i have a hardly ever used impact wrench 1/2 inch drive 6" long anvil it turns with air but lack power if you handy this may be a good impact. i have 3 and i'm cleaning house. maybe parts? anyway it says 500 ft pounds on it so maybe some oil and it will be good. like i say i have 3 and don't need it. stop out and get it while it lasts. thanks
