    I've got less money tied up in my air impact gun, air hose, impact sockets, fittings, air drill, air cutoff tool, lock-on tire chuck, drill bits, air powered grease gun, and a week's worth of meals. For as often as they are needed on the road, I just don't see the point in spending an arm and a leg for a tool that will only work if you're vigilant about keeping the batteries charged up and ready to go...especially when the air system is right there to be tapped into.

    I worked at a place once that had the Lincoln battery powered grease gun and a spare battery. I'd STILL wind up using a manual squeeze gun most of the time because the batteries weren't charged or they wouldn't last. When a tool is rarely used, and an unplanned need for it arises, it needs to work. My experience with battery powered equipment has been less than acceptable in that regard. I'll stick to air, because it works. Besides, if I'm not at home the truck is running anyway...and if I am home, I've got an 80 gallon compressor in the garage.

    I've been trying to setup an air line off my tanks on the cheap. What size quick connect do you have coming off your air tank? My truck has 1/4 inch NPT threaded bleeder valves already in them. I bought a 1/4 inch quick connect and shutoff but didn't think a 1/4 inch line would give an impact the volume it needs. I wish my air tanks already were tapped with 3/8 inch threaded bleeders. If I used a converter coupler 1/4 to 3/8 inch and used the industrial 3/8 inch quick connect would that get more volume to the impact gun?? It's still gotta go through that little 1/4 inch threaded hole. BUT! The 3/8 inch air line I saw came with 1/4 inch quick connectors??? What size quick connect is coming off your impact gun?

    Can you run an air impact to say remove the lug nuts on a wheel with a 3/8 inch airline with 1/4 inch quick connects on both ends? I'm so confused.

    Don't count on it. Even if you had a hand impact rated at 150psi that line would never push that much volume in time to produce the torque needed to break 10 lugs.
    A breaker bar and old fashioned work would be harder, but in a bind could work. A torque multiplier wrench would still be even better!
    There's a reason tire shops use those big guns, cause it gets the job done and even then ya still gotta hammer on it

    I've never had the patience to run an impact off my truck. Uses to much air and takes to long to build back up

    Exactly! Tanks are too small to push enough air for serious continuous work.
    I still use my air tools though!:biggrin_25519:

    It's all about psi. The big compressors we used to tow around were 185 psi so you could run two or three rivet busters off that. Rivet buster is an air powered chipping tool- weighs about 35 pounds, we used them to cut off concrete pilings. Think they were originally designed with a chisel tip to cut off the big rivet heads on bridges and ships without marring the parent steel. They work outstanding on concrete though.

    Anyway I'm not sure how much psi the truck's air compressor governor puts out, certainly not even close to 90 psi. I supposed you could plumb a big tank in between the truck and the impact wrench you want to use, just have to wait for the big tank to fill up. I think it would be quickly depleted and take half a day to get ten lugnuts off.

    My trailer tires are ready for a rotation again, TA shop charges $10 bucks a wheel. I'd sure like to do it myself, with the wheels off, clean them up real good and touch them up with the white paint to make 'em look purty.

    I didn't pay attention to all models, but i noticed today, this model I got is 2763-22, 1/2 ",1100ft-lbs nut-busting and 700 ft-lbs fastening torque.
    They have this model http://www.milwaukeetool.com/power-tools/cordless/2764-22. 3/4" model bit more powerful model 2764-22, 3/4 " 1200 ft-lbs nut -busting and 750ft-lbs fastening torque. Anyway I won't change it because I have a set of good 1/2 " sockets.
    I found a video in action working truck lugnuts;

    This is impact driver not wrench,;
    delivers 1,450 inch-lbs = 120 ft-lbs !!! you need around 500 ft-lbs of torque to remove truck wheels lug nuts;
    The terms are confusing, I watched this video explains the difference ,, impact drivers work for smaller applications but are not designed for high toques; ;
