Rated 3.0 out of 5 by 24 reviewers.
Rated 4.0 out of 5.0 by Not bad for the low price Let's face it, this tool sells for about 1/10 the price of a profession grade tool of the same size and capacity. So it would be unreasonable to assume it comes close in quality or reliability. Still, I think it is a reasonable light duty infrequent-use tool. Don't expect to use it for an everyday business. I noticed no abnormal operation during the fairly brief two weeks of time I have used it so far, although to be honest, nothing over a torque setting of 2 (or maybe 100 lb-ft?). It worked well with a small 6-gallon compressor, rated at 4 cfm. The tool weight is about what you would expect for this size, actually a little on the light side at 4.77 lbs. Attaching and removing the sockets was a bit difficult, as expected, since I did not want to oil the anvil as some folks do. I don't want one to come off while under torque. The manual says to pull off the bit with your hands ...or use a suitable tool. I used an ordinary screwdriver to pry them off. The direction control was also somewhat difficult to operate at first. I can't stress the importance of oiling the tool frequently. As a matter of fact, I think that should have been the very first step in the manual, since the tool will have been unused in storage for an unknown length of time. The inline oiler, which you should always use, would not be adequate to prepare the tool for first normal use. I would have liked to have seen a chart of torque/setting/psi values, but I suppose that would be asking too much. I do like the labeling of the direction switch (F--R) in "English" instead of universal symbols. Also, don't lose the black bag that comes with the tool. Use it always to keep the oil from drying too quickly. February 5, 2014
Rated 1.0 out of 5.0 by No good Worked well for 5 mins then after that it either blew air or (if I played with the fwd/rev switch) had near 0 torque. I added Husky air tool oil to the inlet before using and never exceeded max air pressure rating. Home Depot, you need to replace this lemon. April 5, 2015
Rated 5.0 out of 5.0 by Good Value The saying you get what you pay for is true. I bought this as a combination set with the air impact wrench and the gun for $18.00. If either one of them breaks I wouldn't be upset, due to me only spending $18.00 for both the air ratchet and gun both on sale. What can you expect for $18.00. As stated above, this is not a Snap On Impact Gun, but for what your paying for this is a gun for general use around the house. As for some of these reviews, I find them foolish, not to mention entertaining. One guy says, "It wouldn't even take the lug nuts off my car." My question, are you sure you know how to use an impact wrench or did you just see some guys at the tire shop and decide you wanted to wake up and be a pro? I pulled all four wheels off of a 3500 Cummins Diesel with this same exact gun today. So either someone either A.) Doesn't know how to use an impact gun or B.) Doesn't know how to utilize an Air Compressor, Check for leaks, etc. January 9, 2015
Rated 1.0 out of 5.0 by Junk tool would not recommend this to anyone. This tool would not remove lug nuts on my Frontier PU. I oiled tool with Husky air tool prior to using and my compressor is a lot bigger than needed for this tool. Total waste of time. I returned this tool and will not buy another Husky. March 16, 2015
Rated 1.0 out of 5.0 by Hmmmm Very weak tool. Tried to remove old bolts from vehicle, it wouldnt even touch them. Did it by hand. Tried it to install brand new bolts. Same problem, again did it by hand. Returning it immediately. March 8, 2015
Rated 1.0 out of 5.0 by You get what you pay for First use! Used it to rotate tires. Felt light and good. Removed lug nuts and retightened fine for the first 3 wheels. Then installing the 4th wheel, it stopped working. Shaft turned freely. Of course since it was a Christmas gift it is beyond the Home depot 90 day warranty. If I want to ship it to Chino, CA for repair for $17, I'm sure they will fix it under the 2 year warranty by Husky. Made in China. $29.98. March 7, 2014
Rated 2.0 out of 5.0 by Didnt work for me I have a 12 gal air compressor I oiled it good but just wouldn't work, I could hold the socket and it wouldn't move but Home Depot returned it with no problem. I will always shop here. February 21, 2015
Rated 1.0 out of 5.0 by Not worth it Bought this to rotate tires on our cars. Used it with 8 gallon Husky air compressor set up to deliver proper psi. After about ten minutes of trying I still did not have a single lug loose. I ended putting this piece of junk back in its box and did the tire rotation with a breaker bar instead. I will be retuning it. October 4, 2014
