The Drill Bits are made from grade hard alloy and
special steel, generally matched with the light-duty rock drill, to drill the
rock hole within diameter of 50mm. The drill tools are used in
metallurgy mine, geological exploration, water conservancy construction,
electricity, traffic, tunnel, quarry, national defence stone project etc.Rill bits are cutting tools used to create cylindrical
holes, almost always of circular cross-section. Bits are held in a tool
called drill, which rotates them and provides torque and axial force to create
