Description
Thread button bits 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.
This type of bit is well known for its wear resistance on medium-hard to hard rock formations.Featuring spherical tungsten carbide inserts that is known to have strong configuration against carbide fracture
