Ingersoll Rand 4A2SA Industrial-Duty Chipping Hammer is built for heavy-duty demolition, concrete removal, scaling, and industrial maintenance applications where maximum impact energy is required. Featuring a 4" stroke, 1,480 blows per minute, and a 0.68" round shank, this A-Series pneumatic hammer delivers powerful, controlled blows for demanding material-removal tasks. Its industrial-duty construction is designed for continuous operation in fabrication shops, foundries, construction sites, shipyards, and industrial maintenance facilities.
The 4A2SA incorporates a swan-neck handle with an outside trigger for comfortable operation and enhanced operator control during extended use. A lock-spring retainer securely holds compatible 0.68" round shank oval-collar accessories, while the extended 4" stroke provides greater impact energy than shorter-stroke models for challenging chipping and demolition applications. The replaceable piston simplifies maintenance and supports long-term serviceability in demanding industrial environments.
