Ingersoll Rand 307B 1/4” Air Die Grinder, Straight, 28,000 RPM, 0.25 HP, Ball Bearing Construction, Safety Lock, Aluminum Housing, Lightweight Power Tool

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.

It's a nice good quality built tool. I got the aluminum housing version which I prefer due to being oldschool I guess, no other reason. I returned it because I didn't realize how small it was. I needed something more powerful so ended up going with the edge series.

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;-)

Good price.

Awesome size, awesome performance - only taking off one star because I had to take off the bottom hex fitting and put some sealant tape and thread locker on it and put it back together, cuz it leaked rather badly out of the box. No biggy really, but putting it in a vice with some rags to get the stupid fitting off was more of a pita than it really should have been, since the flat spot on the handle isn't really sufficient to do that with.Also, the speed adjustment doesn't make much sense. The screw either has it at high or low, there's no in between, and I'm not even sure at this point how far in or out the screw actually is, it doesn't really stop in either direction. Not very straight forward at all. To be fair, the high and low settings are pretty much what you would need, but I wish this could go a LITTLE slower, like 20% slower at the slowest setting.Still holds up to the ones my friends have that they paid double/triple for, so it's a great bargain, probably the best you will find on an air die grinder. Awesome for porting heads with.Can't comment on air requirements, I have a giant 60g air compressor pumping 90psi into it with no problems. After ~2 minutes straight of grinding at full, the compressor will kick on for like a minute and fill back up, whatever that tells ya.

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.

Nice very well made
