Ingersoll Rand W3A1 Heavy-Duty Chipping Hammer is engineered for demanding demolition, scaling, and material-removal applications where increased impact energy is required. Featuring a 3" stroke, 1,725 blows per minute, and a 0.58" hex shank, this W-Series pneumatic hammer delivers powerful, controlled impacts for breaking concrete, removing weld slag, eliminating rust and mill scale, and performing heavy industrial maintenance. Its heavy-duty construction is designed for continuous operation in fabrication facilities, foundries, construction sites, and maintenance departments.
The W3A1 features a swan-neck handle with an outside trigger for comfortable handling and improved operator control during extended use. A lock-spring retainer securely holds compatible 0.58" hex shank oval-collar accessories, while the longer 3" stroke delivers greater impact energy than shorter-stroke models for more demanding chipping applications. The replaceable piston helps simplify maintenance and supports long-term serviceability in high-production environments.
