What to Look for Before You Buy?

Going through the reviews is not going to be enough if you want something that high in performance and worth the money. For that, a couple of factors should be in your consideration as well. Wondering what factors are we actually talking about? Well, those areas stated below


The first thing that should be in your consideration is the size. Usually, most of the brands are going to offer a set of many. Those will contain at least four different sizes of bits. There are some that will offer as many as ten differently-sized bits in the same package.

Nevertheless, some of the manufacturers are going to sell these in a specific size. For both cases, you should check whether the size that you are planning to work with is available or not. If you happen to get something small, you would need to make multiple cuts, which are not that high in accuracy. Check our latest article about how to determine drill bit size for wall anchor.


Other than the size, you need to also consider the compatible depth of the bits. In this case, check the thickness of the tiles that you plan to work with. For instance, if you are working with something that is ¼ inches thick, you would need to get the bits that can go through ½ inches.

Construction Material

One of the important factors for drill bits is the construction materials. Usually, these are going to be of steel. However, the quality of the steel will not be the same for each of the models. Some might utilize low-quality steel, while some will be of high-quality steel.

Our recommendation would be to get high-quality ones. Those would have a higher level of durability, which will eventually offer you extended use. They would also be capable of resisting wearing.


Most of these will have one common coating, which is the diamond coating. This diamond coating will ensure that the tips can resist wearing exceptionally well. Additionally, they will enhance the overall lifespan and the performance of the tips.
On the other hand, some of the brands will go one step further and coat their bits with nickel. That will make them resistant to corrosion, which will eventually increase the overall lifespan of the units.


Last but not least, the sharpness should be in your consideration too. If the tips are not that sharp, going through dense materials like porcelain will become tough. In addition to that, the sharper the tips, the cleaner the cuts are going to be. So, you should pick the sharp ones.
