Milwaukee 1/2" Electric Impact Wrench with Rocker Switch
My initial inclination was to give Milwaukee the number one spot on this list, just due to their quality and ruggedness. Impact wrenches receive a lot of hard usage and I have a lot of confidence in Milwaukee's tools to handle that, but the specs pushed it out of that top spot. While this is an excellent impact wrench, it's not quite as powerful as the one's we've already looked at. This wrench is rated at 300 ft. lbs. It's motor runs at 1800 RPM and the impact hammer provides 2600 IPM. However, I have to say that from my experience with Milwaukee's tools, I'd say it might still outperform one of the others. At 6.0 pounds, it appears to be lighter than the others (although they don't all give their weight). The anvil on this one uses a friction ring retention system and it has a rocker switch trigger.
