API 76mm 2 3/8 Water Well Drill Drilling Pipe DTH Drill Rod

API 76mm 2 3/8 Water Well Drill Drilling Pipe DTH Drill Rod

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 drilling can do. This is possible with the use of DTH Pipes and DTH Subs.
