Product Feature:

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.
