The carbide on the drill bit is shaped like a cross, the same as a tapered chisel drill bit, with different tapers and diameters. At the same time, cross drill bits are usually carbide tips, including chisels, cross-type or button types. Before the carbide is used up, the carbide can be sharpened after the carbide is worn.
The drill bit body is made of imported high-quality steel; the head is made of special alloy and processed by special welding. Drill bits are widely used in various mining projects and rock engineering.
