Welded Tungsten Carbide Drill Bit

Welded tungsten carbide drill bit is composed of a steel drill body and a cemented carbide shank welded to the rear of the body. Adopting tungsten carbide powder and cobalt powder as raw materials, the drill bit is fabricated by cold pressing, vacuum sintering and other processes. The surface of the hole processed by such a drill bit has a good surface finish, high dimensional accuracy and positioning accuracy, and there is no need for subsequent finishing.

Welded tungsten carbide drill bit adopts self-centering geometry blade type with small cutting force, but it can also achieve good cutting control for most workpiece. This drill bit has cooling water holes, which greatly increase the strength of the drill bit, enhance the cooling and chip removal capabilities, increase the production efficiency, and the quality of the products, and at the same time, the service life of the drill bit is also greatly improved.
