QL120-349mm Rock Drilling Equipment Tools Dth Drilling Button Bits
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.
• Underground mining • High grade tungsten carbide inserts
