Rated 4.8 out of 5 by 23 reviewers.
Rated 5.0 out of 5.0 by HIGH TORQUE IMPACT WRENCH This wrench is everything it was said to be and more!. I took it out of the box and tried it on my lug nuts of my old rusty car and the lugs came off like a hot knife through butter. This was on 1/2 battery power!. This is one tool to have in your vehichle for those unexpected flats. Would buy it again in a heart beat. May 29, 2010
Rated 5.0 out of 5.0 by Milwaukee Is A Frankenstein Factory! This is my second Milwaukee cordless power tool, and I am a fan for life. My first is a M12 hammer drill, now this. I work with junk cars, the oldest, rustiest, most neglected vehicles on the planet. The M18 1/2in impact breaks rust on lugs like a hot knife through butter. If there's a better brand out there, God bless 'em. I'm buying Milwaukee! (This is a real review; probably my first ever) August 14, 2013
Rated 5.0 out of 5.0 by Great for the tradesman In my profession, I need a tool that will stand up to the rigors of constant use. You will not find a better impact for durability March 6, 2012
Rated 5.0 out of 5.0 by They weren't kidding when they said High Torque Received the tool and put it to the test on some heavily rusted 5/8" bolts without using any penetrating oil or break free, if it didn't break them loose, it broke them. I currently own two brand name impacts (corded & cordless), they're not bad, but this 1/2" Milwaukee impact is by far more superior especially in power which makes me one very happy camper.

Rated 5.0 out of 5.0 by Doesn't Get much better Purchased this wrench to use for car projects and changing tires at track events. At least 3 other colleagues used this wrench during a weekend event. It performed perfectly each time, every time. The charge held by the battery is amazing. After going through 3 cheapie cordless impact wrenches, I finally spent the money on a good one. It was worth the expense. September 20, 2011
Rated 5.0 out of 5.0 by Out Performs the Snap-On equivalent! I own a very busy mobile mechanics business, cordless tools are a life saver. I purchased this one after reading all the reviews and researching different brands. I have used cheaper ones (Ryobi and Craftsman) and have been very disappointed, I have used the Snap-On one, and was impressed but didn't like the battery life. I decided to purchase this one, it has not yet let me down! I haven't drained the battery in a single day yet! Takes off the rustiest, worst lugnuts such as old 4wd Rangers and beat-up AstroVans to name a few. Works on crank bolts and cam bolts without stuttering. If you are thinking about buying it, do it! Worth every penny, and it paid for itself within the first week. January 24, 2013
Rated 5.0 out of 5.0 by It is a beast I really wanted a solid cordless impact. I am a weekend shade tree mechanic without a compressor. I wanted to be able to take tires off and do some heavy duty things. I was not disappointed. Came with 2 batteries, charger and unit. Charges fast and removed almost everything I threw at it. Even ran a ball joint puller most of the way. Would definitely recommend! September 2, 2014
Rated 5.0 out of 5.0 by Awesome I would never put this thing down if it wasn't so heavy. And if I didn't have a wife I think I'd be sleeping next to it August 5, 2014
