Ingersoll Rand Chipping Hammer Round Shank Oval Collar - W4A2 - 4-inch stroke
The Ingersoll Rand Heavy Duty Air Chipping Hammer model W4A2 (W Series) has the same tough specifications as the "A" series units, but with a heavy duty front end featuring a threaded barrel and rubber buffered retainer for increased steel and retainer life. This heavy duty class tool is widely used throughout industry and construction work and is renowned for its valve life and handle durability. It is ideal for light demolition work, bridge decking, concrete surface preparation, metal removal, form stripping, and many other applications. This series model has a 4" stroke. This model is the largest chipping hammer offered in the series which means it will hit with the most power. At just under 18 pounds it's still light enough to maneuver and provide the necessary power to get the job done. This model comes with a round shank which allows your bit to rotate or turn in the tool while you are pressed against your work. You will use bits that are designed for the round bushing and oval collar retainer in this style tool. This allows your bit to move freely and accommodate the surface you are working on such as a curved surface or rock. We have a great selection of steel bit accessory points, chisels, bushing tools, and ground rod drivers here that fit this style (round shank / oval collar) chipping hammer.
If you need your bit to remain in the same exact position you place it in the tool please see IR Model W4A1 which has the same specifications except it has the hex shank allowing you to chip straight lines out on surfaces.
If your job doesn't require this heavy duty model, check out the durable IR Model 4A2SA (Industrial Duty) which has the same specifications (less the heavy duty front end) as this tool has a more economical price point.
