Best of Grade Control Drilling Method PR40 RE040 140mm RC Drill Bits For RC Drilling
RC is a drilling method widely used around the world. It produces samples of high quality and reliability.
Reverse circulation (RC) drilling uses a bit attached to a down-hole hammer to produce a hole. Unlike diamond drilling, RC drilling produces samples of rock cuttings rather than a sample of rock core. The down-hole hammer is powered by compressed air, which also acts as the medium bringing the drill cuttings up to surface.
