The Atlas Copco BBD 12 is a 30 lb class handheld pneumatic rock drill for anchor-hole drilling, foundation pins, quarry bench work and rock bolting. It runs 2,5202,580 BPM with 220 RPM rotation on 4751 CFM at 90 PSI, and D-handle and T-handle builds with or without a muffler let crews match the drill to jobsite noise rules. It anchors the compact end of the Atlas Copco rock drill lineup.
The 3/4 x 4-1/4 in. or 7/8 x 4-1/4 in. chuck takes standard hex drill steel, and modest air demand keeps it happy on contractor compressors. Percussion tools live longest on lubricated air, so put an oiler and rock drill oil in the circuit from day one.
