Well worth the price
Really, really nice die grinder. Very fast, smooth, and tons of power. Bearings and gears are all tight. Add a double swivel air connector, and you will love it.

Feels like a glove
I am a professional mechanic, many of my pnuematic tools are Snap On brand. I have used and experienced Ingersol Rand over the years though and I believe they make solid options that are more affordable. A right angle die grinder has been on KY bucket list for quite some time, so when I saw this I got it. It feels good in my hand and functions well, it looks pretty clean as too. I will use it with plastic attachments mainly for cleaning off old gasket materials.

If they put it on sale again, I’m buying another one
This IR die grinder is built for long life, has plenty of power, operates at high RPM, feels good in your hand, and was at an excellent price point. I’ve used it for over 20 hours already, and haven’t found anything bad about it, other than I hate the locking paddle switch. I’ve removed the locking mechanism so no more problems;-)

Seems to use less air to run
I’m glad that I went with brand name tool because it seems to use less air to run. Some of cheaper units consume so much air that compressor can’t keep up. I’m comparing with HF brand tools. So far in testing this IR die grinder is working perfect. I use it in restoring my older CJ Jeeps to get in corners with either 2” discs or burr grinder attachments. This is a handy tool to have when working metal or most any materials. I would recommend buying.
