...Heavy Weight Drill Pipe for DTH Rock Drilling Product description: In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length. DTH drill pipes are widely used in mining,geothermal and all kinds of DTH rock drilling
