Tapered button bit is 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°.
Tapered interface: The interface part of the drill bit is conical, which allows the drill bit connect with drill rod firmly . It greatly reduce looseness during the drilling process.
High strength materials: Since the drill bit needs to drill holes in hard rock, it usually use high-strength alloy steel. Moreover,heat-treated treatment of drill bits will improve wear resistance and strength.
