Ingersoll Rand 4A1SA 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 0.58" hex shank, this A-Series pneumatic hammer delivers powerful, controlled blows for demanding material-removal tasks. Its industrial-duty construction is designed for continuous service in fabrication shops, foundries, construction sites, shipyards, and maintenance operations.
The 4A1SA utilizes a swan-neck handle with an outside trigger for comfortable operation and improved control during extended use. A lock-spring retainer securely holds compatible 0.58" hex shank oval-collar accessories, while the extended 4" stroke provides greater impact energy than shorter-stroke models for heavy chipping and demolition work. The replaceable piston supports simplified maintenance and long-term serviceability, making this hammer well suited for demanding industrial environments.
