ATLAS COPCO Pnuematic Rock drill BBD94W

Atlas Copco water flushed, pusher leg mounted rock drills are designed for driving drifts and tunnels with a small cross section. These well-proven rock drills are recognized for their high performance and reliability. They are intended for use for hole diameter range of 27 to 41 mm (1-1 5/8 in)with Hex 22 (7/8″) rotation shank as a standard. When used with Atlas Copco tapered button bits, penetration rate will improve some 25-50% compared to conventional integral steels and have three to five times longer service life. With its short stroke and high impact rate, the BBD 94 is ideal for working softer rock. This drill is comparatively short and provides an outstanding power-to-weight ratio thanks to its ratchetwheel rotation percussion mechanism.
