Button Bits, Cross Bits,tungsten Chisel bits,Threaded/Tapered (taper 7, 12degree) chisel/cross bits are mostly used for hand-held rock drill.

The chisel bit is made from grade hard alloy and special steel, generally matched with the light-duty rock drill, to drill hole within dimeter of 50mm.
It is widely used in metallurgy mine, geological exploration, water conservancy construction, electricity, traffic, tunnel, quarry, national defence stone project etc.
