Ingersoll Rand 2A1SA Industrial-Duty Chipping Hammer is designed for demanding chipping, scaling, demolition, and surface-preparation applications requiring greater impact energy than shorter-stroke models. Equipped with a 2" stroke, 2,300 blows per minute, and a 0.580" hex shank, this A-Series pneumatic hammer delivers controlled, high-energy impacts for concrete removal, weld cleanup, rust and scale removal, and other industrial maintenance tasks. Its industrial-duty construction is engineered to withstand continuous use in fabrication shops, foundries, construction sites, and maintenance facilities.
The 2A1SA features a swan-neck handle with an outside trigger for comfortable operation and improved tool control during extended use. A lock-spring retainer securely holds compatible 0.580" hex shank tools with an oval collar, while the replaceable piston helps simplify maintenance and support long-term serviceability. The longer stroke provides increased impact energy for heavier chipping applications while maintaining dependable pneumatic performance.
