Feature of the taper button bit:

Premium designs and steel and premium tungsten carbide inserts, offers industry leading strength and penetration rates for more productivity, excellent straightness and hole clean quality, get max drilling performance for rock drill with long life to save up fuel cost rate.

We can design and manufacture according to customers' samples or drawings of the Bit Dia., No. of air / water holes, carbide button shape and the face shape. Our button bit is made with high quality of best quality alloy steel bar and tungsten carbides, through heat treatment so that it can withstand the toughest rock drilling demands, and transmit intensive impact energy into the rock with the least possible loss of energy. Comparing with tapered chisel bits and tapered cross bits, button bits has higher technology, much longer primary drilling time and higher drilling efficiency. According to the tungsten carbide insert, tapered button bits can be divided into the types of hemispherical, conical and parabolic button, etc.
