Ingersoll Rand 2132G 1/2-Inch Edge Series Air Impact tool, Red, super quiet, read the reviews this wrench is known to be the quietest ever! And 600 ft lbs!
I use it for lug nuts on my truck, only selling to recoop some toolbox space and money I spent on a new $500 battery unit I bought with higher torque for my heavy equipment. Oiled before use each time. Some of the grease will come off I haven't attempted to clean it yet as I still use it occasionally.
Again, nice for being super quiet, not like the old loud ones means good for your hearing or if you have neighbors.
Paid close to $300 when new.
Will trade for something Milwaukee tool or ??? Email me and ask!
