Review: Great air tool - This thing has become the go to tool for cutting straight lines in metal. Super easy to control and follow out traced lines. Very clean cuts.
Review: Astro 409 Quick Change Cut Off Air Tool - 3/4 HP Uses 4" Disks - Very Powerful 4" by 3/4 HP Pneumatic Cut Off tool. Astro Part # 409. I've had time to run this tool for a better tool review. Simply said it is kick butt powerful. Didn't bog down even though I got into it with some thick metals. Really pleased with the grip, performance and fit and feel. My hands are worn tough and calloused and I'm sure some mechanics know what that means, we loose some feeling in our hands now and again. This cut off tool is solid in the grip and easy as heck to use and I like the Quick Change disk feature, A Lot! It's Hard Work - Made Simple. If you're looking for or thinking of getting a new Cut Off tool - give this guy a shot. You will like the warranty coverage too. Astor stands by their tools.

## Questions & Answers

**Q: what is maximum cutting depth ?  diameter of motor body?**
A: You get about 1.5” of cut depth til the collar of the shield hits your material. The diameter of the motor body isn’t huge but I’d say around 2” or so. This thing is extremely well balanced, and accepts 4” cut offs. I was extremely happy with mine! The trigger lock is comfortable and easy to engage, you do t have to try a couple times to flip the lock. I’m a custom car builder and So many times you need a cut in a tight spot and using the traditional pneumatic cut off tools you can’t get there, but this tool helps make it easy.

**Q: Where is this made?**
A: Good morning. This is made in Taiwan.  Thank you.

**Q: How much does this tool weigh?**
A: It weighs about 1- 1 1/2 lb

**Q: Can i use 3" wheels?**
A: you can use them, but since it is a machine that takes a 4 inch cut off wheel, and it says "4 inch cut off wheel", why do you have to ask stupid questions?

### ⭐⭐⭐⭐⭐ Astro 409 Quick Change Cut Off Air Tool - 3/4 HP Uses 4" Disks
*by T***C on November 7, 2015*

Very Powerful 4" by 3/4 HP Pneumatic Cut Off tool. Astro Part # 409. I've had time to run this tool for a better tool review. Simply said it is kick butt powerful. Didn't bog down even though I got into it with some thick metals. Really pleased with the grip, performance and fit and feel.

### ⭐⭐⭐⭐⭐ Clean, straight cuts but you have to slowly feed the disk
*by K***N on May 2, 2026*

I appreciate the prior reviews as I was not surprised by the performance. I've used Astro pneumatic tools and led lights for years and they make quality stuff. I do personal car restoration and repair. I have a 5hp 2 stage Quincy compressor (forget the SCFM ratings) and I need about 80# on the gauge for this to go through 1/8" mild steel sheet. It DOES take a bit of time BUT it does clean cuts IF you don't dig into the piece. The 4" disk also helps, IMO. This replaces my ancient HF side cutters which are quicker but not as easy to control as the Astro. Overall, excellent tool for me.
