Description
CHISEL BITS, which is one the most important type of drill bits, Chisel bits with one piece of are hard alloy only, and usually matched to the tapered drill rods. And they are always used in mining, tunneling, pneumatic drilling, and other projects. and famous for its simple manufacturing process, low cost, easily repeat grinding, reliable operation, and strong adaptability to the properties of the rock mass.
