Atlas Copco Stopers are all-steel rock drills designed for production drilling, raise driving and roof bolting. They have a ratchet wheel rotationand and a short piston stroke for good penetration rates in soft and medium hard rock. Air blowing through the chuck when drilling, cleans the rotation chuck and lubricates the drill steel shank. The WR version has clockwise rotation and can be used for tightening or installing screen on threaded roof bolts. The BBD 46WS provides a high impact rate for good performance in soft to medium rock.
