Craftsman Professional Pneumatic Air 3/8" drive Impact Wrench

Heavy duty automotive impact wrench from Craftsman Professional, manufactured by Ingersoll Rand. It has a 3/8" square drive with friction ring. I have fitted it with an automatic inline air oiler and 3/8" automotive style male quick disconnect air line coupler. It is rated at 1,500 impacts per minute (BPM or IPM), 230 ft-lb torque in forward and 260 ft-lb torque in reverse. It is a very compact and powerful (for its size) unit. And yes, it is rated at 14,500 RPM no load speed! I can't find a published flow rate, but from my memory, it requires about 3 CFM. This unit has seen light to moderate action while working on cars. I estimate I have used it for 3 years occasionally. The inline automatic oiler has been installed since it was new and I always used a high quality oil. It is in perfect working order and comes with what you see in the photos.
