1.How to use Slitting Saw cut Deeply

A very questionable decision most users of the slitting saw blade face is how deep they want their cut to go. This dilemma originates from the fact that the number of passes users want their saw to have to cut the material successfully. Some users prefer to have their saw cut through the material once, and they have believed so with good reason. This category of users find that their slitting saw operates more effectively and safer, because there won’t be any build-up chips in the cutting slot.

Most users, on the other hand, believe in using their saws to pass through their material more than once, maybe twice or more. Such groups claim that their material will have a neater and more precise finish that way. That said, there is no rigid approach to how many times you can use your saw to cut through your material. It is possible to push your saw to cut in far more passes or lesser passes and still get a suitable outcome.

In truth, your choice will depend on how much you know about your project, and if you have the adequate setup to execute your project.

2.Choose the right Slitting Saw blade type

The blade of the slitting saw is another essential part of the saw. In this case, the slitting saw blade can come in different types depending on the cost or preference. These blades have unique features that make them special in their rights. However, in a bid to achieve maximum efficiency the top two blades that you can use for your slitting saw blade is;

• Carbide-Tipped Blade

• High-Speed Steel (HSS)

The carbide-tipped blade is famous not only for its rigidity but also for its cutting efficiency. The carbide tipped blade in the slitting saw is the perfect definition of precision and accuracy. Besides, the carbide on the blade tip enables the slitting saw to cut harder materials with more efficiency. The only flip side to this blade is the high cost. The carbide is a tough material and also rare, which makes it sell at a very high price point.

The High-Speed Steel, on the other hand, is a perfect substitute for the carbide tip saw blade. Yes, the steel may not be as rigid as the carbide, but it can cut reasonably well. The high-speed steel is cheaper than carbide and also durable.

It leaves you with two options. You will have to choose between a more expensive carbide-tipped blade or the high-speed steel that makes as a cheaper substitute.

3.Select the right slitting saw arbor

One of the crucial parts of the slitting saw is the arbor. Proper considerations must be made before selecting an arbor. A quick suggestion when getting an arbor is always to get one that has a deep cap and a low profile. The deep cap, coupled with a low profile, is necessary to create the required margin or clearance between the blade and the material you choose to cut.

This clearance is solely dependent on your discretion because of the different types of cuts available. Some users prefer to have a single cut through, which will require lesser clearance while others opt for the reverse.

This low-profile arbor is essential because of the different special applications of the slitting saws that make it cut faster and better. Reasonable consideration of the arbor will always leave you having a superior cut compared to other saws for the same application.

4.Always Use a Thick Blade slitting saw.

For slitting saws, the geometry of the blade matters a lot. It is because it dictates the type of material you can cut. One of the best tips for using slitting saw is to always go with thicker blades. The thicker the blade, the easier it is for you. Thinner blades tend to be unstable, which can sometimes lead to shattering of the blade.

If you are a beginner, you must use the 1/16 inch saw blade. The 1/8 inch saw blade is also a must-have for beginners. It allows you to be able to control easily control the blade to obtain a more precise finish and, ultimately, quality cut. Besides, this type of blade eliminates the risk of shattering because they have more strength.

5.Check your Feeds and Speeds

As a user of slitting saws, one of the first things you will notice is how quickly the blade gets hot. The slitting saw is not like the regular saw because they are quite small and weigh less. Hence, any mistake made by operators when running the slitting saw can be costly. Operators may run their slitting saw at normal feed or speed rate and still ruin the tool. Therefore, you must calculate the speed and feed for every application. This calculation will not only protect you but will keep the blade operating at top efficiency.

As a rule of thumb, larger slitting saws should run slower. Also, you must supply enough coolants along the cut paths. It allows you to cut fast and prevent the breakdown of the saw.

6.Use Coolants

Friction is not a new phenomenon for cutting with saws, and the slitting saws is not any different. Your slitting saw is very susceptible to overheating, and sometimes this can grow to become a huge problem. It can cause production halts and downtime, which invariably leads to loss of money.

You can avoid such cases if you apply cutting fluid (coolant) to the surface of the material. Coolants are best used in instances when you aim to carry out long cut paths. The coolants will let you cut faster, thereby providing more efficiency and, at the same time, protect you from saw damage due to friction.


A slitting saws is a cutting tool that is popular among professional, skilled users and unskilled users also. Famous for its multiplex of applications in of precise finish and smooth cutting, the slitting saw is a rare gem. This article points out the different tips you can carry out to help maintain high efficiency and, at the same time, remain safe.

Specialty Blade–5 Tips for Choosing your Specialty Blade

Various styles of saw blades

Cutting blades has evolved from your traditional standard modules to specialty blades for specific cutting. With the different types of materials present today, most users face a challenge of how to get a perfect cut on them. Nevertheless, there are various things to consider before choosing your specialty blades, from the type of material in the kind of cut. Hence this article is to help guide you on the different factors to consider when choosing your specialty blade.

1.Specialty Blade Length, Width, and Thickness (Blade Geometry)

Today we have different types of materials that are sometimes very tough or very thick. Cutting materials of this calibre requires the use of specialty saw blades. The geometric design of the module you choose will also vary depending on the nature of the material. It invariably means that for thicker materials, you will need a more compressed and broader specially-made blade.

For a specialty circular saw blade, the diameter tells a lot about what the module can do. This diameter is the total distance between two opposite ends of an edge. Now even though circular saw blades are famous for cutting wood, they can also cut other materials. However, for them to be able to cut different materials, they must be customized to match the material properties. A good example is cutting materials like plastic with specialty circular saw blade; you must ensure that the plastic is 15% of the blade diameter.

In summary, in considering choosing a specialty blade, the blade geometry is essential. To get the best type of cut for the different materials present will need that you specific geometrical changes to your edge.

2.Specialty Blade Type of cut

The kerf of a blade is a slot that is responsible for cutting a material, which makes it an essential feature to consider. This kerf width is responsible for how much material removed when reducing.

Asides the blade geometry, a wider blade kerf will help you cut through material faster. It can be beneficial in many ways; firstly is from an economic perspective. Some users prefer to have their blades cut more material, thereby requesting to have blades wit wider kerfs. Although this type of modules may cost more during purchase, they will save you more money in the long run.

Another way the kerf influences the type of cut is in the number of passes your blade will have over the material. Blades with wider kerfs will cut through stuff with fewer passes than blades with thinner kerfs. In turn, it will leave you with a neater cut. It is, however, essential to note that when choosing a specialty saw blade with wider kerf, you must consider its geometry as wider kerfs will demand thicker blades to be able to support the kerf.

3.The material composition of Specialty Blade

Due to the different types of materials present today, individual blades with the unique material composition are the best way to cut through such materials. A perfect example of such a module is the diamond multi-tool specialty blade. This blade comprises of both steel and synthetic diamonds. These two components already make for a more durable edge. These diamond multi-tool specialty blades ore of different types namely;

• Segmented blades

• Continuous rim blades

• Turbo rim blades

The segmented diamond blades are unique because they deliver a higher amount of power compared to the traditional blade. This blade is designed with diamond edges and can cut more aggressively. They can precisely cut through sturdy materials like concrete. They are popular among users that cut sturdy materials faster.

The continuous rim blades, on the other hand, are specifically made to cut materials like tile. The structural design of this blade is quite different in that it has no teeth, which makes them unable to cut materials like wood.

Finally, turbo-rim blades can cut through sturdy materials like brick. However, they share a very similar structural design with continuous rim blades because they also have no teeth. The turbo rim blades are different from the fixed rim blade because they deliver better cutting power. This power is what makes them able to cut through tough and harder materials.

4.The precision by Specialty Blade

Another significant factor to consider when choosing your specialty blade is the blade’s precision. The way to determine a blade’s accuracy is by its hook angle. This hook angle is the forward or backward lean on every tooth of the blade. In simpler terms, the hook angle is the angle at which every cutting tooth of the blade enters your material.

The angle of entry of a blade is critical as this will determine its feed rate and the way the blade will cut the material. The hook angle of your regular circular saw blade comes in with an aspect of about 5 to 15 degrees positive. Now specialty blades tend to have steeper angles that can go as high as 22 degrees for cutting softer materials like plastic.  While going as low as 6 degrees to cut hard materials like concrete.

These specially customized angles significantly determine the precision of the blade. Most users only seek to have this type of blade whenever they have projects that require high precision. So if you are looking to cut a delicate material with high precision, you should look to have your hook angle customized.

5.Type of material to be cut by Specialty Blade

When it comes to the kind of stuff you want to cut, you have to think about effectiveness. The reason you must consider this way is that the best slab to use may not necessarily be the most expensive. The perfect blade will be that which cuts through the material quickly and effectively.

So before you determine the type of specialty saw blade to use, you must know the kind of material you are looking to cut. Today we have different elements that users seem to cut, materials like concrete, bricks, wood, etc. All of these material need blades with the required;



3.Wear resistance

Hardness is the ability of the blade to cut the material with the required hardness and strength even at points of aerial prowess.

Toughness is the ability of the blade to cut the material without chipping or fractures. It describes how a module can handle shock, bending, and torque forces.

Wear resistance is the service life of the blade in operation without having to be replaced by another module.

7 Tips for Selecting the Correct Carbide Slitting Saw

Picture showing carbide slitting saw

When setting out to choose a carbide slitting saw, you should never settle for less. You need to pay attention to the appropriateness, and overall safety of the saw for jobs over merely getting the job done. With the right saw, you can get the job done efficiently with little or no stress at zero risks.

This article to equip you with the requisite knowledge and understanding in this niche. Furthermore, specific technical details and information pertinent to your selection process are succinctly discussed in paragraphs to follow.

Picture showing carbide slitting saw
Fig 1: Picture showing carbide slitting saw.

1.Types of carbide slitting saw

Bearing in mind that carbide slitting saws are prominent for their high precision and accuracy. Its performance still very much depends on the blade’s tooth geometry and stick-out diameter:

• Tooth Geometry

Below are the tooth geometry variations of carbide slitting saw:

a.Standard Tooth Slitting Saw: This usually comes with more teeth per inch and lesser thicker than its coarse counterpart. Owing to these properties, it can give you a very fine and better finish of your workpiece. Due to more teeth around the circumference, it has a higher feed rate of which also contributes to the excellent finish it gives. It is generally considered ideal for finish passes. However, it is more expensive due to the higher number of teeth.

b.Coarse Tooth Slitting Saw: This has exactly opposite properties to the Standard tooth slitting saw provided all other things are equal. It has a higher thickness than standard tooth lesser tooth per inch, fewer teeth, more opening for better chip evacuation, allows for deeper cuts. They are the best fit where a smooth finish is not critical. The sum of all these properties makes it far cheaper than the standard tooth slitting saw.

• Blade diameter

On the other hand, the blade diameter typically ranges from 3 to 4 inches. You, therefore, have to pick the smallest diameter needed to give you the depth of cut you desire based on the thickness of your workpiece. Also, ensure that at least two teeth of the slitting saw come in contact with the workpiece through the tool’s revolution Note that the larger the diameter, the higher the chances of wobbling and runout.

2.Material to be cut

The nature and type of material you intend cutting informs your slitting saw selection process, it helps you decide how much lubrication you need to avoid chips from getting welded to the workpiece during cutting.

Knowing how tough, brittle, or hard your metal is, help you determine the right saw thickness for you. In your best interest, select the best saw thickness for your application such that it would not break or fail in service at all.

Cutting of Zinc, magnesium, aluminum, brass, bronze, plastics, and none-metals requires a specific type of carbide slitting saw while machined steel, cast iron are also cut with another configuration of carbide slitting saw. Ensure you pay attention to this to get a great saw capable of cutting to your desired depth.

3.Choose an appropriate arbor and saw hole diameter

The arbor carries the saw and is usually attached to the tool holder or spindle taper of your CNC machine. In a bid to minimize deflection and maximize rigidity of the carbide slitting saw, the largest possible diameter of the arbor should be selected. The arbor plays a significant role in the accuracy of your cut. If you choose the wrong arbor, then you are bound to experience great danger as well as risk your workpiece getting ruined. For example, a 1 -inch arbor has half the strength of 1.25-inch arbor.

You should take the length of your arbor into due consideration as well to ensure proper reach.

In the same vein, the saw hole must also complement the arbor diameter. However, as mating parts similar to a hole and shaft assembly, some level of tolerance is needed. The final assemblage of the saw on the arbor ensures the overall rigidity of the assembly and prevents deflection. Do not forget that the larger the arbor size, the larger the saw hole.

4.Extent of cut

No matter how deep you want to cut on your workpiece, the carbide slitting saw can help you achieve this. It just requires some technique(s), which are pivotal to your selection process. Unlike its counterpart- HSS slitting saw, the carbide slitting saw is a specially developed saw with the ability to cut seamlessly through metal mainly.

If you are looking to make deep cuts, there are two generally accepted approaches- The first approach is to make shallow cuts multiple times and progress in that manner. The other approach is to cut to your required depth in a single pass without making shallow cuts.

For the first approach, chips are quickly eliminated and are discontinuous. On the other hand, for the cutting in one pass approach, chips accumulation is likely to cause problems. From experience, the first approach is the most preferred by professionals. It is because it gives the best accuracy and reduces overheating by providing room for intermittent cooling.

5.Be Sure of Your Feeds and Speeds

By a rule of thumb, the larger your carbide slitting saw, the slower it should run. It is to reduce the amount of heat to be generated and minimize deflection and instability. It is, therefore, imperative that you calculate the appropriate feeds and speeds for your use. Even though there are quite a lot of calculators out there to this for you, the fundamental parameters needed are:

i.Your saw’s diameter and the number of teeth.

ii.Your saw’s thickness.

iii.Your intended depth of cut.

You can apply this formula to get speed: RPM = (SFM x 12) ÷ (Tool Diameter xℼ).

Where SFM- Surface feet per minute cutting speed

The parameters can be used on feeds and speeds calculator to get the exact value needed for programming the CNC machine before commencing cutting. By using these calculated values, you are sure to eliminate all issues of overheating since you are not overworking the sitting saw blade.

Another catch to using correct cutting speed is the safety and durability of your saw. Excessive speed can lead to instantaneous dulling of your carbide slitting saw as a result of this costing you money and time. Do not forget that carbide slitting saw cost far more than the HSS slitting saw. You also must take note of the direction of rotation of your blade to place your workpiece to ensure the correct feed.

6.Heating and Coolant

Here again, we need to emphasize the sensitivity of the carbide slitting saw blade to heat. Due to small teeth and tiny gullet between teeth, heat substantially generated during cutting. In making your choice, you have to ensure flood coolant availability is guaranteed and will not destroy or attack your blade to help dissipate heat and lubricate the stick-out section of the saw.

For instance, materials like aluminum tend to get welded to their chip without proper lubrication put in place. Then the flood coolant is critical as it can penetrate the narrow slot to get the job done.

7. Types OF Milling

Milling refers to any act that involves removing chips from a material. In the case of a carbide, slitting saw, there are two forms of milling, namely:

• conventional milling: If you have rigidity in your setup is limited. The maximum cutting force is in the upwards direction towards the end of the cutting cycle. The chips generated is initially very thin and steadily increases through the cutting cycle. Avoid injury and fracture of your blade by the backlash is minimal.

• Climb Milling: When you have a rigid arbor and blade, then a climbing mill is the best fit for the job. The chip generated is often thick and thins out during the cutting cycle, while the maximum cutting force is downward at the end of the cutting cycle.


To conclude this article, you should take away this basic principle of carbide slitting saw selection, which is- “To always use the smallest thickness and diameter of saw blade alongside the largest possible arbor.” You should also take it upon yourself to look-out properly for all these enumerated factors to select the best slitting saw suitable for your need without posing any risk to yourself.
