    Default Impact Wrench question?

    There is a great deal at Canadian Tire right now. Mastercraft impact wrench: 7.5 Amp, 240ft lbs max torque, 2200/2700 BPM. Reg $179.99 sale $59.99
    I wonder if this tool is strong enough to handle the lug nuts on a car for wheel changes? I do own a compressor and was going to buy an air one but wonder if this enough? I torque my lugs to 110 lbs and this is rated to 240 so should be more than enough I would think?

    I have not used this exact wrench but used another brand similar specs and it worked good. I am not a fan of using a impact to install lug nuts unless your just spinning them tight then use a torque wrench to set them.
    At that price I would say it's a deal hard to pass up if you can use it

    Yep! Nothing worse than some kid at CT torqueing your nuts so tight that you can't get them off when back in the boonies.
    Some CTC tools scare me but I did recently buy a reciprocating saw that I'm more than happy with--quality ways that is!
    I'd say that if you intend to use the wrench every blue moon or so, then it should be a safe deal.

    I have a 3 amp CT impact and it was not quite strong enough under all conditions. I suspect that the 7.5 amp version would do the trick. If you are patient though, you can buy the 100 piece air tool kit for $100, which includes a decent air impact gun, plus three other air tools. You would have to make sure your compressor has enough output though.

    As has been said, do not torque the lug nuts with an impact wrench. You'll be sorry.

    I use an electric impact for seasonal tire changes, brake jobs, etc to remove the lugs and suspension components. More than enough power and works great.
    I cannot dial in a torque setting on my older model so I use a manual torque wrench for re-installation of the lugs which is typically at 110 ft/lbs and also prevents warping the rotors.
    Don't forget to torque the lugs in a star pattern and check them again after 100 kms or so.

    I'm on my second electric impact gun. I would not be without one, I carry one on moose hunts with a small genny. The first one was wore out after 20 years of use. Even with air in your shop I would purchase this impact at that price

    I have a Makita battery operated impact gun and I have used it many times for just about anything. Lots of power for almost anything you need, without having to plug it in. IMO a more versatile option.

    I will grab it today. I also have a proper torque wrench and check my torque periodically.

    I have one. I use it regularly and it does an excellent job. It sure saves on the wrist. Be sure to check your lugs with a proper torque wrench,though. Sometimes,the gun can run a bit over. It's a good unit.
