Astro Tool 1834 1/2" Nano Flex-Head Angle Impact Wrench - 400ft/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

Very Pleased with fit

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.

Great impact for the price. It seems a little underpowered in certain applications but in odd ball situations, the compact size paired with the ability to flex the head gives you great use. On transit buses, the torque rod bolts are usually very tight and at tough to reach spots to get straight on with a normal impact. This impact has enough oomph to rip those bolts right out which is surprising. Is it a direct replacement for a normal impact? No.. it’s an addition to the toolbox with its own place. I would highly recommend this impact or the capri variant and you won’t go wrong.

Great tool

Matco wanted too much for this same exact tool, works great

First things first—grab a T25 torx bit, open the impact mechanism, and clean out the excess grease at the edges of the housing. These things are way over-lubricated from the factory and the impact mechanism can't spin freely with all that grease in the way. Be sure to leave grease on the anvil and hammers where it's needed then reassemble and make sure the anvil spins freely. Once you remove that grease you'll be rewarded with an astonishing amount of power for such a small impact wrench. That being said, this shouldn't be your main impact. Sure it can spin off most passenger car lug nuts. But a regular impact will do that better and more comfortably. This is a special tool for those hard-to-reach or awkward bolt locations where the alternative is a manual ratchet or wrench. But when you need it, you'll appreciate just how amazing it is. Important note—pay attention to the exhaust port. Because of the flexible head, you might find yourself staring right at it. If you forget, you'll be instantly reminded with a powerful puff of compressed air mixed with air tool oil.

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.
