IR3.5 90mm 105mm Blast Hole DTH Drill Bits Good Wear Resistance
|
...Blast Hole DTH Drill Bits Good Wear Resistance 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......
