Tapered Button Bits

Tapered Button Bits

Tapered button bits are mainly used with pneumatic rock drill and tapered drill rod, and it conducts drilling operations through the connection of the taper on the drill bit and drill rod. The tapered button bits are suitable for hard rock drilling and are mainly used in mine secondary crushing, bolting, drifting and other fields. As an upgraded product of the chisel drill bits and cross drill bits, the tapered button bits have good drilling effect and long service life due to the tungsten carbide tips and the hot-plated skirts. Conventional taper angles for tapered drill bits are 7°, 11° and 12°.
