Astro Pneumatic Tool 1822 ONYX 1/2" Nano Impact Wrench v2-500ft/lb

This thing has saved me so much time from being able to fit into small spaces and it packs plenty of torque pretty much use this as my main tool pulling transmissions. I use this in spaces where I used to pull out an electric ratchet. I would recommend this with some universal impact sockets and you won’t have to pull out hand tools nearly as much.

Great product at a cheap price, haven’t had time to really use it. But I think it will do well in the diesel world. It’s loud and I like that feature. It screams when you squeeze the trigger. It throws a lot of power when needed.

I've stopped using an air ratchet completely, and this replaces many of my regular ratchet jobs (for loosening, mostly). This thing is amazingly small, and I think probably makes as much or slightly more power than advertised - when properly oiled. I thought Astro Pneumatic was one of those cheap-o generic names, but no way; this is *awesome*, especially for the price. And it's amazingly small. I bought it specifically to use with some bolt extractors on a rusty exhaust manifold in a tight space, but I've found that the light weight and small size makes it useful for lots of things. I picked up some impact wobble extensions from Harbor Freight (even HF can't screw up an extension) as well as several sets of the Astro low-profile sockets and the Gear Wrench x-drive pinless universal joint, and this thing is getting used everywhere.I specifically like the lever-style torque settings on the back; they make a real difference, unlike some impact guns where they should have one useful setting and several labeled as useless. I run on lug nuts with the thing set on 2 (out of 3) to keep the speed down a bit, and after just a couple of hammers, they end up just snug enough (60-ish ft-lbs) that I can set the car down and use a torque wrench the rest of the way. The light weight is great; I have a magnesium Snap-On 1/2" drive impact, and while it'll either remove or break off anything I'm gonna encounter on regular automobiles, it does get a bit heavy when you're upside-down twisted around a driveshaft with dirt falling in your face. This thing, in combination with a Flexilla high-flow swivel coupler (you *need* high-flow fittings for an impact gun, and that swivel is easily the best-flowing one anyone makes) can get into a tight space and not make you feel like your arm is going to fall off. I replaced an alternator bracket oil gasket on my BMW N62 recently (which is about a 12 hour job), and used this for pretty much the whole job. It saved a ton of time and effort compared to trying to use ratchets, snaked around all the stuff jam-packed into an E60 engine compartment.As some others have mentioned, it's a tad loud, I guess, but the big Snap-On is far louder. Really, I consider this gun average for an impact gun. The noise is not as annoying as my air ratchet, which, as mentioned, I no longer use.It's also really well made. The picture makes it look like maybe plastic, but it's a textured finish on a metal case. The trigger feels good, the balance is good, the "shiny part" looks sort of like nickel or black chrome and is well machined, and overall you can tell that it's well-made by people who give a damn about their product. I've banged it around a little in the weeks I've been using it, and while there are a couple of little scratches, it's held up well. I've also sold a few friends on this thing, because I can't stop talking about how much I like it. :D I would've been happy if I'd paid $250 for the thing; the fact that it typically has a 2-digit price is just amazing to me.Buy one. You won't be sorry.

I got burned before with a cornwell stubby air impact. The thing was gutless and therefore absolutely useless. This astro gun is much smaller than the cornwell and packs some serious punch. It rivals my matco 3/8 gun that is twice the size. Believe the reviews, this thing for it's price is unbeatable.

This little impact has quickly become one of my favorite tools in the shop. It’s smaller in length than my Milwaukee M12 “stubby”, yet it’s actually more powerful than my Snap-On CT9010 mid-torque. Despite the power, it doesn’t whip you around when breaking stubborn fasteners—it delivers torque smoothly and effectively.The grippy texture of the housing plus the rubber grip sleeve make a huge difference in real-world use. Even with oily hands, it stays secure and comfortable, which gives you more control when working in awkward positions.For its size, the power-to-weight ratio is outstanding, and the ergonomics are spot on. This is an absolute win for tight spaces or anywhere you don’t want to wrestle a full-size impact. Highly recommended.

My girlfriend complained my reviews were too long. That hurt a little bit, because I enjoy taking the reader on a journey with me, and in the end hopefully you get a good product review as well as maybe a little laugh along the way.Anyways, I like to believe I'm open to constructive criticism, so here's my new review format--all the facts up front, with all my blah blah blah mumbo jumbo at the end. Hope you enjoy.Pros:--Incredibly small impact wrench-- Great power-to-size ratio--Gets into really tight spots--Affordable--You can carry it in your back pocketCons:--Maybe not a fair con, but it’s not a replacement for a full size impactConclusion: Great impact that would make a welcome addition to your tool box.Here’s the blah blah blah part:I’m not a professional mechanic, but I love working on my car and the cars of friends. I’ve recently been phasing out my use of air impact wrenches in favor of cordless models which has worked out great. Unfortunately, the smaller cordless impacts (at least the ones I have) just don’t have the oomf that a comparable sized air impact does. That’s where this Astro impact really shines.I learned of this stubby impact from watching you toob videos of South Main Auto Repair. If you’re a professional mechanic, probably the last thing you want to do is watch another mechanic do their job, but for me, I can spend hours watching that stuff. Anyways, Eric from the channel has this Astro impact and spoke highly about it, so I thought I’d pick one up and try it myself.Wow, this thing is small. You can really squeeze this thing into some tight places. Heck, you know you have a small impact gun when your deep well socket is longer than the gun itself. Of course the first thing I used it on were my lug nuts. They’re torqued to 90ish pounds and no surprise it was able to get them off, but it did have to hammer on them for a moment—it definitely wasn’t instant. It has its limits….it’s not going to remove the nut from a trailer hitch ball (tried it), but to be fair, that’s not really what this is designed for.Where this thing really shines is when you have your head crammed in your wheel well and you’re working on suspension/brake components. If you’ve got a universal swivel socket on this thing, there aren’t many things you can’t reach with it. Remember the scene from Kill Bill where Uma Thurman punches her way out of a coffin? Yeah, using this impact gun is kind of like that.One of the biggest reasons I bought this was for an upcoming timing belt replacement on my car. I needed a stubby impact that would fit between the crank pulley and radiator. This definitely fits, but I haven’t done the job yet so I don’t know if it’s got enough hootzpa to take the crank bolt off—I think the spec says it’s tightened to 180 pounds….but we all know how crank bolts are sometimes. For now, I’m giving it a rating of 4 stars, but if it takes off my crank bolt, I’m updating my review to give it 50 stars. Regardless of how this handles my crank bolt, I still highly recommend this impact gun.
