12 Degree Carbide Tungsten Tapered Button Bit Small Hole Rock Drilling Tools
Product Description:
Tapered button bit,also known as taper drill bit, is a drilling tool which has a wide applications such as mines, tunnels, and construction engineering. Its design is mainly for drilling holes in rock drilling and blasting operations, usually in conjunction with handheld or mechanical rock drills.
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°.
Features:
-
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.
-
Impact resistance: The button bits need to withstand high-intensity impact and vibration during rock drilling. Therefore,their design must have sufficient impact resistance to ensure stability in high load working environment.
