DEWALT20V MAX Cordless Impact Wrench, 1/2 in., Bare Tool Only (DCF900B)

***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 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.

I love this thing it's heavy and powerful. Don't forget to get a raincoat for it they sell several different ones that slip on it'll really make a difference while it's laying on your garage floor not scraping it up. This thing really is a beast

It’s heavier than my old one but it works so much better.

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

Way more power than I'm likely to ever need. I'm a little unsure if I like the gradual (I can't remember what they call it) go faster feature, but it does absolutely everything I could ever want. It is so powerful I might reconsider my personal needs and opt for a smaller body that can fit into tighter places. No matter. This baby is a beast.

Finally ordered one and I have been so far very impressed. It has plenty of power to get stubborn bolts broken free. The price is good for what you get, this is the bare tool only but I had batteries already.Only downsides would be the weight and size of the tool. It is a big tool, but for the power it provides it needs to be big.Have only had it in use a couple of days and it's not used all the time so I cant comment on battery life.
