RC Hammer Drilling Shark

RC Hammer Drilling Shank

An RC (Reverse Circulation) Hammer Drilling Shank is a specialized down-the-hole (DTH) drilling hammer and bit system used primarily for mineral exploration, grade-control drilling, geological sampling, quarrying and mining. Unlike conventional DTH drilling, the RC system returns drill cuttings and samples through an inner tube, helping reduce sample contamination and allowing continuous collection of representative rock samples.
