Ingersoll Rand 1A2SA Industrial-Duty Chipping Hammer is designed for high-frequency chipping, scaling, and surface-preparation applications in construction, fabrication, foundry, and industrial maintenance environments. Featuring a 1" stroke, 2,500 blows per minute, and a 0.680" round shank, this A-Series pneumatic hammer delivers rapid, controlled impacts for removing concrete, weld slag, rust, scale, and other surface materials. Its industrial-duty construction is built for continuous service while providing dependable performance in repetitive material-removal operations.
The 1A2SA incorporates a swan-neck handle with an outside trigger for comfortable handling and precise operator control. A lock-spring retainer securely holds compatible 0.680" round shank oval-collar accessories, while the replaceable piston helps simplify maintenance and support long-term serviceability. The combination of a short stroke and high blow rate makes this model well suited for applications requiring fast, controlled chipping rather than heavy demolition.
