Highly efficient in medium to hard rock
Large piston diameter makes it very efficient even at low air pressure
Pusher leg control placed in back head of the rock drill
Our water flushed, pusher leg mounted rock drills are designed for driving drifts and tunnels with a small cross section. 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 percent compared to conventional integral steels. And they have three to five times longer service life.
