Ingersoll Rand Chipping Hammer Round Shank Oval Collar - 4A2SA - 4-inch stroke
Ingersoll Rand Industrial Duty (A Series) Air Chipping Hammer model 4A2SA. This classic 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 4A1SA which has the same specifications except it has the hex shank allowing you to chip straight lines out on surfaces.
If your application requires a heavier duty version of this tool, check out the IR Model W4A2 which has the same specifications as this tool except it has a heavy duty front end featuring a threaded barrel and rubber buffered retainer for increased steel and retainer life.
Grooved barrel, lock spring retainer
Swan neck handle
Time tested valve durability
Long nozzle for extra life
Threaded barrel and rubber buffered retainer
