Sansung rock drilling thread button bits are widely used in all kinds of mining, drilling, quarrying, engineering, construction, water well drilling, oil exploring industries etc.
The thread button bits are made with high quality of best quality alloy steel bar and tungsten carbides with superior wear resistance and impact toughness superior, 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.
