Milwaukee 2767-20 M18 FUEL High Torque 1/2" Impact Wrench with Friction Ring - Amazon.com

Power means torque and it holds up to the claim. Battery life is as expected, it's a bit heavy if you were to use it multiple hrs...

Lots of Ugga-duggas. Fast, easier to carry around and easier to use than my pneumatics. Worth the money.

My oldest son has this same driver and so when my Birthday came around, I just had to have one. It removes nuts quickly and has the power to do just about ANY industrial type job you can set it to do. A nut or bolt that is frozen is NO match for this Big Dog! Performs flawlessly and is VERY heavy duty! I highly recommend this unit!!
