Product Description
Threaded/Tapered (taper 7, 12degree) chisel/cross bits are mostly used for hand-held rock drill. We make them by alloy steel by forging and select suitable tungsten carbide insert as per customers requests in accordance with their local rock conditions,such as for, limestone, marble, granite etc.
The chisel bit is made from grade hard alloy and special steel, generally matched with the light-duty rock drill, to drill hole within diameter of 50mm.
It is widely used in metallurgy mine, geological exploration, water conservancy construction, electricity, traffic, tunnel, quarry, national defence stone project etc.
