The Tapered Button Bit is an essential component in pneumatic rock drills and tapered drill rods, which conduct drilling operations through the connection of the taper on the drill bit and drill rod. These bits are designed for hard rock drilling and are mainly used in mine secondary crushing, bolting, drifting, and other related fields.
The Tapered Button Bits are an upgraded version of the chisel drill bits and cross drill bits. Thanks to the tungsten carbide tips and the hot-plated skirts, the tapered button bits provide a good drilling effect and have a long service life. With their excellent features, these bits offer a reliable solution for all your drilling needs.
Conventional taper angles for tapered drill bits come in three standard options: 7°, 11°, and 12°. The proper angle for your drilling activities will depend on the type of rock you are drilling and the specific application in which you will be using the bit.
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.
