Ingersoll Rand Chipping Hammer Hex Shank Oval Collar - W4A1 - 4-inch stroke
The Ingersoll Rand Heavy Duty Air Chipping Hammer model W4A1 (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 hex shank which means your bit will not rotate in the tool. You will use bits that are designed for the hex bushing and oval collar retainer in this style tool. The bit will remain in the same exact position you place it in the tool. This will allow you to chip straight lines out on surfaces. We have a great selection of steel bit accessory points, chisels, bushing tools, and ground rod drivers here that fit this style (hex shank / oval collar) chipping hammer.
If you need your bit to move freely to accommodate the surface you are working on (like a curved surface or rock), please see the IR Model W4A2 which has the same specifications except it has the round shank required to satisfy this need.
If your job doesn't require this heavy duty model, check out the durable IR Model 4A1SA (Industrial Duty) which has the same specifications (less the heavy duty front end) as this tool has a more economical price point.
