The Atlas Copco BBC 16W is a 60 lb class pneumatic stoper rock drill for upward-hole work underground drift driving, rock-bolt holes in mine and tunnel roofs, and overhead anchor drilling. A 2-3/4 in. bore and 2-1/8 in. stroke produce 2,340 BPM through a 7/8 x 4-1/4 in. hex chuck, backed by the parts pedigree of Atlas Copco rock drills.

Overhead drilling is leg-supported work: pair the drill with the pusher leg attachment for BBC series rock drills so the leg, not the operator, carries the 63 lb tool into the back. Air demand is 147 CFM at 90 PSI through a 3/4 in. NPT inlet. For horizontal and downward alternatives in the same weight class, the buyer’s guide to rock drills walks through configurations, and the wider rock drill selection covers every class we stock.
