Customer Questions & Answers

Will this be able to run using Husky's 8 gallon 125psi 1.5hp air compressor to do occasional automotive work

Asked by: James
I have that exact setup. 8 gallon Husky air compressor and this 800 ft lb Husky impact wrench. Using the recommended 25 foot 3/8 hose this impact works beautifully for occasional automotive work, and I'm not just talking about lug nuts. In the couple days that I've had it I've used it to replace my brake pads and rotors, both front axles, and rear shock absorbers. While the air compressor did have to run to fill back completely up after a couple rusted bolts, I was never waiting on it to continue my work. For the occasional automotive DIY, this combination works just fine.

Can you adjust the torque?

Is there more than one setting and if so, how much flexibility is there to adjust torque (just three settings, etc)?
Asked by: Giovanni22
Yes there is a dial in the back with 3 setting and it has a variable speed trigger.

IR not working with 26gal air compressor

I got this impact wrench a while ago as a gift. I'm now trying to use it and it has no torque. It won't even take wheel lug nuts off the car ...a task that that I can easy use a lug wrench for. I can basically grab the socket in my hand and press the trigger without fear of breaking my wrist. What am I doing wrong? I'm using 3/8" 25ft rubber air hose. The air compressor is a cheapo Harbor Freight brand but is fairly new and I've used it with other types of air tools with no problems. I even tried using my 5gal Craftman compressor...and got the same result. I have it currently set to 90psi and I have the IR on the highest setting (I've tried them all actually) I even went up to 100psi and still nothing. I'm hoping it's user error and not a defective unit as I don't have a receipt for it and its been a sitting in my garage for more than 6 months.
Asked by: NK
I am running a 60 gallon compressor with a 11.5 scfm I was using an old craftsman gun rated at 400 foot pound of torque and it wouldn't even budge my lug nuts. At first I thought it was a dud. One day I was re configuring my fitting setup and as I went to put my cheap $5 HF 1/4" regulator (which by the way is the same one HD sells for $20) as I was putting it on it exploded into over a dozen pieces. Needing to use the impact right away I did without the regulator and without it the craftsman gun zipped the lug nuts right off. So what I'm saying here is make sure you have a quality regulator or it can totally bottleneck your air flow. It's a good possibility that your regulator is not up to the task and is causing problems. even though my CM gun was working fine now, a friend had actually given me the CM gun to use and at half the power and twice the weight CM was still charging $90 for it which I though was a joke! So I decided to pick this one up because your can't beat 800 FT. -LBS for $110 and also because it is a composite housing it weighs less than half my CM gun which is great! I will just be giving the CM back to my friend because I never really liked it and It's ungodly heavy! Anyways definitely check that there's not a problem with your regulator restricting airflow

1/2" hose fittings?

This is listed to have only a 1/4" air inlet, which sounds like a bottleneck for a gun like this. Would I be able to use 1/2" fittings in this gun? Thanks.
Asked by: Zack
Don't waste your time or money using larger fittings. The tool can only provide the designed torque. Meaning, the interior valves are sized to the working limits of the air tool so you could install 2" fittings if you wanted but the air still has to pass through the interior lines which are much smaller so the extra air is useless. Read the cautions and it will specify the rated maximum input pressure. Any more will only ruin the tool. Would a larger gas tank on your truck give it more power? Probably not; but you could go further between stops.

1/2 in. 800 ft. lbs. Impact Wrench is rated 4.1 out of 5 by 99.
Rated 5 out of 5 by from Not for shadetrees This is a top impact gun tried on my service truck compressor nah that isnt gonna work. Hooked up to my works aircompressor that joker will bust the nut loose on 50 ton crane tires !! Well worth 100 dollars. Make sure you oil it everyday

Rated 4 out of 5 by from Initial quality/value very high - case needs a boot This gun is lighter than my old-school all-metal gun. The controls are very convenient. Like many I don't have the $$$ to throw at industrial products. I was looking at HarborFreight Earthquake guns which are similar price ballpark, but this has some of nice advantages: 1) low-med-high force dial applies in both directions (loosen & tighten) where as HF only have "high" for loosen; 2) the forward/reverse knob is much more convenient than turning the force dial on HF and others. 3) HD/Husky offer 2 year warranty out-of-the-box, while HF only offers 90 days. The torque on this is much higher than my old gun - its' plenty for what I've needed so far - no idea how it stands in absolute comparison to others. The composite case will scratch quickly on driveway/ground - in a few uses mine show substantial superficial scratches (nothing so far to concern me about integrity of the wrench) - this could really use a protective boot like other professional wrenches - nothing available from HD/Husky that I can find. Am trying to retro-fit another brand's boot onto it. I believe this is a great value (5 stars worth) but subtracting 1 because I really want a boot, which I am willing to pay for.

This worked great fresh out of the box, as soon as I got the fitting on the end of it of course. I have 3 vehicles and one of them has wheel lug nuts that are torqued to 100 ft. pounds. This wrench, on the highest setting, pulled them off with ease. Unsure what the actual torque is at the lowest setting, but that is what I used to put them back on, and just torqued them tight by hand to get the exact spec.. Nice product unlike the other cheaper Husky wrench I bought a few weeks ago. I can't wait to write the review for that.

Rated 5 out of 5 by from Great product and would recommend Bought this cause my old craftsman was either not strong enough at 300ftp or just tired. It just could not budge a harmonic balancer bolt. Got this cause I believe that it is a good value. Put this baby on the bolt tapped the trigger and the first hit turned the bolt. I believe that this product will be a great help on down the road.

Rated 5 out of 5 by from Monster of a gun, punishes any bolt with ease! This gun is amazing! First off it is simply a monster 800ft lbs easy! I love the composite house it makes it light weight, the forward backward switch is nice and the power setting control knob is high quality, the ring holder that holds sockets on is great it's not to tight or to loose. Prior to this gun I had an IR titanium running 780ft lbs, with a claimed 1200ft lbs of nut busting torque, unfortunately my IR was stolen and I had worked in the truck industry for 15 years now not doing that for a living anymore I couldn't justify spending over $300 on a new IR so I got this Husky 1/2" 800ft lbs Impact Gun, well so far it has done everything my IR ever did and at a third the price, I'm am very impressed with this gun and I highly recommend it! Before I purchased this gun my friend had loaned me a craftsman gun and it would not remove lug nuts and I know I'm running enough power with a 60 gallon compressor running 155psi with 11.5scfm at 90psi, so I went and bought this gun I had my eye on it for months. before I used it I was re configuring my air filter, ball valve shut off and regulator setup, as I went to tighten my regulator it exploded into about a dozen pieces and reading up I realized it was way to small for my setup. wanting to try my new Husky gun I just ran without a regulator to give it a shot. first I flooded it with oil like the manual says to do and then ran it in both directions for about 30 seconds. Then down to business I put it on my truck lug nut that i had tightened with a 24" breaker bar and all my weight on it, I put the gun in reverse and bam it took that lug nut off faster than I could blink an eye! I proceeded to take of the other 5 lug nuts and zip zip zip I felt like I was in a NASCAR pit crew! I ran all 6 of those bolts off in less than 20 seconds! and the compressor used hardly any air and never kicked on it only use about 5 pound of air. I should mention that I was running 50 feet of 3/8" air hose and I was using those new husky high flow aluminum fittings Model # 036-0138H, and believe me those suckers push some CFM and psi! Let me put this straight right now, ANYONE WHO SAYS THIS GUN HAS NO POWER IS NOT RUNNING ENOUGH PSI OR CFM TO IT! You had better get yourself in line and not try to run some little 8 gallon compressor and then try and say that this gun has no power and is junk, the fact is that if you can't run this gun then your compressor is junk or your air is getting bottlenecked somewhere. So if you can't run this gun then take it back and realize your compressor isn't made to run serious air tools or buck up and buy a real compressor if your want to run a real 1/2" gun and you want to run other serious air tools and if you do that then you'll see the real capabilities of this gun and realize that it's a beast!!!

Rated 1 out of 5 by from There is NO way this wrench delivers 800ft-lbs with a compressor producing less than 5 scfm at 9... There is NO way this wrench delivers 800ft-lbs with a compressor producing less than 5 scfm at 90psi, as claimed on the box and in the specs. Not even close. The wrench was not able to turn some bolts on my car even after I had loosened them with a breaker bar and cheater pipe extension. I estimate that I put about 400ft-lbs on the bolts to loosen them. The wrench was not able to match that. This is one of the few tools that I felt compelled to return after I had used it, because it simply does not work as advertised.
