Rock Drills

Rock Drills

With only two parts moving during operation, a non-corrosive automatic valve, less radial piston movement and high-tech alloys, our drills do not require special rock drill oil. Under normal operating conditions, oil carry-over from the compressor combined with moisture in the air will provide sufficient lubrication.
