Underground Mining DTH Drilling Tools Drill Sub / DTH Adapter
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.
