Astro 1822 1/2″ Nano Impact Wrench

This tool is very lightweight and packs a serious punch. I’ll keep my review short and simple, but here’s the gist of the review:

  • 450 ft./lbs. of max torque
  • Extremely short profile, full length of less than 3-7/8″
  • Incredibly lightweight at 3.0lbs
  • 3 forward and 3 reverse settings
  • Innovative twin hammer design

What I like:
It’s solid, compact, and has tons of torque for its size. It’s also cost effective, and it’s honestly not very loud for what you’re getting. This tool with take most things off and provide access where you never thought you could reach. I checked for any excessive play and I found none; the tolerances felt great. It also comes with a real comfortable soft rubber removable grip, and that’s definitely a nice touch. This impact is also significantly lighter which was a nice plus.(we have written a guide about  chainsaw).

What I don’t like:
the trigger is a bitter stiffer in response than I’d like, but there’s also 6 different settings to pick from that negates that idea. The switches are also not workable with one hand currently, but the good news is – they are definitely easy to tell when you’ve firmly selected the setting.

Great tool.
It would be nice if any piece of documentation discussed torque values.
I tightened lug nuts on setting 1.
Then I tightened with a torque wrench and I got an additional 10° of rotation.
So, I’m guessing setting 1 is about 85-90 ft-lbs.

First I will tell you I had purchased a Central Pneumatic 1/2 Impact from Harbor Freight. And I will not criticize it. For the money and if you are not planning to use it for more than a 3/8 inch bolt, it will do fine if the bolt is not to tight and be aware, it uses a lot of air. But it would not remove my mower trailer lugs, or my Scag mower blade 9/16 nuts. It would beat and beat, and the air compressor would kick on and run and run. I have a Porter Cable twin cylinder with a 20 gallon tank on 120 Volt. I thought my be my compressor was not big enough. Then it all change when I decided to buy this Ingersoll Rand 231C Impact wrench. I had ordered a new hub for my trailer and new blades for my Scag mower and I could not wait to give this Ingersoll Rand a try.
I just used the 231C for the first time since arrival and it’s already everything I had hoped for and more. My brother bought me my first impact for Christmas probably 10 years ago and after trying to use to rotate my truck tires was a disaster. It wouldn’t even remove one lug hand torqued to 100 ft lbs. So after doing some research the Ingersoll-Rand name kept coming up and with the very favorable reviews and I made my choice.I went back out today to try and rotate again and every single lug nut came off with ease. I have a 15 gallon Craftsman compressor, nothing special, but it only ran 3 times between removing and re-torquing 6 lugs per wheel. Regulator was set to ~100 PSI with 100′ of 3/8 hose.

I started the lugs by hand after moving the tires and set the tool to 2. I set the truck down and pulled out my torque wrench and set it to 100 ft lbs. Every lug nut was at least 100 ft lbs. Awesome.In addition, the impact itself has a really great finish and the adjustments are notchy and precise. I do have an in-line oiler/dryer so I did notice a small amount of oil coming out of the exhaust, but that’s to be expected.

I’m been around shops all my life and I have seen and heard the Ingersoll Rand name a lot so I wanted to see what it would do. I got my mower jacked up and put the 15/16 socket on the impact wrench and kit the trigger. Boom, where did the nut go. I hit the other two blade nuts and it was just boom and they were off. I changed three blades in no time and my compressor never kicked on. This is a great wrench. This thing is powerful. And a good looking wrench. I am very happy I purchased this tool. I wish I had bought it first.
