The Chicago Pneumatic CP 0069 is the heaviest sinker rock drill in the CP range a 60 lb class tool whose extra mass turns a slower 1,920 BPM into maximum energy per blow for dense-rock holes. Quarry, foundation and construction crews run it for pedestal-style downward drilling: anchor bolts, foundation pins, secondary breaking and small-diameter blast holes, at the top end of our sinker drills range.

Choose the 7/8 x 4-1/4 or 1 x 4-1/4 in. hex chuck and matching drill steel. Air demand is 130 CFM at 90 PSI through a 3/4 in.
