Fast Drilling Speed 8 Inch DHD380-290mm DTH Bit For Plast Hole Drilling


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.
