D Miningwell dth bit uses high-quality steel and cemented carbide as raw materials. After a special heat treatment process, the hardness of the button bit is achieved under rock excavation, and the energy loss in the transmission process is reduced, and the teeth are evenly stressed , Not easy to fall off the teeth and teeth, so the impact energy is concentrated on the rock to achieve high-efficiency driving.
