RH 656W Rock Drill

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 58 in)with Hex 22 (78") 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. This cost-efficient, entry-level rock drill offers a good balance between low air consumption and high penetration. Supplied with a T-handle, the RH 656W can also be used as a sinker drill.
