Review: I bought the 3/8 inch drive ONYX 1838 Astro first... then I bought the 1/2 inch drive 1832 Astro, the 1/2 inch Thor 1894 impact wrench, the Astro 222 angle and straight die grinders and the Astro 208 3" cut off tool. Have all of these types of tools; but, the ONYX brand is much better than the CP and IR tools for torque and basic functionality. The price was very reasonable for all of these tools, much less money for a much better air tool. I retired some of my older CP and IR impacts and die grinders and I am very happy with the ONYX brand. I had to grind away the recessed pocket in the die grinders for the handles... kept biting my fingers when I squeezed the lever; but, the die grinders and angle cut-off are quiet and very powerful. I have an IR, Air Cat and Earthquake 1/2 inch drive impacts that I have no need of now... the Thor is so much better for removing wheel lugs and such, lots of torque and power. I have a lot of all sorts of pneumatic tools, I am now sold on the ONYX brand. The little angled 1832 1/2 inch and the 1838 3/8 inch impact wrenches are very unique, they are not a pneumatic ratchet wrench, they will both take off wheel lugs as well as some of my big IR and CPs do. I did not think I needed any new pneumatic tools; but, after the purchase of the little 3/8 inch 1838 I realized I was not using the best. I use them constantly... may as well have the best and the price of all of them was very reasonable.
Review: Don't buy the 3/8 drive unit has way to much power,get 1/2 drive.Has alot of power,just as it says.I use mine lots in a truck shop!

## Features

- Extreme low profile, similar to the size of a credit card at 3.46” long

## Questions & Answers

**Q: Can torque be adjusted on this by reducing air or have adjustments on it**
A: Nope, it’s an air tool, but I use torque controlled deep sockets to control the torque. There’s also short sockets that are torque control but not regular short sockets, most nuts requiring torque need the space for the torque to be applied.

**Q: How do you connect the airline? The inlet on the tool has a cover that only spins and doesn't seem like it comes off.**
A: I assume u mean the black plastic plug that's installed at factory to keep debris out,pop that out and screw in correct air connector plug for coupler size u use, and always use pneumatic tool oil on first  use to help prolong life of tool

**Q: What's the smallest compressor needed**
A: It probably would work fine with a10-15 gal as long as it's intermittent use as with any impact long use needs the air behind it.I run 60 gal 230 v and it works great ,but I'm sure smaller compressor would do fine. .it's a excellent tool I really like it. Very powerful especially for the diy'er

**Q: is max torque the same for both sizes?**
A: The torque is the same but 1/2 inch gun work better on bolts
