Rated 4.7 out of 5 by 15 reviewers.
Rated 4.0 out of 5.0 by Great Product Buy this one and I'm satisfied with the performance highly recommend July 3, 2015
Rated 5.0 out of 5.0 by Powerfull Highly recommended. I purchased it at my local Home Depot along with a drill set that included two DCB207 batteries. To my surprise one of the batteries already had a full charge as indicated by the charger. I took it to my garage and in a little more than 2 minutes, using the van's jack and a 3/4 socket, I had the van on stands and the wheels off. It not only had enough power to take the lug nuts off, but it jacked the van up with ease. Both tasks took mere seconds. I'll be putting this wrench in our van for our holiday trip across the turnpike. The trigger is a much improved version than that of the 18v DW059B in that it slides straight back, and doesn't tilt like the 059 making it seem like it handles better. It is heavy like the 059, but that is to be expected. The detent seems hard and made it difficult at times to put a socket on. But compared to the other features, it is a minimal gripe. The built-in light wasn't helpful until I needed an expedient light source. I simply tapped the trigger and I had several seconds of light. And, of course, it uses the 20v max batteries which seem to be a much better system than the 18v. Bottom line, it’s a good product worth every penny I paid for it. The Home Depot I shopped was excellent as well. The attendant in the self-check-out line had the tool to take the security tag off so I didn't have to wait in a long line. This was my first Dewalt purchase, but It won't be my last. December 21, 2013
Rated 5.0 out of 5.0 by Awesome Impact Wrench This is an awesome impact wrench. Easily handles everything I throw at it, including lug nuts, lag bolts, etc. I've used it for rotating tires on all my chariots, repairing my deck, building some planter boxes in my backyard, and screwing anchor bolts into my garage floor. Be sure to get the 'new for 2014' Type 2 model which features 400 ft-lbs of torque vs. 300 in the older Type 1 model, and a few other improvements like variable torque control at the trigger, repositioned LED light at the base of the handle, and battery level indication using the LED light. You can tell the difference by the redesigned nose cone on the Type 2 (the one with the horizontal slats). April 14, 2014
Rated 3.0 out of 5.0 by good for home use Bought this to help with putting a suspension kit on a 2011 mustang. It took one battery for the front and one for the (2 batts. total). Worked great for that job but it is bigger than most 1/2 air impacts. April 14, 2015
Rated 5.0 out of 5.0 by Works Great Works great on all nuts. For those over torqued lugs from tire shops just make sure you have a fresh charge on the battery and it will break them loose. No hose to deal with makes it much more convenient to use. April 7, 2015
Rated 5.0 out of 5.0 by best product Was leary if it was as strong as air impacts, I was surprised! Not only strong but did with less effort ! It also seems better then corded units. April 8, 2015
Rated 5.0 out of 5.0 by Very good quality impact wrench Very strong impact wrench, have only used it a couple of times but very impressed!! The only thing I don't like is the detent pin that holds the socket have to have something to push it in to take off socket. March 25, 2015
Rated 4.0 out of 5.0 by a little slow tons of power I have a bunch of other 20v tools was very happy to pick this one up, has more power than my pneumatic impact although is a little sluggish losing bolts, and lugs but still more than enough power to do the job December 10, 2014
