Rated 3.9 out of 5 by 19 reviewers.
Rated 5.0 out of 5.0 by Great impact gun for the price I bought this a while back for my job. It gets used everyday for about 6 hours a day. I oil it everyday like your supposed to. This gun works like charm it has no problems breaking bolts loose and the trigger is easy to modulate. The rear of the gun has the regulator. It has three forward settings and one reverse setting. All settings work as they should. The trigger and adjustment knob still feel just like the day I first tried it and over all the gun it self has stood up to everyday use. Just make sure that your air compressor is rated for impact tools because if its not than the tool will not have allot of power. April 9, 2011
Rated 5.0 out of 5.0 by Husky 3/8 In. Impact Wrench Light weight, plenty of torque for its size easy clear controls. I use this tool to undo bolts on my motorcycle, it works great for this job. I had to change a tire and it broke the lug nuts loose without a problem even though it is not made for this type of work. Definitely worth the money. November 7, 2009
Rated 5.0 out of 5.0 by Works well Once upon a time, many years ago, I did automotive repair for a living. I have a complete set of name brand pneumatic tools such as impact wrench, drills, ratchet and chisel. They're all very old but still function...kind of. Every morning I check Home Depot's site for their "Special Buy of the Day" and these Husky air tools were on special so I bought one of everything. I'm not disappointed, they work great. I didn't realize what sad shape my old tools were in until I began using these Husky's. They're far more powerful, use much less air than my old ones and have a two year warranty. I am very satisfied with this purchase. July 28, 2014
Rated 4.0 out of 5.0 by Great little gun. As a heavy mobile mechanic, air guns are very handy. I didn't want to spend an arm and a leg on a 3/8 drive impact. Found this one and let me tell you, very impressed. It can handle a good amount of torque and performs very well. Lube it daily before each use and for the money, you won't go wrong. January 6, 2015
Rated 5.0 out of 5.0 Worth The Price For anyone that says it won't put out more than 60-65 ft./lbs. of torque, it clearly says 65 ft./lbs. Just like any other tool, if you take care of it like it says, it will last. Have had it for some time, and everyday that I use it, I put the oil in it. Not a lick of problems yet. Worth the $25 it cost to buy online and ship it to the store. April 23, 2013
Rated 3.0 out of 5.0 by Decent Bought this impact because another guy had it at my shop and it works decently. This gun is advertised to put out 100FT pounds of torque, in no way does it even come close to that. This gun puts out like max 45-50 pounds. If your looking for power do not even think of buying this. If you want a 3/8s impact for low torque stuff then this will serve you well. The first impact that I purchased was defective right out of the box. Took it to work, oiled it up and as soon as I hooked it up to shop air it ran by itself and had no torque what so ever. The free replacement is working fine. January 2, 2012
Rated 5.0 out of 5.0 by Cannot beat the quality for the price I was extremely happy to be able to get the product I ordered. I had been looking for some time and felt that other stores were charging too much. February 11, 2014
Rated 5.0 out of 5.0 by Great tool for the price For the size and price this is a great buy for anyone looking for a light weight impact gun. February 11, 2014
