  • Well Drilling Reverse Circulation RC DTH Hammer Drill Bits ...

    In RC Drilling, compressed air is pumped into a side inlet, blown down the outer shell of a dual-wall pipe and drives the hammer and bit to crush the rock. Once the air hits the drill bit, it flushes and cools the bit, and also creates a pressure different that forces the air and cuttings up the center of the drill string and into the inner tube.
