Impact Wrench Question?

[1172scorp]

Do any of you guys use a cordless impact wrench? If so what brand and model? I bought one from harbor freight (Bauer) brand. It struggles to get the lug nuts of at 100 ft lbs. It's rated at 450 ft lbs.

I don't use one on my Challenger until after I've used a breaker bar to get the lugs loose...way loose. I just use my cordless impact wrench to spin the lugs off or use my cordless drill. I purchased a Craftsman 1/2" 18.2v 250 pound cordless impact wrench. That joker is super strong and fast!! I've had it for only a year, though, but it has worked perfectly!

I have a Milwaukee corded electric impact. Works like a champ.
