An RC drill rig, short for Reverse Circulation drill rig, is a specialized drilling machine that uses compressed air to lift rock cuttings from the drill hole through a reverse air flow system. Unlike traditional drilling methods, the RC drill rig employs a dual-walled drill pipe: air flows down the outer pipe and cuttings are returned up through the inner pipe, ensuring rapid and uncontaminated sample retrieval.
