Big Hole Drilling Ballistic or Spherocal Button Misson 40-146mm DTH Bit

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.

diameter range:105mm~127mm
DTH hammer: M40 hammer
Hole range:110mm~135mm
