Question about cordless impact drills

[jamnolfin]

How powerful can these things be, will they change a tire? Take off lugs and put them on with at least a 120 pounds torque? I'm looking at the Dewalt 20 volt since I already have 20 volt batteries. Here is the one I'm looking at. I'm buying one regardless but I would like to get one that deals with RV tires while I'm traveling. I have good sams coverage, last time I had a flat on RV I had to wait 2 hours on the side of the road on I-10. I'm not into that.

One of answers in the Q and A:

"I use mine with the dcb207 battery pack that came with a drill/charger kit. It does work but I'm disappointed with the torque. I bought this driver to remove lug nuts and it's not really up to the task. I need to use the cross bar wrench on at least one nut on each wheel and when i tighten the nuts max torque seems to be between 60 and 70 ft/lbs."

Apparently it is advertised as capable of 150 ft lbs of torque. That's a lot for even an air driven impact wrench.

We use 18v Dewalt on our race cars almost exclusively. Not sure of the exact torque rating but they torque hard enough to hold up for many laps, sideways on a beat up dirt track. Fingers crossed we've never had a lug nut back off. I've used them on vehicles and sometimes have to use a lug wrench/pull bar to break loose stubborn nuts.

Why wouldn't you just get one that hooks up to an air compressor that you could plug into your generator? It's been my experience that unless you use a battery powered tool on a regular basis you're better off get one that plugs into a source...

Its not a motor home and I don't carry my generator

I've read the reviews but was wanting to hear from one of you guys. You can buy that Dewalt for close to the same price as a long wrench. Dang tools are expensive.

Wow, that's good to know.

Is this for a 5th wheel or bumper pull? My motorhome wheels take 450 ft lbs.
