The impact itself works great but during the first use one of the bolts on the back flung out we put it back in and tightened it but the same one keeps flying out and leaks oil out of the hole.

5.0 out of 5 stars Very nice impact
Reviewed in the United States on July 11, 2022
Verified Purchase
This impact works great. It’s lightweight and has a quality build, very comfortable and not too big, it’s just right. I bought it for lug nuts. I use it with a Dewalt 6 gallon pancake compressor that is for my air nailer and it works, in case you were wondering if it would. It’s probably not ideal but it works great for small jobs. I used the air fitting that came with it, put a few drops of oil in the fitting and I was up and running. I use it on its lowest setting and it zips the lug nuts off in about 1 second, no hesitations at all. A bigger compressor would be better but for doing all 4 tires on a truck or car this thing works great with my little Dewalt. It’s good to go, great product.

I'm very surprised how fast it came. It came in a few days then it supposed to and I'm very happy for that. Also it is strong, clean and smooth. Not to crazy and not to weak. Right in the middle power just well needed for all around situations. I abused the hell out of this tool 10 hrs a day and it still going strong. Right out the box I dripped some oil it in it and I smiled when I pulled the trigger. It's not that loud and it's easy to the ears. It's also powerful and gets the job done. I heard some weaklings saying it's a little heavy. Hell no it ain't that heavy. You can maneuver this thing easily. The other senior technians were surprised about it too. The best thing is you don't have to pay some much money. You can equally get the job done compare to snap on or Mac tools crap. I feel bad for those debt slaves spending over 500 for those air tools. Dewalt never failed me. I dropped it a few time and still run strong. Highly recommend it buying this now!!!!!!

Use it daily in auto industry. I find the matco 1/2 air tool too jerky and unpredictable. This tool is much more affordable and though it may not have thr break away that the top dollar air powered tools have its a fantastic choice for anyone who is getting into automotive or needs am 1/2in impact for their home.

My one complaint is the grip has moved on me from years of use but it is not a big issue.

I want to add Dewalt did a great job with the internals of this impact. It's extremely smooth breaking and fastening.

Had some heat-seized lug nuts and unfortunately this was unable to loosen them. However neither was the air impact at a local shop. It took a 4ft long breaker bar to bust them loose. At least it will be useful for future uses.

We tried everything and about 4 different tools including a breaker bar and other electric wentches to get a nut off of an old riding lawnmower We were actually going to have to call someone in because we needed to change the belt. We got this as a last ditch effort to see if we could get it off and with the air compressor, it slowly unwound it and freed the nut. My husband was ecstatic! This is one tough tool that you need if you're having trouble.

5.0 out of 5 stars Best impact I've ever had
Reviewed in Canada on January 11, 2024

Even on the lowest setting it takes off lug nuts with little effort. Love that max torque of 650 ft/lbs with my 105 PSI 7.5 CFM compressor. My cheap impact maxed at 100 ft/lbs and wasn't good for much of anything. Cost less than the electric or cordless and twice the power. Dewalt even supplied a seal threaded line nipple. The D-ring doesn't hold the socket to hard, I just pull them off by hand. Might be the last of when America products actually stood for quality. Priced as if they want to discontinue the product so get yours today.

I was tired of purchasing expensive impact guns that immediately fail once the warranty has expired. Those expensive guns cost 600 to 800 dollars and are junk. (Mac Tools) This Dewalt impact has me very impressed for its performance and price range. I'm constantly using this with 1 inch and 1-1/8 inch sockets and it hasn't let me down yet. I'm very happy with this impact, now time will tell how long it lasts. So far it's been 4 months and still very happy. Only downside so far is that the gun is a little on the loud side but not a huge concern.
