Atlas Copco BBD 94W Pusher Leg Drill 7/8" x 4 ¼" chuck

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.
