Hard Rock Drill Bits and High Speed DTH Hammers

D Miningwell’s down-the-hole drill bits are made of alloy steel and advanced heat-treated high-quality alloy steel to ensure good drilling performance and long service life. Widely used by customers all over the world.

D Miningwell down-the-hole hammer drill bits are made of carbide inserts and steel. Widely used in water well drilling and protection of hard rock formations. In the past 30 years, we have exported this drill bit to many countries with good feedback. You are welcome to contact us if you need. We can supply all series of drilling equipment and drilling tools.

D Miningwell down-the-hole drills use 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. The teeth and teeth are not easy to fall out, so the impact energy is concentrated on the rock to achieve high-efficiency driving.
