I own a business where we source vehicle parts for various shops - obsolete parts, discontinued parts, and when we're unable to locate NOS parts - used parts. I purchased this impact to replace another cordless impact that died, for mobile-use in areas where power is not available and extension cords are impractical (e.g. body shops, salvage yards, etc.).

While I've found this impact wrench to be more than capable, it has two major short-comings for those considering a battery operated impact for shop/professional use.

First, the anvil incorporates a detent pin, for retaining the socket. This makes the placing/changing a socket on the impact difficult, for most sockets. While those sockets with considerable wear usually go-on without much fight, most sockets either have to be forced onto the anvil, or the detent pin has to be manually depressed to get the socket to slip over the pin. Removing the socket can be even more problematic, if the detent pin is accidently placed into the retainer-hole that is drilled into most impact sockets. You must use a small diameter phillips or torx screwdriver to manually depress the detent pin, before it will release the socket.

Second, the "trigger" switch is non-standard and functionally poor in design. Unlike most impacts, the switch is a pivoting type of rocker-switch that is approximately 2" in length. This requires you to either reposition your hand to change from removing a bolt/nut to tightening a bolt/nut - or to use your index finger for removal and ring-finger to tighten. Several people "inadvertently" used the impact in the wrong direction before getting use to the rocker-switch, and in one case significant shop-time was wasted extracting a bolt that was sheared as a result.

Great price without the battery. Very powerful. Able to easily remove lug nuts without effort or the need for a breaker bar.

Get it if you need something small (relatively) that can remove multiple sets of wheels without breaking a sweat.

Only gripe...the trigger. It isn't like a regular dewalt drill where there is the button you push back and forth to change the direction the drill goes when you pull the trigger, the trigger has an upper and lower portion...a little harder to use but fine none the less.

Good tool and price but one problem, the socket retaining device broke the very first time I used it.
The impact socket wouldn't come off for anything the first time, I ended up putting the socket in a vice and pounding the socket off with a punch and hand sledge though the center of the socket. Retainer parts flew when it finally busted loose. Don't think there was anything I could have done differently. I'm sure I could send the unit back but it seems to hold the sockets on just fine without the retainer. Besides I don't see how a replacement wrench would be any different.

As far as strength goes, it was able to break a 8" long 3/8" lag bolt in half. I've been grabbing it every time since I got instead of my 1/2" IR pneumatic impact. It's been able to break loose tractor tire lug nuts that were torqued to 250 ft/lbs.
Hard to beat that.

Over a year later,,,
I hardly ever use the thing any more, way too heavy. For the majority of wrenching I need to do this is excellent Milwaukee 2456-20 1/4-in Cordless M12 Lithium-Ion Ratchet (Tool Only)

First of all, I never had air before. So I bought this instead of buying compressor and the hole nine yards.

I already had a 18v dewalt drill with a nicad battery. The battery is about 1 year old with not much use. At first when receiving this impact drill, I felt weak power so right away I made sure by fully charging the battery I had and trying it out. It worked well, but with automotive you know there are some stubborn bolt/nuts because of normal oxidation and things. So I would use heat/breaker bar then this which worked fine.

So just a month ago I bought the new dewalt lithium-ion battery with charger. Charged the battery and it sat for like 2 weeks. Finally had some work to do on a car where my elcheapo air tools frustrated me. Pulled out the impact drill and plugged in the new battery.

This beast blasted nuts off that I even had a hard time with a 18 inch breaker bar(more to do with position clearance; I have some guns on my arm).

So I came to the part where I put the new parts in. Normally I would torque to specs but I would at least use the drill to get close where i don't need to ratchet. I accidentally broke a bolt with this drill. It works so fast that I wasn't able to release and sure enough it snapped off the bolt with nut. Luckily it was an easy fix but I just wanted to warn people not to underestimate the ft pounds mentioned on this tool.

great job dewalt and great job amazon for price and delivery.

I am a full time mechanic by day, and then I get to work on all my friends busted cars at night in my garage. I am used to having power at work so I decided to go to sears and buy a compressor and air tools for the house. I got the 37 gal professional and a mid-range gun. I was so disappointed with the performance I took it all back to sears and got my $400+ back. I went back to using my breaker bar and muscles to break things loose until I happened to be wandering through lowes and saw this sitting on the shelf. I thought for less than $150 and a good return policy I'd give it a try. I already had a dewalt xrp 18V drill at the house with 2 Li-ion batteries and a charger so I took it home and put it to the test. I was amazed how well it performed. It is now my go to impact tool. It doesn't have the power of my Thunder Gun but it will do most jobs and there is no air hose to trip over. I WILL buy another when I wear this one out.
