Will turned us on to this wild tool from Harbor Freight that we’ve never seen in the store: a 1″ gasoline-powered impact wrench. He writes: “When I saw this online, I thought, ‘Holy cow!’ I’ve never used one myself, but I could see using it to bust lugs on a semi.”
This sucker’s 51.7 cc two-stroke engine delivers 406 to 1,250 ft-lbs of torque — through a massive gear reduction and hammering action, we’d guess — via a 1″ hardened anvil. It also features electronic ignition and — be jealous, Trabant owners! — an “EPA certification.” It ships with 1-1/2″ and 1-5/8″ impact sockets and requires a 25:1 fuel mix.
Have any of you used this or one like it? If so, drop us a line and send us a picture of it in use — we’d love to hear about your personal experiences with it. And if you’re in the market, HF’s got it marked down to $300 from its normal $400 price tag.

This would be sweet for drilling curbs and catch basins.
Long time ago, an utility company left a similar one on my property. Though it was equipped with a drill. Once in a while I take it out for a test drive to drill some serious holes. While the power is nice bonus, the smell of gas in the morning is to die for
I certainly recommend it for the better outdoor jobs.
I don’t know what the hell I’d ever do with it, but thats’ pretty damn cool!
I know a guy who did a wireless repeater tower installation on a rocky outcropping in the middle of a remote island, using a gas-fueled drill to set the anchors in the rock.
I’ve also seen teardown crews use similar chop saws to take down TD-2 microwave waveguide in chunks. Gasoline has a much better power-to-weight ratio than batteries, and when you’re 200 feet up, coming down to change battery packs is a long-ass climb.
The weight on this thing has to be a killer for any reasonable amount of time, but if you don’t have the power you need on site it is a good tool.

Holy Crap, we have some huge stuff in the Army and other than busting track on a M113, Bradley, or M1 I cant see myself using this beast. Its
huge, and looks like it would snap a wheel stud in two like a twig. Man I
would just love to see this thing in action!.
It may look way big and too strong Pat, but realistically I’m wondering if it will have the power to remove Diesel Rig lug nuts. Really…. it may be…JUST……sufficient to do the job. Iv used the large air impacts used at truck tire repair shops, and while some were a zip…. others had to bang a bit then zip. So I was wondering as well about their power?
I need one…….not so much for me personally as I have air tools at home but at work we could use this from time to time to assemble various water main fittings/hydrants.
We have electric available on the tool trucks and I have used my electric impact there but electric and water are a bad combo and the aircompressors on the trucks dont work because of lack of maintenance and trained people to care for the tools.
We could use a smaller one since a 1″ anvil is a bit big and we could get by with a max of 450 ft lbs of torque anything tougher than that and we’d just grab the saw.LOL
I used one to change out a set of rails on one of my D-8′s.
It is a handful to operate all day, but I am 6’3″ and 320#, so I managed. Great tool for when you operate in the bush like me. After all 320 pad bolts, I noticed a crack in the bell housing. I wrapped a strap around it and it is still working.
fucking chinese pice of shit…. gone dead in 1 month….
I am currently working on making one for everyday mechanic, one that is powered by a weeder engine , this will deliver enough torque to remove lug nuts on a passenger vehicle ( cars and suvs ) , once i get the final touches done i will for sure post it here
Where to buy such wrench? How much is it? Is there anybody importing from China? I’m using a lot of product made in China, they are pretty good actually. Don’t just buy product with too low price.
