Detailed Product Description

DHD Shank DTH Bit DHD380-203mm DTH Bit For Pile Foundation Engineering

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.
