Astro Tool 1833 3/8" Nano Flex-Head Angle Impact Wrench - 400ft/lb

I should have bought one of these years ago. It's fairly lightweight, has a swivel and flex handle with over 180 degrees of flex, is surprisingly powerful for its size, and really fits into some tight spaces. It was invaluable replacing the suspension airbags and shocks on my diesel pusher coach. It's a great tool for a very reasonable price.

Had a matco one that lasted for years until I broke the direction switch. Bought this one knowing it was the same for much less. It doesn’t replace a full powered 1/2 impact but it can fit in places i would have never tried before. It is the go to for removing sway links or fasteners I fear breaking. With a swivel socket it is comically underpowered and totally worth it. It can still take off most lug nuts.

This is a great tool and life saver I recommend it to anyone with an air compressor, especially if you’re doing automotive work.

This may be the impact tool that you want, when most normal impact wrenches won't fit because of depth. Designed for brake work. But useful for many other purposes. The handle can be flexted/bent to clear obstructions. There is also a 1/2" version. I went with the 3/8" because 3/8" sockets are often shorter than 1/2" sockets and tight spaces are the reason for buying this too. Astro Pneumatics also makes some special, low depth impact sockets, which I plan to get a few english and metric sets of, as soon as I see a good enough sale price. While the tool is very low depth, with the handle, etc. it isn't otherwise smaller or lighter or lighter than some other impact wrenches. At 400 ft/lbs. the torque isn't particularly high. These are the trade-offs for making it small enough to fit in close clearance areas. For tight areas, you may also want to consider the model 1831, which is a bit thicker, but may work in some areas where the handle on the 1833 still gets in the way, even after flexing the handle. It also has a bit more torque at 445 ft/lb.

Got this after seeing good reviews online for the tool. I've got a small compressor (2 gallon + 7 gallon auxiliary tank), so I don't have a ton of air to run air tools for long durations. However, this setup with a small-ish air impact works well for general tasks, like brakes and small fasteners. I'm quite happy with the impact, partly due to the flex head being able to reach a lot of areas a normal impact wouldn't, and for the reasonable power it provides. I do wish this tool had a bit more variability in power, but otherwise, it's been fine as an on/off switch type tool. Overall, I'd highly recommend, especially when it drops to ninety-ish in price.

Got it a little over a year ago and this air wrench is VERY nice to have around in our shop. I got the 1/2 inch but it still fits pretty much everywhere we want to use it on, it definitely saves doing some yoga if you were using a normal air wrench when pulling beds/engines/transmissions/body mounts/etc. I’ll also mention that it is pretty light too while still keeping the speed and power it had when we first bought it even after over a year of using it fairly often (probably 1-3 sessions with it per week if I had to guess) so it’s pretty durable id say though I haven’t tried any other Definitely a quick to set up and strong little tool to have around id recommend it

I love this thing. I am a diesel mechanic of 15 years and I was turned on to this thing when I saw a smiliar make on the matco truck. I am here to tell you its the exact same design for waaaaaaaay cheaper. I saw it on the truck and to my surprise it was $380 that was on speacial!!! so I said screw that I am gonna see about it on amazon and sure enough here it was. great product for getting those pain in the butt bolts that are hard to reach. you can twist the handle to make it easy to pull the trigger and you can flex the head to fit in that spot that is near impossible to get back there with an impact gun. I recommend this product to all my fellow mechanic buddies cause it really is a great add to the tool box. 400 ftlbs of breakaway torque is superb.

It’s a nice and well built tool with very smooth operation and also very quiet. It definitely has a place in my tool box and will be useful for many things. I only gave it 3 stars because there are two things I don’t like about it. 1. It really doesn’t have much power for a 1/2 inch drive air tool. I haven’t had much luck removing the bolts from caliper brackets like many of the other reviews have commented on it being good for that. Now in all fairness to the tool, I work in the rust belt and a lot of the vehicles I work on have larger caliper bolts (19mm to 21mm) if I use in on a Hyundai with 14 mm bolts it works fine. The other thing I really don’t like is the exhaust. It discharges out of the side and if you have any trace of air tool oil you are going to get blasted in the face with oil, even if the exhaust is not aimed at your face, it will blow dirt and dust out of the wheel well and into your hair or on your clothes. I feel it’s necessary to to point this out because none of my other air tools have this issue.

Powerful tool

Very handy impact. Great for tight spaces when on creeper and also wheel wells. Tool is far lighter than my reg impact, not as much power but will work for most chassis fasteners that aren't terribly seized.

My consistent go to for smaller work areas that my large impact gun can't access. Love the movable trigger and being able to angle the head. Great tool.

Great quality product

It is MUCH better than Milwaukee m12 series impacts and it has PERFECT spot reach capability unlike solid body impacts. STRONGLY recommended! The only drama is weight if you have any tendon,joint,muscle etc. issues it may be hard to operate for long hours other than that it worths the money. Combine this with u joint swivel impact adapters and literally can access everywhere.
