The shortest 1" drive air impact wrench is also one of the most powerful. It combines a very compact size with high power output, making it ideal for tire changing, spring work, pinion nut and tractor pad removal, and shock work.  Impressive power-to-size ratio: light, at just a little more than 12 lbs. and just under 9" long. The Jumbo Hammer mechanism delivers up to 1,200 ft lbs. of torque smoothly, with less vibration. Built-in Pressure-Feed Lube System for longer service life. Dead handle makes it easy to handle the tool.  Features a 3/8" air inlet.
