Right sized tool for a resonable Dewalt price.
Style: Impact Wrench
Review Image by Adam Paul
I volunteer with a nonprofit organization that builds home ramps for people with limited mobility. We use a long 3/8" lag screws to mount 4X4 legs and 9/16" bolts to couple ramp sections. This has the power to easily handle both jobs. I use a 6-amp after-market battery that has completed every build I've taken it on. Some team members have larger power wrenches, some have more power, some are less expensive. But I feel this is a higher quality tool that gets the job done. ... show more

How did I manage before this thing?
Style: Impact Wrench
When I was younger, I used professional air tools & wrenches, and they worked well with enough space, but were bulky and required annoying hoses & compressors. I've been working on cars for 40 years now as a hobby and finally decided to try out a cordless impact wrench since I already had DeWalt cordless drills and grass edgers. The 20V 3/8 drive impact arrived quickly and I was shocked at how small the box containing it was, as well as how compact and light the tool was. I hooked up a small, 2.0mAh battery to it and it blew me away. Lug nuts on the car were removed with no problem, the rear differential and axles I worked on were taken off in less than 5 minutes. This was normally a 30-minute affair with conventional hand tools. The tool's compact frame and super light (but powerful) build actually made the work enjoyable, with plenty of room to fit in most spaces that my hand tools did before. I can't believe I waited this long to get this cordless tool...faster, easier, and fairly inexpensive considering how much quality tools cost. I highly recommend this impact wrench and don't know how I managed before I got it! ... show more

Very Good & Handy Impact.
Style: Impact Wrench
This tool has plenty of torque, not sure why people are saying it doesn't. Unless you're not using the 20V battery, don't expect to get anywhere near the 150 ft/lb because the 12V battery won't supply it. This tool works easily and makes for quick work on brake jobs. I wish I bought this first before getting the 1/2 impact because this tool is pretty light and easy to maneuver in tight spots as well. ... show more

My favorite new power tool
Style: Impact Wrench
I'm not sure why this gets such negative reviews (youtube, forums, and such). A lot of people say that there is a huge power loss in this one with the 3/8" anvil versus the 20V with the 1/4" chuck. Maybe that's true, but this has plenty of power for its size. And the advantage to this one versus the one with the 1/4" chuck, is this one with socket installed is shorter overall than the other. So I can get it into places the other won't go. I have been using the 12V Max impact with the 1/4" chuck for about 5 years. I absolutely love it, but it lacks power for most bolts over 10mm. I have used it everyday at work though removing valve cover bolts, intake bolts, skid plates, splash shields. Pretty much anything with a 10mm bolt or smaller, and some things with larger bolts. Plus its great for running in oil pan bolts, because it doesn't have gobs of power, I don't have to worry about cross threading bolts while blindly running them in. Now, as far as this 3/8 20V Max XR. It has quite a bit more power. The 150 ft/lb rating is only sorta accurate. I have attempted to remove torqued bolts to over 100 ft/lbs and this gun will not do it. Bolts torqued that high that have lock tite, or rust will likely be too tight for this impact. On the other hand, freshly torqued bolts with clean threads, this impact will remove well over 100 ft'lbs. That is assuming you're not using an 18" extension with a wobble socket. It removes lug nuts easily, if they were torqued correctly with a torque stick, or torque wrench. Im using the impact with a Dewalt 5 mAH battery and the charge lasts forever. I still use the 12V Max every day at work, but now I use this one every day as well. I use it for a lot of brake jobs, smaller suspension bolts, basically anything up to about 21mm, and it usually removes them easily. The battery will last with that type of use several weeks. I still have to use my air impacts when I need more power. For my 3/8 air I have the Ingersoll 2135 tiMAX. The ingersoll will beat this dewalt every time, but air hoses are annoying, so I reach for this first, and only use air if I have to. So yeah I'd recommend this to anyone tired of dragging around air hoses, or even for home use. Maybe it doesn't have tons of extra power to spare, but for its size, and convenience, it has plenty. I didn't buy it thinking it would be as strong as my Ingersoll. I bought it because I knew it would be close enough that I wouldn't have to lug the air hose around as much. ... show more

Handy as a shirt pocket.
Style: Impact Wrench
Handy as a shirt pocket. Light weight, no hose to drag around. Used it to completely disassemble a rusty '74 Jeep CJ5, what it didn't unbolt, it sheared off! Guess I should have used more Kroil penetrating oil. Plenty of torque to unbolt up to 1/2" bolts that were badly rusted. You may want to get a bigger battery, 4 or 5 Ah if you are going to use it a bunch. ... show more
