Rated 5.0 out of 5.0 by Beat a Snap-On today I was removing a large vehicle body from its chassis today. I pulled most of the bolts with a 48" breaker bar (& considerable effort on my part) but i couldn't get an angle on the last 3. My old impact gun just wasn't up to the challenge, so I borrowed a Snappy from a buddy of mine. It's one of the standard duty ones, so it's probaby around $400ish. It couldn't do it either. Husky & their blue competitor's tools have been really impressing me lately, so I picked this one up to see just how good it really is. It had to really work at the 3 bolts, but it eventually pulled them. I absolutely believe the 800 lbft rating on this tool. I highly recommend it. August 23, 2014
Rated 4.0 out of 5.0 by Priced right. Purchased today, Tuesday Dec 22 2014, will not go to work until tomorrow. The feel of the tool is good and the Forward /Reverse is the type I prefer, plunger style for quick direction change. The only concern here is the plunger appears to have plastic caps screwed onto it for a positive stop in the housing. Time will tell if they are to be a weak point or not. I work on RV's so this will get plenty of use removing wheels, installing hitches and couplers. I will write an update once I have used it a while. This is the first composite bodied air tool I have owned and also my first Husky impact. The price is good, not sure who makes this new line for Husky? December 23, 2014
Rated 5.0 out of 5.0 by Great Impact Wrench if you have the right compressor This is a solid wrench that CAN do just about anything however the key to get the performance out of this wrench is having the proper compressor and lines to support it. Without the right compressor and hose you may get minimal performance out of it. To start you need a 3/8" line that is no more than 25 feet long as per the manual. The little coiled up lines you get with smaller compressors are usually on 1/4" and are worthless for this tool. Second, most compressors under $250 don't have the a high enough SCFM rating to run this tool at 90PSI. Example - A pancake compressor may put out between 0.7-2 SCFM. A small compressor on wheels might put out 2.7SCFM. A rare few with smaller than 10 gallon tanks will put out 4CFM. Husky makes one for $129 that puts out 4CFM with an 8 gallon tank. This likely won't do it for you. This wrench requires a compressor that can handle 4.4SCFM on AVERAGE. That means that if you have a particularly stubborn bolt/nut it'll be using upwards of 18 CFM under load. Now, you can compensate for what it needs under load with a larger tank such as a 30 Gallon that has at least 4.4SCFM. The people that have given this high ratings are people that likely have the right compressor. The people that have given it low ratings likely don't have a compressor that provides the right output for this tool. Hope this helps. November 18, 2013
Rated 5.0 out of 5.0 by This product "Air Impact Wrench" is a essential to me, currently restoring a classic corvette. The torque selection is a plus for this tool and the ease of using the impact wrench in tight places is a big help. April 22, 2014
Rated 5.0 out of 5.0 by Awesome gun if you use it properly! While working on my dads van, we realized the cv nuts were seized. My 400lb impact wouldn't budge them, and my breaker bar was bending like a crescent moon and still not budging. I grabbed an old ratchet I have that usually works after I have broken my 1/2in drive breaker bar, well, I had a 4ft piece of square tubing on it for leverage and it snapped the 1/2in drive of the ratchet. Teeth are still fine. Go figure! Out of need I went ahead and grabbed this impact as I have had my eye on it awhile anyway. I filled it completely full of oil, and ran it in both direction for about 45 seconds to make sure it was good and lubricated. I had it hooked to about 125ft of 3/8ths hose, and my compressor is rated to 21.5cfm@105psi. It took about 15-20 seconds of impacting but the nut broke free and spun right off. Worked about the same on the other side as well. Those cv's are the originals from 94. Even using a hose 5 times the length recommended it did the job without issue. The only thing I do not like is that it is composite, which makes it lighter, but I would prefer a metal housing for durability. Excellent gun for the money! I definitely recommend it, however make sure you oil it properly and follow the break in etc.. and have a compressor and lines that can keep up! September 15, 2014
