Rated 5.0 out of 5.0 by Now this is power I purchased this wrench to do tire rotations on my truck. It work great. After a few purchases and exchanges I learned that the problem was in the CFM of the impact wrench. As a DIY guy I have no need for a 40 gallon air compressor, and most impact wrench have a CFM rating of 7 or 8 which require a big air compressor. I have an 8 gallon 2 horsepower air compressor and it only kicks out 5 cfm's. This wrench requires that amount at 90 psi. It is also a twin hammer so it is smooth and alot quieter that the single hammer. If your looking for a powerful wrench, this will be the best $55 you will ever spent. February 7, 2010
Rated 5.0 out of 5.0 by 350 ft lbs for under $30! I paid closer to $50 for mine. I use it to change to snow tires in the fall and regular tires in the spring on 2 cars. I use it to fix get my mower blade on and off for sharpening. I have used it for about 5-6 years now. I add a drop or two of oil every time I use it. I cleaned it and relubed for the first time ever in 2011. It spent about 2 days in sewage after Hurricane Irene. I also disinfected it! I cleaned it for a 2nd time this spring. A pin fell out near the bottom of the handle. It was a 3x28, about $1. The only thing that ever went wrong. Works well with an 10 gallon, 2.5 hp HF compressor that puts out 5.3 CFM. May 30, 2013
Rated 5.0 out of 5.0 by Great impact gun for the price I bought this 1/2 inch impact gun a while back and I also bought the husky 3/8 inch impact gun at the same time. Both impact guns are used every day at my job. This 1/2 inch impact gun is rated for 350 foot pounds which I believe it is (when used with the proper air compressor). It has enough power to break lug nuts loose. But it gets used mostly for breaking lawnmower blades loose. I oil the gun daily like your supposed to and it seems to be holding up just fine. The gun has an adjustment knob in the back of it just like the 3/8 impact gun has. it has 3 forward speeds and one reverse speed. The trigger is easy to modulate. So fare both the this 1/2inch and the 3/8 impact guns are holding up just fine. For the price I payed I could not be happier. April 9, 2011
Rated 1.0 out of 5.0 by Garbage ,would give 0 stars if possible Save up for a decent brand, i should have known better. Not only came with the reverse side of the adjuster broken but very weak wrench. For those wondering, i have a 27 gallon craftsman pro that flows 7 cfm at 90 psi and 5 at 40 September 3, 2014
Rated 4.0 out of 5.0 by Inexpensive but needs a pro compressor I repair wheels for a living and usually use an electric impact. My generator died and I have been waiting for the replacement so I bought this impact to get me by (taking wheels off by hand is not fun). After reading the manual, yes I did actually read the manual, I was concerned about too much PSI to the tool. I dialed back my paint regulator to 100 psi and could not break a lug off of a wheel. I switched to my direct air line for my air tools (150 PSI) and this tool worked liked a champ. I felt like I was part of a NASCAR pit crew. Remounting the wheels I used the lowest setting and it torqued the lugs perfectly. With enough air and enough PSI this tool works fine. I think that the cost of the tool makes some novice users think it will work with their inadequate compressors. August 31, 2012
