    • This thing packs a PUNCH and HEFT.
Color: Black/Yellow Size: Large
***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.👍 ... show more

    • Great tool.
Color: Black/Yellow Size: Large
It’s heavier than my old one but it works so much better.

    • Powerful!!
Color: Black/Yellow Size: Large
Love this impact wrench! Lots of power for a battery-powered impact wrench and it was able to dislodge the bolt that some overzealous automotive tech at my dealer tightened it with! After I tried using 3 and 4 foot breaker bars to no avail!

    • Powerful , need to use a 5 amp battery
Color: Black/Yellow Size: Large
This took the lugs nuts off my grand Cherokee and bolts on my rusty boat trailer suspension no Problem super powerful. You for sure need a 5 amp hour battery though. You won’t get the full power of this impact with the use of 2 hour dewalt battery. I had original tried one of the generic impact wrenches but ended up returning. This one was pricier but worth it in my opinion. ... show more

    • This big dog eats.
Color: Black/Yellow Size: Large
This thing is a beast. It’s quite large and not something you’d necessarily want to have as a daily use tool, but keep it around for heavy duty work and it will make light work of a whole lot of stuff. Rusty 1” nut on a 60 year old truck? This thing took it off as if it was fastened with 5 FtLbs

    • Powerful tool
Color: Black/Yellow Size: Large
This thing is impressive! I’m an auto mechanic and this thing does stuff my Snap-On won’t do. The battery life is very good but remember to get full power you need to use a flex battery. The only kinda negative thing I would mention is that it is heavy, not unmanageable but heavier than an air gun.

    • Very good tool
Color: Black/Yellow Size: Large
This is a great tool. Very powerful. I used my old one until it just doesn't have the power it used to. I took apart the old one, the hammers still work well. That is the limit of my expertise. Dewalt has gotten rid of most of their sercice centers. I guess these are disposable tools now like everything else. While it lasts, it's a joy to use. ... show more
