Drill Bit Materials

Drill bits can be made out of different materials. Every one of these materials has pros and cons, and it is on you to choose the one you need.

Steel Bits

These bits are great for softwood, and they are also cheap. If you use them on the hardwood, they will quickly go dull, and they even might break.

High-Speed Steel Bits

These are harder than the previous ones, and they will stay sharper for a more extended period. Also, this type of drill bits is highly resistant to torsion and heat.

Titanium Coated Bits

They are a bit more expensive than the high-speed ones, but they will also stay sharp longer because they are made out of more durable material.

Carbide Tipped

These are even more expensive than the titanium ones. With money comes better quality; therefore, these will stay sharp the longest.

Cobalt Bits

These are special bits made for more durable materials which often cause a heated build up because of friction, and they can dissipate the heat which means that they can stay durable for more extended periods. They are best used for drilling through materials like stainless steel and other metals.

Drilling Tips

If you are doing general drilling, use a bit that has a twist. The best one is a high-speed bit. Masonry bits that drill at lower speeds are best when you are drilling plaster, brick, slate or concrete. The spear point drill bit that works at low speed is best when you are drilling holes in glass or tile.

If you need larger holes, then you should use a hole saw. When using this one, be sure that your drill is powerful enough to handle the extra force or else your motor will burn out. When drilling holes in metal, be sure to use a step bit at low speeds.

The drill bit is the most crucial part of the drill as it is the thing that makes the bore or cut in your work. Therefore, we would suggest that you spend a little more money so that you can get a better quality one. It will pay off in the long run, and you will also be less frustrated when using it.
