Medium-Duty Air Hammer Kit

The Chicago Pneumatic CP7111K is a medium-duty pneumatic hammer kit built for automotive and industrial repair tasks. It includes the hammer, an oiler, a quick-change retainer and a selection of chisels and punches. The kit suits technicians who need a complete air-powered striking set for panel cutting, spot-weld splitting and edging work.

Sustained Operation at 3,000 Blows Per Minute

The tool delivers 3,000 blows per minute with a 2 5/8 in stroke length while consuming 25 cfm of air. The 1/4 in NPT female inlet feeds a steady supply to maintain that rate during extended use. A round 0.401 in shank and quick-change retainer keep bits secure under continuous vibration. The included oiler helps preserve internal components over long sessions.

0.401 Inch Round Shank Compatibility

The single specification that decides fit is the 0.401 in round shank with quick-change retainer. Only bits matching that shank diameter and collar shape will lock correctly. Buyers whose existing chisels use a different shank size or retainer style cannot use them with this hammer without an adapter.
