2 Inch Mining DTH Drilling Tools , F Thread 50-60mm DTH Drill Pipe
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 drilling can do. This is possible with the use
of DTH Pipes and DTH Subs
