Atlas Copco – BBC34W – Jack Leg 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 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. The BBC 34 offers exceptional penetration rates in medium to hard rock, thanks to its long stroke and high impact energy.
