BR2 76mm Hammer Dth Drill Bits Water Hole Deep Drilling
BR2 76mm Hammer Bits Water Hole Deep Drilling DTH Drill Bits Description DTH bit is the tool cutting rocks, and subject to severe stress from the striking piston as well as from the abrasive cuttings passing the bit at high velocity. When selecting the right bit for optimum performance you have to balance penetration against bit life. On occasion you can successfully sacrifice bit life for penetration, remember the rule of thumb that states that a 10% increase in penetration

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. DTH bits are paired with their corresponding hammers (by drilling hole diameter and spline configuration). Customers
