## Questions & Answers

**Q: Is this the one where you can move the shield without any tools?**
A: The shield on the angle grinder is not removable without tools.

**Q: Can i use a blade with a 7/8 opening?**
A: Yes, the 345MAX comes with a spacer to use abrasives with a 7/8" center hole.

**Q: What size  is the arbor?**
A: Model: 3445MAXFree Speed rpm: 12000Arbor Size: 5/8"-11Wheel Type: Type 27Wheel Diameter in. (mm): 4.5 (115)Maximum Wheel Thickness in. (mm): 1/4 (6)Guard Part Number: MG1-106-45See: http://www.irtechpubs.com/ir_pdfs/Tools/Finishing%20-%20Surface%20Prep/Air%20Grinders/45654522_ed1.pdf

**Q: What size of compressor you need to run this tool?**
A: Though it's not listing the CFM consumption. I know the tool should run at 90 psi. You may be able to get away with a little 36 gallon compressor for short bursts. For doing long grinding and body work your looking at minimum a 50 gallon compressor to an 80 gallon. Again it depends on the CFM of your compressor pump as well.

### ⭐⭐⭐⭐⭐ Great product
*by R***B on June 9, 2025*

We run these a lot. They are well built and give us very little problem. The build quality is excellent. We will continue to buy these.

### ⭐⭐⭐⭐⭐ Excellent !
*by J***T on March 8, 2021*

Fantastic so far use it every day only issue was the Guard ,had to take it off it needs to be adjustable . Out of the box its only able to take a hard wheel , all the years I have been welding I built up a nice assortment of grinder parts and was able to put a sanding pad on . $80.00 for $200+ grinder that had a "Blemish" I couldnt find, is money well spent

### ⭐⭐⭐⭐ Perhaps a little pricey but we'll worth it It's very comfortable and designed for a purpose
*by P***S on May 14, 2016*

Considering that I've been in the metal trades for almost eighteen years, I would think my opinion would be beneficial to many when thinking to purchase a pneumatic angle grinder.Over the years I've experimented with an infinite number of pneumatic angle grinders. I'm certainly not green when it comes to the various brands available, and how they produce on the shop floor.The Ingersoll Rand brand has always made a reliable and we'll constructed product. And the 3445max is no exception. Perhaps a little pricey but we'll worth itIt's very comfortable and designed for a purpose. The lean body of the grinder allows the operator to use it with eaze over longer periods of time, without the same fatigue brought on by bulkier grinders. Vibration and noise is very low, and the amount of power it produces is more then sufficient to remove material, sand and finish. Throw on a Walter Zip Cut and you have yourself a impressive grinder.However, a truely unexplainable flaw on this grinder comes from the amount of work needed to change your discs. There's certainly no quick change here. You need your entire tool box when it's time to change a disc. Wrenches , Allen keys and 2 sets of arms for starters. Aside from that it's definitely worth a go. As a Millwright working in heavy industry this grinder gets put to use and it certainly holds his own . Thumbs up
