ACDelco ANI405A Heavy Duty Twin Hammer ½” 500 ft-lbs. 5-Speed Pneumatic Impact Wrench Tool Kit

I had a stubborn (and rusted) blade bolt on my riding lawn mower that I tried everything to get loose... nothing worked. My last attempt before bringing the mower to a repair shop was to try this impact gun. First try once my compressor reached 100psi and the bolt came out in seconds. Solid tool that worked masterfully. Highly recommend if one has a tough bolt to extract!

Good price and works on all the cars and teucks i used it on so far

will do a follow-up edit in 6 months to update this review.update: next time i had to use this for lug nuts, it was unable to remove them. also noticed the instruction manual says nothing about the 0-5 settings and the dial spins outside of that range so u're left wondering how the tool handles that. if i could still return this item, i would.

Just used it for the first time! I have used impact guns in the past. This one works well. Will see how long that continues. Bought a vehicle and the lugs were on TIGHT. This got them off easy. Will need to get some impact sockets before long. Fathers day is coming up!

I have a 6 gallon compressor. It works fine for what I need it for...rotating tires at home.

It gets the job done

Let me say first off, as you compare pneumatic impact wrenches, consider your air compressor and line! There are other tools out there that will deliver more power and higher speeds than this one, but they require at least twice as much air flow. A big compressor and a 3/8" line work fine. My 6 gallon pancake compressor and 1/4" air line won't power those. They powered this AC Delco tool just fine. I had some tough lug nuts to get off, it took a few moments on each but I could see the nuts turning ever so slightly with each impact and all 5 did eventually spin free with no damage to the studs.The circular wire clip that keeps the socket seated on the driver was a tough booger and getting the socket on required tapping socket and wrench against the pavement. I feared I'd have to pry it off with a crow bar when done, but I pulled it free by hand. Maybe it won't be so argumentative next time.I like that the body of this tool is metal, not plastic. It's probably "pot metal" and will break if I drop it, but I like the feel of it better than plastic. It's an "old school thing".Since I just got it I can not address durability yet.

This impact air gun deliver some heavy torque on bolts that need to torque more than 400Nm/500NmGreat investment
