Perfect designs, tungsten carbide and skirt steel. We provide leading strength and penetration rates for more productivity, excellent straightness and hole clean quality, getting 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 of 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 possible loss of energy.
Comparing with tapered chisel bits and tapered cross bits, button bits have higher technology, much longer primary drilling time, and higher drilling efficiency. According to the buttons, tapered button bits can be divided into the types of Dome, Ballistic, etc.
We can make all sizes and shapes according to your request!
