Are there impact wrenches that run off the power outlet of a car? Don't have a garage and was wondering if an electric one exist but uses the aux power outlet in cars.

 

There are electric ones that use 110v

you not gonna get much of an impact from a 12v battery from the car.

Makita actually makes a 18v cordless impact wrench and it's still only good for small jobs on the car.


If you looking for a powerful electric one, get the 110v that you can plug in house or something (with extension cord)

 

So much for that. I basically need something to loosen very tight lug nuts. The factory lug wrench is not up to par. Dealer tightened nuts too damn tight.

 

you just need a breaker bar.

 

get your self a breaker bar

 

brilliant minds think alike

 

Thanks.

 

There are battery powered Snap On Drills that have more than enough power to remove your lugs. I never used it on anything bolted down more than ~85 lbs so i couldnt tell you beyond that. Check them out tho.

Edit: If you only need this for a rare occassion- pick up a breaker bar like these guys said.

 

Either a breaker bar, or get a cordless Impact. DeWalt sells a really good one.

 

i hand tighten my lug nuts then use a torque wrench.

Will never need a breaker bar, will never overtighten, and never messes up your wheels!

 

actually call me a noob if you guys want, but i've messed up 2 studs already by using an impact wrench, I always just take the extra time to hand tighten now LOL

 

I use impacts merely for loosening. It's hard to gauge if a nut binds or it's threaded incorrectly when you're using an impact to put them on.
