2,300 BPM with a 3.75 in. stroke delivers fast impact for bolt cutting, driving pressed pins, separating ball joints, and other heavy-duty air hammer work. Long barrel design helps technicians reach suspension, front-end, and tight-access service points where a shorter air hammer can be harder to position. Quick-Change Chuck Retainer accepts standard 0.401 in. shank chisels for faster accessory changes. Patented Damping System and Active Air Spring Technology help reduce vibration and absorb shock to minimize fatigue during longer jobs.
