Tapered Cross Bits for quarrying, mining, tunneling
Carbides shapes are cross type on the rock drill bits,the same as taper chisel bits, they have different taper degree and diameters.
Cross bits are Usually are carbide tips, including chisel, cross or button types, before carbides run out, carbides can be grind to be sharper when carbides are wear out.
Drill bit body is made of high quality steel imports; the head is made of special alloy through special welding processing.
This drill bit is widely used in all kinds of mining engineering and rock engineering.
