Generally, cemented carbide drills are tools that rotate and have cutting capabilities at the tip. The commonly used drills are made of carbon tool steel, special tool steel, high-speed steel and other materials that are milled or rolled and then quenched and returned. It is made by grinding after heat treatment. However, in order to further improve its wear resistance, holes can be machined in hard materials at high speed, and cemented carbide materials are also used. There are welded drill bits and solid carbide drill bits. At present, there are drill bits that use diamond, which is harder.
