The Rock Drilling Bits are made from high-grade hard alloy and special steel, generally matched with light-duty rock drills, to drill rock holes within a diameter of 50mm. These drilling tools are widely used in metallurgy mines, geological exploration, water conservancy construction, electricity, traffic, tunnels, quarries, and national defense stone projects.
