High Pressure DTH380 Length 1550mm Thread API 4 1/2" Down Hole Hammer Bit
|
...Hole Hammer Bit / DTH380 Length 1550mm Thread API 4 1/2" 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......
