Regular price $469.95 Sale price $737.00

Ingersoll Rand Industrial Duty (A Series) Air Chipping Hammer model 4A1SA.  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 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 4A2SA which has the same specifications except it has the round shank required to satisfy this need.

If your application requires a heavier duty version of this tool, check out the IR Model W4A1 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.

Features

  • Grooved barrel, lock spring retainer

  • Swan neck handle

  • Outside trigger

  • Time tested valve durability

  • Replaceable piston

  • Long nozzle for extra life

  • Threaded barrel and rubber buffered retainer
