button bits
apered button bits are also know as cone button bits. The tapered button bits, inserted with tungsten carbide, connect with tapered rods by taper. According to button fixing processes, the tapered button bits are divided into thermal insert tapered bits and cold press tapered bits, which are widely used in mining, tunneling, anchoring and quarrying.
