Tapered button drill bit Perfect designs, tungsten carbide and skirt steel , We provides leading strength and penetration rates for more productivity, excellent straightness and hole clean quality, get max drilling performance to save up fuel cost rate.

We can design and manufacture according to customers' samples or drawings of the diameter., buttons and flushing holes

quantity, button shape and face shape. Our button bit is made by high quality tungsten carbides and steel, through heat

treatment so that it can be used for hard rock drilling, and transmit intensive impact energy into the rock with the least
