5 Tips for Choosing the Right 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.

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.

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.
