...API Reg Thread DTH Drill Pipe Length 1000mm - 6000mm 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 drilling enables drillers to reach hole depths that are double of what top hammer
