***Warning: Review by a DIYer home mechanic, not a "day to day" professional mechanic.*** ********************************************************************************************************************* The Good: Very powerful. Forward. Reverse. Don't matter. With a DEWALT 8AH battery pack on power setting #2, this thing unscrews 22mm wheel nuts and 21mm caliper bracket bolts very easily, even the ones with orange Loctite. Power setting #3 it's overkill most of the times to tighten anything and unscrews anything violently. Don't get distracted or this thing it's going to smack you and your wrist HARD. 😂 The built-in LED lamp emits enough light to see everything in front of the wrench in the dark. The variable speed trigger it's a must have on ANY impact wrench and here it works flawlessly. The pistol grip feels good on a bare, oily, dirty hand but much better and safer (stronger grip) with leather or rubber gloves on, as you should be equipped to begin with before start using this tool. ********************************************************************************************************************** The Bad: It's heavy. DEWALT claims 7lbs w/o battery. If you're planning on using it for extended periods of time and if you slap a big 8AH battery pack like a did, it's just going to get worse. Not a problem for me as I went in knowing that. Under prolonged heavy use you WILL physically destroy your batteries. The high power and the resulting vibrations are a double edged sword. I try to minimize the problem by grabbing the battery with one of my hands when using the wrench. DEWALT does not make the battery bumper, a.k.a BATTERYGUARD(TM) standard equipment, however, they'll be happy to sell it to you as an extra. That tells you that they know there's a problem but feel it's not critical enough yet to hurt their sales and tarnish their name. Time will tell. Don't trust the PRECISION WRENCH(TM) mode, use your own hand feel judgement and experience and you'll be better off. I tried it, then went over it with a manual wrench to assert my suspicions and felt it was way off when it came to applying the correct amounts of torque on different fastener types and sizes. The "run off prevention on reverse" feature did work as advertised but I see it more as gimmick than a true helping feature. JMHO. ******************************************************************************************************************* Final Thoughts: If you need a powerful and reliable cordless impact wrench, be it at home and even at the shop, you won't be disappointed with this one.👍

This is an excellent impact wrench and easily one of my most-used tools. This is the XR version, not just a standard 20V MAX, and you can definitely feel the difference in power, torque, and overall performance. It has no problem breaking loose stubborn bolts and handles heavier-duty work without hesitation. The tool feels solid and well balanced, even with extended use, and the build quality is exactly what you expect from DeWalt. Battery life has been great, especially when paired with XR batteries, and the tool delivers consistent power without bogging down. If you’re deciding between a regular 20V MAX and the XR line, this one is absolutely worth it. Reliable, powerful, and built to last — highly recommended for both DIY and professional use.

Bought a different name brand thinking I could take the lugs off my truck but it wouldn’t budge them. I went with this one because the foot pounds of torque were super high. I am not disappointed! It zips the lugs off like they’re nothing. Dewalt for the win!

I've been working on cars for a few decades now and own many Air Tools. Generally Air Tools are lighter and smaller than their battery powered counterparts which make them easier to handle and helps with getting in tight spots. But the air hose can be hindrance at times. Comparing the specs on my 1/2" IR Air Impact Gun against the Dewalt DCF900 Cordless Impact Wrench the latter seems to have the upper hand. 2135QTi Impacts per min: 1,250 Torque range: Forward ft•lb (N•m) 50-550 [600 Max.] (68-746 [813 Max.]) Reverse ft•lb (N•m) 650 [700 Max.] (881 [949 Max.]) Dewalt DCF900 Cordless Impact Wrench: Impact at a rate of 2200 IPM Max. fastening torque: Low mode: 100 ft-lbs, 135 Nm Medium mode: 600 ft-lbs, 813 Nm High mode: 1030 ft-lbs, 1396 Nm Max. breakaway torque 1400 ft-lbs, 1898 Nm Watching a video on YouTube for the Dewalt DCF900 Cordless Impact Wrench the ratings may be slightly inflated but were nevertheless impressive. So far I've only used the tool for loosening wheel lug bolts torqued to 90 ft/lbs on my car for tire changes and the Dewalt DCF900 Cordless Impact Wrench handled that easily enough on setting of 1 when paired with a DCB206 20v MAX 6ah Battery. The Dewalt DCF900 Cordless Impact Wrench is bigger and heavier which may come into play when I try to do some work on suspension and steering bolts where are notoriously difficult to remove and access can be tight. While it is sorta cumbersome, the Dewalt DCF900 Cordless Impact Wrench had no issues standing up on it's own when being set down. Also it operated very smoothly and I barely noticed the impacting when in use. I purchased the Dewalt DCF900 Cordless Impact Wrench for when Winter comes and the cold weather makes my Air Compressor difficult to start. Instead of heating up the Garage to get the compressor warm enough to start, I can get right to work. Saving time. I also won't have to deal w/stiff rubber air hoses when moving around the car. I'm sure I'll find uses for the Dewalt DCF900 Cordless Impact Wrench during the warmer months when I encounter something my 1/2" Air Impact Gun won't budge. Since I already had both a Dewalt DCB206 20v MAX 6ah Battery and DCB204 20v MAX 4ah Battery I didn't need the whole kit, so this item fit the bill in getting the cost down. I've own many Dewalt tools in the past and am sure this one will be a welcomed addition to my Tool box. I knocked off a star cause it is a bit heavy and the only complaint I have is the location of the button to change directions. When wearing heavy work gloves and picking up and/or operating the Tool it's too easy to hit that button and change the direction from forward to reverse or vice versa. I've never enountered that before w/other Battery powered tools from Dewalt.
