254mm High Pressure DTH Drill Bits In Overburden And Water Well Drilling Project
SD8 254mm DTH Drill Bit High Pressure Bits In Overburden And Water Well Drilling Project
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.
