This sucker cracks rusty truck lug nuts with ease. No breaker bar needed to get that initial crack . Great for out in the middle of a farm field or on the highway where no air compressor is available. I dont even use my air impact guns anymore..even in the shop.

Frankly this thing is a tank. I got it because I had to replace the stump jumper and blades on my bushhog. Long story short I hit a chunk of buried metal and shredded the blades. My phunumatic impact could not get the bent and messed up bolts off. This thing didn't even struggle. The head size of the bolts is 1-1/2 inch. It took them off like they were 5mm. A bit heavy but you'll get used to it. It rotates quick. And functions great. I assume it's gonna drink the battery cause of the power.

This has over exceeded what I was hoping for. It has never failed me yet has worked on every job I have used it at and great battery power. It is not to big but has huge power. Is dwalt so you know great quality. It is so fast and powerful watch how hard you push the button.

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.

The breakaway torque of this thing is amazing. I usually keep it on bolt mode so it eases into it. It's broken rusty exhaust free without breaking studs, and it has taken off most of the axle nuts we've thrown at it with the first try, with minimal effort, and very smoothly.This definitely keeps up with the other snap-on and Milwaukee air and battery impacts we have around the shop at a very reasonable price point. We'll see if the quality holds.

***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.👍

I have a 3 foot breaker bar that I used to change the wheels on my Bentley GTC. That thing is torqued at about 110 ft lbs. Still takes a bit of effort to do it by hand, and you need to have the car sitting on the ground, not in the air with the wheel loose when you're trying to take it off manually. If you don't, the wheel will just turn. I'm not weak by any means, but using the breaker bar as opposed to this thing is a night and day difference.I bought this DeWalt, and I'm able to pull the wheels off in seconds, with the wheel in the air, and it doesn't budge. This thing has so much torque, it feels like you could pull a house off its foundation with it. They aren't cheap, but they are incredibly effective.I set it for 100 ft lbs to put the wheel back on, and then I just go over it with a torque wrench to bring it up to 110. It's a matter of seconds.The only thing you need to ensure is that you've got the lug nuts screwed in a few threads before you start on this, otherwise you'll destroy it if you cross-thread it. And you could probably cross thread it all the way down to 500 ft lbs of torque...I love this tool! Make sure you get at least a five amp battery pack for it.
