drill bits for water well drilling

D Miningwell dth hammer is connected with dth drill bit for drilling engineering. D Miningwell uses high-quality steel, alloy steel as raw materials, adopts special heat treatment process and advanced cemented carbide inserting technology, so that dth hammers bits can function well even on hard rock formations, and at the same time save energy.

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.
