directions when it comes to the preferred chip load for specific actions.

However, if the materials are not the ones frequently used, having sufficient practice is the only way to secure an optimal calculation.

Chapter 5.Pros and Cons of Using Software When Calculating Speeds and Feeds

Man pressing the buttons on a laptop
Caption: Man pressing the buttons on a laptop

Does calculating slitting saw feeds and speeds manually sounds difficult? Would you like an easier way without going through the trouble of doing the math yourself? If the answer is yes, perhaps you can consider using specialized software when calculating speeds and feeds.

It might sound tempting, but using these programs comes with both advantages and drawbacks. The main benefit is that you don’t have to go through the hassle of doing the calculation yourself. The machine will divide and multiply everything required, which minimizes room for human error when it comes to calculating.

However, that doesn’t mean that mistakes can’t happen. Even the software relies on the user entering the required information. That might imply measurements like saw diameter and other details. They need to be accurate so that the program can calculate the required measurements easily.

Depending on the app you use, they might suggest the preferred speeds and feeds depending on the material you are cutting. That could give you useful pointers on where to start when cutting.

Chapter 6.Double-Check Everything Before Starting

Caption: Double-check illustration

Once you perform the calculations, you will have the measurements required for slitting saw speeds and feeds. If you entered all the information right, the data you received should be reliable. However, if you want to be sure, double-check everything again.

You don’t want to risk cutting with wrong measurements because that can bring a wide range of issues. Apart from taking longer for an optimal cut, you risk damaging the workpiece and the entire tool.

That is why you must secure accurate information before starting. The crucial thing to note is that the measurements you received are merely initial points. No calculations can beat the actual user experience. If you feel that a faster or slower speed should be better, or the feed rate should be different, go for it. However, most users try with the initial settings first and then make the desired adjustments.

The conditions you work in could also impact the targeted slitting saw feeds and speeds. The sharpness of the saw and other details affect the ideal settings. The good news is that calculations will provide somewhat accurate guidelines so that you know where to start. Once you begin, make sure that everything looks and feels right.

1.Carbide-Tipped Drill Bit

The use of carbide (either tungsten or titanium) on cutting tools to improve performance and effectiveness is popular among manufacturers. The superior material properties of carbide make them a suitable addition to a drill bit for cutting stone. The strength and toughness of the carbide-tipped drill bit make it the perfect tool. Another advantage the carbide-tipped blade has over other types is its service life, which is remarkably longer than other stone cutting drill bits.

The carbide-tipped drill bit structural composition comprises two components: steel for the body and the carbide for the blade tip. The strength of the carbide tip can cut almost five times as much as its other counterpart, like the HSS drill bit.

The carbide tipped drill bit is reusable if you happen to have a case of bluntness. All you need to do is to re-sharpen just as you would sharpen your typical drill bit. The same goes for the carbide-tipped drill bit, with the only difference remaining that you might need a coarse grinding stone because of the carbide toughness.

The only downside to using a carbide-tipped drill bit is the cost, as it costs remarkably more than any other stone cutting drill bit. Nevertheless, for longer service life with more effective cut, choosing the carbide-tipped drill bit will prove not only effective but also economically better.

2.Diamond Core Drill Bits

As builders, sculptors, and other professionals find more use cases for stone, they also find a more creative way of cutting stone. A critical method of cutting stone is the diamond drilling method. The way the diamond drilling method works is that manufacturers infuse diamonds with drill bits on the end of the diamond drill bit tip.

These tips have different configurations that make them cut stone differently. There are fundamentally two different tip variations for cutting stone, namely:

•  Solid-tip diamond core drill bits

•  Hollow tip core drill bits.

Solid tip diamond core bit has a unique structural design that contains diamonds on its tip and edges. This structural design gives the core drill bit a different cutting mode, which is mostly boring a hole by crushing stone the side of its cutting tip and edge.

On the other hand, they cut stone by making a hollow path in the stone for hollow-core drill bits. The reason for this is because of the configuration of the hollow bit cutting tip. They have diamonds along the edge of the tip and marginally up the sides of the hollow tip. The diamond hollow core bits cut stone at the edge of the tip as opposed to the full breadth of the tip.

These different variations, however, have various applications. Hollow diamond core bits are secondary cutting tools as they open spots that have the solid tip bit cuts. Solid tip, on the other hand, will cut out a complete hole in the stone. And sometimes they can also cut larger stones.

3.Masonry Drill bit

Masonry Drills Bits belong to the twist drill family, with just the structural composition of the masonry drill bit the difference in the masonry drill bit. The masonry drill bit comprises a softer steel variation and a carbide tip that manufacturers braze into the steel as the cutting edge.

Most users use the masonry drill bit along with the electric hammer drill, which serves as the power source for the cutting tool for cutting into tone. The electric hammer is what breaks down the stone. After breaking the stone, the flute of the drill bit then cuts through the stone until it gets to a new point where you may need to break again.

Standard masonry drill bits are available in a diameter range of 5mm-40 mm. You can find special masonry drill bits that come in at about 1000 mm, solely for use with smaller handheld power tools. They are most popular among users operating in domestic residences for wiring or plumbing.

If you plan on doing a great deal of work around the home, at that point, you might need to buy a complete set of a masonry drill bit. The complete sets give you the greater hole size flexibility and the attachments you can use for drilling.

In the end, your choice of masonry bit depends solely on the amount of material you are looking to cut. Operators carrying out domestic applications often tend only to buy a few instead of the complete set. Only industrial or large-scale operators move to buy an entire set of a masonry drill bit.

4.Concrete Drill Bit

For any individual that cuts stone or materials with similar hardness, concrete drill bits are one of the most important tools. A good concrete drill bit will make your experience in stone cutting considerably easier. So, the concrete drill bit is a must-have for any operator looking to cut stone.

Concrete drill bits have a very similar design with HSS, wood, and even metal drill bits. They have a steel shaft and spiral edges (flutes) which carry out the cutting operation. Hitherto, the concrete drill tip also has a slope, which is essential because it allows easy flow of concrete bit from the cutting point.

Some variations of concrete drill bits also contain embedded diamonds to help them cut faster and more durable. Since diamonds are generally hard, they can drill into concrete without necessarily becoming blunt. Likewise, this implies an increase in cutting precision because of the diamonds as opposed to a worn-out, chipped surface.

Other variations like the hammer drill is also an option you can combine with your concrete drill bits to make smoother hole cuts. The hammering activity will help cause the bit to drive further into the stone or concrete. After this, the flute of the concrete drill bit continues the cutting process. The hammer drill is an accessory that can prove useful.

There are also speciality concrete drill bits. An example of such is the rebar bit, which is
suitable for cutting the outer segment of stone or concrete. There is also a speciality concrete
drill bit for making smooth cuts.

The operator’s choice of a concrete drill bit is very crucial. In a cutting industry with a lot of inferior tools, the operator will need an effective tool to perform well. They will also consider the necessary accessories that will make for more effective cutting of the stone. Another important factor the operator considers is the economic effectiveness of their choices. Though there is a lower cost concrete drill that can cut the concrete, it is better to have a smooth hole when cutting stone or concrete.

Stone cutting is a popular practice among professional, skilled users and unskilled operators. Cutting stone can be a little complex and difficult if you don’t have the right drill bit.

Manufacturers have provided different types of stone-cutting drill bits to cater to the demands of different users and applications. This article outlays four major types of stone-cutting drill bits.

In conclusion, therefore, as you continue to look out for helpful tips to help cut stone better, look no further, NCCuttingtools has got you covered.

Slitting Saw–6 Tips for Selecting the Correct Slitting Saw

Slitting Saw

Slitting saw have been in use for a long time and are popular among users looking to make narrow or deep cuts in metal. However, a common problem is knowing which slitting saw will make the perfect fit for the respective applications.

Manufacturers have catalogues of different slitting saws with various peculiarities for different jobs. This article will look to help you with tips to find the best slitting saws for your application.

Slitting Saw
Figure 1: Slitting Saw

1.Saw Arbor

Slitting saws design requires that there is support for the blade to connect it with the slitting saws assembly. The saw arbour is the shaft that extends from the slitting saw assembly to the blade. It is this shaft that the slitting saw motor drives to rotate the saw blade safely.

It should be evident now that the shaft diameter is an essential factor you must consider when choosing a slitting saw arbour. The hole that the shaft connects to within the blade is the arbour hole. For smooth and effective cutting, both the arbour hole and the arbour must be a perfect fit.

The arbour hole is directly proportional to the slitting saws blade outside diameter. As the outer diameter increases, the same goes for the arbour hole. As a general standard by most manufacturers, blade diameters in the range of 8″-10″ have an arbour hole of 5/8″. Ultimately you must ensure to check the manufacturer’s catalogue to know which arbour hole suits which blade diameter.

Now, if your job description demands that you cut a material that you hold with a vice, you might need a different type of slitting saw assembly. In such peculiar cases, you will a customized saw assembly that has an arbour with a deep cap.

2.Number of Teeth

Having the correct number of tooth count is essential for an effective cut for any project. Depending on some special applications like those demanding a fine cut, you will need a slitting saws blade with a higher tooth count. When it comes to tooth count for slitting saws, there are two major types namely;

1.Standard Tooth Slitting Saw blades

2.Coarse Tooth Slitting Saw blades

Standard Tooth Slitting Saws Blades: are slender with a higher number of teeth than its counterpart, the coarse blade. You will need this tooth count when your job description demands a smoother finish. Since more teeth are available, the feed rate can be higher than that of the coarse tooth saw blades. The only downside to using the Standard tooth saw blade is the cost price, which is considerably higher than the coarse saw blade. It is understandable because of its tooth count.

Coarse Tooth Slitting Saw blades: They are scanty slitting saws with less tooth count than the standard tooth blade. Famous for their simple and basic cutting, they are mostly applicable for large scale cutting with no attention to finish. The coarse tooth slitting saw blades have more prominent flutes compared to the standard tooth rendition. These flutes enable the blade to remove more chip. The coarse tooth saws are usually cheaper than the standard tooth saw blades mainly because of the lesser tooth count.

In the end, the slitting saw blade with more tooth count would cut cleaner than that with a lesser tooth count.

3.Type of Blade Material

Slitting saw blades often come in different material composition types, and there is a good reason for these varieties. Frequently, users have to cut various metals with different properties, strengths, and compositions. Due to this, users consider many factors before choosing the best slitting saw blade for their application. They consider things like cost, blade life, blade strength, etc. Hitherto, manufacturers have succeeded in having just two variations for the slitting saw blade material, namely;

1.Carbide-Tipped Saw Blade

Making blade tips with tungsten carbide is not a new practice for manufacturers. They are popular in use for most cutting tools. Tungsten carbide comprises of metal joined with carbon with a Mohs Scale rating of about 8 and 9. With a carbide-tipped saw blade, manufacturers often tend to make the body structure compose of steel. They mostly braze carbide tips on to the steel body to make the carbide-tipped slitting saw blade. A decent carbide tip can last up to ten times longer than the HSS slitting saw blade

Most slitting saw blades aren’t made entirely of carbide purely because it is a more economical perspective. For this reason, manufacturers stick with using steel as the body because of its superior strength and durability.

Carbide-tipped Sawblade

Figure: Carbide-tipped Sawblade

2.HSS cutting blades

High-Speed Steel (HSS) means treated steel. During the treatment process, the steel improves its strength, toughness, and durability. Quality HSS slitting saw blade can cut metal cylinders, auxiliary and strong metallic sections.

The HSS slitting saws blade consists of tungsten and molybdenum. After heat treatment of the steel, the tungsten and molybdenum help to improve hardness and sufficient durability. A specific level of tungsten in the blade is necessary for the right amount to create wear-resistant carbides. The tungsten also helps improve the mechanical endurance of the HSS slitting saws blade.

HSS saw blade
Figure: HSS saw blade

4.Slitting Saw Blade Thickness

Slitting saws blade thickness is critical as it determines the type of material you can cut. The manufacturing standard of most blade plate thickness is within the range of 1/8 -1/4 inch. Thinner blades, however, have their advantages with lesser waste bye-products. They are prone to wobbling and sometimes overheating. On the other hand, the thicker blade has a firmer grip on the material, providing you with more stability when cutting.

5.Slitting Saw Blade Size (Diameter)

The blade diameter is simply the length of the line between the tips of two of the blade’s opposite teeth, which follows through the blade’s centre. The blade diameter is also the size of the blade. All other segments of the blade are in alignment for the blade’s width. Ordinarily, you can only use specific blade diameters for particular applications. Attempting to use a bigger blade diameter for a smaller application will tie up the saw.

Until recently, the most well-known blade diameters from different manufacturers are in the range of 6-1/2″, 7-1/4″, 10″, and 12″. It is also important to note that you can only use slitting saw blades with a smaller diameter for saw operations. In contrast, bigger diameter blades are famous for their fixed saw application. Blades with smaller diameters are useful for faster cuts, simpler, and thinner metals. Manufacturers have also stated that the cutting ratio of the blade diameter is 0.3.

6.Kerf Width

The width of the slitting saws blade kerf is the widest of the blade tooth. The kerf or blade thickness is an essential part of the slitting saws blade as it is the segment that cuts in the material. It is vital to have wider kerfs for more effective cutting for cutting metals with slitting saw blades. A blade with thinner kerf might have complications like wobbling and sometimes complete breakage. However, the blade kerf width does not stand alone as it is directly related to the blade thickness.

Blade Kerf
Figure: Blade Kerf


A slitting saw is a cutting tool that is popular among professional, skilled users and unskilled users. The slitting saw is a perfect fit for the different materials you can imagine to cut.

Manufactures have provided different varieties to cater to the demands of different material properties. This article outlays the various tips you will find very useful when choosing to buy a slitting saw.

2.Cutting of fused glass

Before going further, let’s briefly analyze how pertinent a glass ring saw is to cutting fused glass. We must examine the technology behind fused glass itself. In case you are wondering what a fused glass is, it is a type of glass made form melting different pieces of glasses together at high temperatures up to 820 degrees Celsius. Once these glasses have been melted together and formed rightly, how to cut and avoid breakage comes into play.

Already, when setting-out to produce this fused glass, manufacturers should have considered the compatibility of the constituent glasses. Often, manufacturers already perform their tests to determine the compatibility of the glasses they intend fusing before commencing. The importance of this test helps to determine the strength and integrity of the final product.
Having picked your preferred fused glass for your project, then you need to cut it to shape. If you are a glass art enthusiast, then the glass ring saw is a must-have for you. Rightly investing in an equipment such a glass ring saw is a great plus for you as a glass artist.

3.Cutting very thick glass

What comes to mind when you hear very thick glass? Thick glasses are known for their application in both residential and industrial/commercial purposes. In some cases, you can call them heavy-duty glasses. With the glass ring saw blade, cutting this type of glass has never been easier. Below are the range of glass thickness mass-produced with their specific purpose-

3/32″ (2mm)- known for picture framing.

1/8″ (3mm)- For end tables, windows, picture frames, and insulated units.

3/16″ (5mm)- For shelves, small tabletops and insulated units, etc.

1/4″ (6mm)- For protective covering on tables, insulated units, paned windows, shelves, and shower doors.

5/16″ (8mm)- usage is similar to 1/4 inch, but not common in the US market.

3/8″ (10mm)- For office portioning, walls, shower doors, handrails, used in shower doors, tabletops, glass walls, glass partitions, bars, door lights, etc.

Of all the thicknesses listed above, the very thick ones range from 3/8” up to 1”. Over time, thick-tempered glasses have found their way into the heart of architects and designers. Often, the 3/8″, 1/2″ and 1″ are commonly used for retail stores, modular offices, tabletops, reception desk, etc. The reason for adopting thick glasses for this purpose is not far-fetched as cracking must not occur at all.

In this case, cutting thick glasses with glass ring saw is essential if you are into this business or industry. The diamond coat around the blade enables it to penetrate deeply into the depths of thick glasses conveniently. Consider purchasing this glass ring saw to help you pull off smooth cut on these extremely thick glasses.

4.Cutting drapery glass

Unlike other glasses considered in the previous section, this type of glass is different and unique. Whenever you come across a cloth-like, well-folded, and wavy glass usually associated with uneven thickness, then it’s a Drapery glass. Drapery glass has its front and rear side not equally thick, meaning it’s not flat. It could significantly affect the cutting and overall ease of handling this glass.

A glass ring saw befits this purpose due to its ability to cut in any direction in a bid to cut properly. Often, this glass is fused and stained in nature; i.e., it is a product of different melted glasses with different colours, which makes it stained. For this reason, before advancing to cut this glass, you must score the pattern with the saw. Scoring involves making an initial outline of the pattern you want to cut. Scoring the glass helps to avoid any possible case of breakage or chip falling off the edges.

As you set out to cut, you need to observe the following features of the drapery glass. Firstly, on the front of some drapery glass, the folds appear to be reversed while the rear is hollow. In other cases, the rear side is flat, and the folds are on the front with visible thickness in places.

Secondly, after carefully classifying the nature of the drapery glass, you must cut from the surface with the least irregularity. Watch out for the reverse side of the drapery glass for marking out your pattern over the drapes’ front side. More irregularities imply thicker glass, which makes it more challenging to cut than a flat side or lesser irregularities.

Thirdly, position your glass in such a way that you can easily cut the proposed pattern. Lastly, ensure you score the outlined pattern before fully cutting with the glass ring saw.

Note that with the glass cutting ring saw, you need not polish your workpiece as the cut is always perfectly executed.

5.Cutting small pieces

Here, the glass ring saw has a lot of advantages due to its design. The tabletop attached to the saw makes it easy to cut extremely small glasses accurately. Again, tiny bits of glasses have proven to be a valuable asset to a glass artist. Mosaic artists find these small bits of glasses useful as well. You can either cut out small pieces from off-cuts or large sheets of glass. You can decide to decorate with small glasses. You can also opt to join different tiny bits into a piece of artwork. In essence, a glass ring saw can cut your glass into sizes; even a handheld cutter cannot achieve. Over the years, many glass artists and enthusiasts have attested to the relevance of the glass ring saw.

5 Tips for Choosing the Right Diamond Tile Drill Bits

Diamond Tile Drill Bits

Drilling holes in tiles are somewhat unavoidable. The diamond tile drill bits may be the tool of choice, but the right choice of these tools is paramount to achieving the desired result.

Although there are other different types of drill bits, examples are carbide drill bits, steel drill bits, and many others. But diamond bits are the most selected.

Here are some tips on the factors you should consider when making your choice of diamond tile drill bits.


5 Tips For Making a Selection

Using the right diamond tile drill bit confers more advantages to you than you can think of. The tool allows for consistent performance in all jobs and even causes lesser damage to the drilled materials. More importantly, it is more durable than most types of drill bits available.

1.The Material You Want To Cut:

Tiles made of different materials, and also there are varieties of materials that you can drill using a diamond tile drill bit. However, it is very important to consider the type of material that you would be drilling with the diamond tile drill bits you are choosing. Different materials have different hardness and abrasiveness properties.

For example, the common types of tiles are majorly ceramic or porcelain. Porcelain tiles are harder than normal ceramic and require much more sophisticated tools to drill. When drilling, the use of diamond drill bits for porcelain tiles is the only viable option because other drill bits cannot possibly cut past the tile due to its extreme core hardness.

The cost of the material used may also influence the choice of the tile drill bit tool. Expensive materials require a perfect finish with minimal damage. Choosing the diamond tile drill bits tools that will ensure these requirements met is the first step to succeed on the job.

Figure 2: Image of a constructor with ceramic tiles

2.Diamond Concentration:

Another thing to look out for is the concentration of diamond present in the diamond tile drill bits. It is the percentage and distribution of diamond in the tool. It has an overall effect on drilling efficiency.

The selection of the right diamond tile drill bit for the material you want to drill is important. This because it is critical in the optimization of your drilling operations. It is critical because it plays a major role in the determination of the drilling speed and lifespan of diamond tile drill bits.

When you want to drill very abrasive materials, manufacturers would recommend you use a diamond tile drill bits with high diamond concentration. If your material is less abrasive, choose a low diamond concentration bits. It is easy to know because of the work of the tile drill bits manufacturers.

They ensure the optimal performance of these tools by using their analytical capabilities and technical experience to balance the diamond concentration in diamond tile drill bits. It helps them to achieve optimum performance. So you must consider this factor before choosing.

Figure 3: Image showing an image of diamond particles

3.Size of Holes You Want To Drill:

The size of the holes you want to drill is also an important factor to consider when choosing the tile drill bits. There are different applications of the diamond drill bit tool, and each application has specific details that determine the number and the size of holes you would be drilling. The size of the hole you would be drilling will determine the method of drilling that you should use and thus, the type of diamond tile drill bit to use.

Ascertaining the diameter of the holes you want to drill in tiles is a wise thing to do because it will inadvertently result in the choice of the right tool for the job. As a beginner, if you are unsure about how to measure these holes, there is a way out. You could consider using a small wood as a template.

Drill a hole into the wood with any tool that is available to you. Make sure the hole is the same diameter as you would want on the tiles. You can take the measurement with tape and take the diameter along and cross-check with tile drill bits manufacturers’ recommendation.

4.Bond Type:

As with every diamond tool, there are different ways the diamond bits bonded in the tool. There are more than two different ways manufacturers could embed the bond matrix of the diamond tile drill bit. It could be Bonded or Sintered.

The tip of diamond tile drill bit has its diamond bond to the edge of the tip. Manufacturers do this usually through an electroplating-like bonding process. This bond type of diamond tile drill bits is relatively slow and less expensive than the other type.

When you are drilling the tile, the bonded diamonds on the tile drill bits mostly wear off the tool. It happens because of the hardness and abrasive resistance of the tile or porcelain you are drilling. Tile drill bits with this bond type usually consists of just a single layer.

So after wearing out, the best thing you should do is to replace them with new drill bits. Manufacturers do not recommend tile drill bits of this bond type for any other material except ceramic tiles. It usually does not work well for porcelain.

The tile drill bits require proper speed and adequate lubrication with water. The other bond type is the sintered diamond tile drill bit. These tile drill bits have their diamonds directly inside the steel tip.

Therefore, when you are drilling your tile, as the metal tip wears off, new diamonds resurface. It happens because the sintered diamond tile drill bits have more than a single layer of diamonds on the tip. Unlike the other bond type, you can drill porcelain efficiently with tile drill bits of this bond type.

Even though there are multiple-use diamond tile drill bits, different bond types are best suited to different kinds of jobs and also, subjective to the discretion of the user.

5.Lifespan and Cost:

Tile drill bits lifespan depends on several factors. They range from hardness, thickness to the abrasive quality of the tiles and porcelain you are drilling. You can also affect the lifespan of the bits with the level of speed and pressure you use during drilling.

However, with good use, diamond tile drill bits have a long lifespan. For example, bonded diamond tile drill bits last long when you use them to drill tile or porcelain at a relatively low speed.

However, should you decide to use it to drill holes in porcelain, do so at a much slower speed? This simple guideline indirectly determines the lifespan of the diamond tile drill bits. It shows that the diamond tile drill bit would overheat due to excess drill speed and pressure.

The lifespan of diamond drill bit varies according to the type of material you are cutting, lubrication drilling speed, and pressure. It could also be on the bond type. Sintered bond type lasts longer than the bonded type.

Conclusively, the last thing to know is the cost of diamond tile drill bits. In comparison with other types of tile drill bits, diamond tile drill bits might sound expensive. However, if you want the best quality bits to drill your tile and porcelain, you cannot compromise.

If you are not on a tight budget, you should get the diamond tile drill bit. Since they are of two bond types, they cost differently. Bonded type of diamond tile drill bits is less expensive than the sintered variant.

After choosing the diamond drill bits, it is also important you know how to use it efficiently to get the results you desire. Only when you know how to utilize diamond tile drill bits fully, will you find them beneficial. One thing to note is that no matter how much you know how to choose the right diamond tile drill bit, getting the best performance is dependent on the right exploration of the diamond tile drill bit.

Huge costs of operation, imperfect jobs, and profit loss are implications of the wrong choice of the diamond drill bit for tile drilling.


It is, therefore, imperative that every necessary factor is put into consideration before the choice made. A right tool is what guarantees a perfect job.

Following all these tips would help you choose the right diamond tile drill bits.

9 Things You Need To Know About Core Bore Bits

Ongoing Wet Drilling

Diamond core bore bits have saved many artisans and house owners the stress of drilling traditionally. Unfortunately, a lot of people do confuse the traditional method of drilling with the Diamond drilling method. It has encouraged movement while digging and also drilling up to 21/2 inches in diameter, and up to 6 inches deep can be possible in just six minutes.

In this article, we will reveal some interesting facts and features of Diamond core bore drill bits that could make your next drilling efficient and lessen the time taken to complete your drilling process.

Features of Core bore bits

Let’s briefly examine the features of core bore bits before we progress into checking the facts.

1.Maximum Cutting Speed and Wear in Heavy Drilling.

Unlike traditional methods of drilling that are time-consuming setting and overwhelming, most drilling bit companies have technologically-improved their diamond products core drill. If you lay your hand on a higher concentration of a Diamond core that has a segment of up to 11/4-7 UNC, you will worry less about the speed because it takes just 6 minutes to drill through a diameter of 21/2 inches.

2.Highly Durable

The life span of diamond core bore drill bits is always long due to their hardness and toughness. Once you maintain a drill adequately, it suffers fewer defects, such as breakage. However, it can be prone to wear and tear due to frequent usage.

3.Ability to drill a large concrete in a wet area

Drilling in wet conditions is one of the best uses of diamond core bore bits. The drill always has a speed regulator that decides how fast the bits drill. When drilling in wet conditions, the drill core bore bits are less prone to overheating, which can cause damage and would not wear off quickly. It is the direct opposite of dry core drilling. Also, there are specific drill core bits that drill only on wet conditions for optimum results.

9 Facts about the Diamond Core Bore Bits

These are the nine facts you should know about the diamond core bore bits:

1.Trouble-free drilling in heavily concrete

Concrete with heavy reinforcement has always proven to be a hard task for most artisans/engineers or drilling using the traditional approach. However, that should not be a problem when it comes to working with a diamond core. All you need do is to get core bore bits that don’t shed quickly on hard concrete rocks. Once you lay your hand on a good one, you will not only get an optimum result but also enjoy the drilling process.

Drilling core bits are easy to set up and even self-explanatory. For instance, when you purchase your tools from NC Cutting Tools, you can visit their blog for instructional tips on how to use your diamond drilling tools.

4.Low Maintenance Cost

Do you even know that Diamond core bore bits are all manufactured to be self -sharpening? Most core bits remain sharp throughout the drilling processes. However, if your drilling parameters do not correctly align with the material you’re looking to drill, the diamonds on the face of the bit may become worn out without the matrix abrading away. The good news is that re-sharpening is an easy DIY process.

5.Uneven Percentage of Diamonds

Diamond core bore bits are robust and very hard because of the percentage of diamonds that is present through its segment during the production method. This diamond laying across the segment approach has gone a long way to ensure that every bit produced doesn’t wear out quickly. Diamond bits manufacturing process involves welding through the use of both the hot-press sintering method and the brazing method. This process has made it possible to arrange multilayer waterways that crease the matrix height, which could improve the life and efficiency of diamond coring bit.

6.Drilling at a slight angle to obtain optimum performance

If you are drilling holes in ceramic or porcelain stoneware, you would not need the conventional wisdom of drilling to operate using the diamond core bore bits. Slightly tilt the drill and slowly bring it back in a vertical position once the drill is penetrating. It will allow it to last long, plus it will optimize the working speed. This method can be most efficient when drilling sturdy stoneware.

7.Metal bonded diamond core bore bits are good for hard materials.

If you’re looking to drill hard materials, we advise that you go for metal bonded diamond core bore bit. Why? Metal diamond core bore bit come with sintered diamonds. Metal-bonded diamond core bore bits are a combination of different sintered/hot-pressed metal alloys. This sole reason for this combo is to achieve the best cutting performance on hard materials such as glass, optics, granite, ceramics, tile and the likes. The metal bond holding the diamond must wear away evenly and continuously to keep exposing the diamonds to cut the materials in question.

8.Hybrid bonded diamond core bore bits are best for critical finishes.

Hybrid bonded diamond core bore bits are best for critical finishes. In addition to that, they have a high level of drilling speed, consistency, durability, and aggressiveness. In a drilling project that requires a minimum amount of polishing, chipping, lapping, and the likes, a Hybrid-bonded diamond core bore bit is your best bet.

9.Electroplated diamond core bore bits generate less heat during drilling operations.

If you’re looking for tools with freer and faster drilling speed with minimal heat generation, then electroplated diamond core bore bits would serve you well. However, they perform better with softer materials than harder materials. Using them for harder materials would cut down on their durability level.
