3107G

I've always preferred IR for my pneumatic tools. They've never let me down. It's a great grinder and has the power if you've got the PSI and CFM's. It doesn't have a button for locking the collet so you'll still need 2 wrenches to loosen/tighten the collet. There is no speed adjustment. It feels good in the hand and functions as expected. I'm running it on a 20 gallon compressor that puts out 6.1 CFM's at 90 PSI. It eats up a lot of air so my compressor being only 20 gallons runs constantly but never drops below 90PSI when using the tool. But I don't have an ordinary 20 gallon compressor either, I've upgraded pulley sizes on my pump and motor, hi-flo couplers, copper tubing sizes, etc... Most compressors my size don't have the capability to run this tool for more than a limited amount of time. You'd probably want at minimum a 30gallon compressor for this tool that puts out 6cfm at 90PSI.

quality grinder. i have replaced several cheap grinders in the past with this unit

Nice value and works well, definitely recommend!!

Basically, this tool works well. It’s inexpensive. Yes, there are unknown brand Chinese tools that are even cheaper, but since a semi professional air die grinder like this costs close to $100, this isn’t expensive, though some reviewers seem to think it is, by measuring price from the cheapest as being normal. But having said that, the wrenches are too short. I know they saved a few pennies on the metal here, but these can’t tighten the collet enough. I found that when pulling the tool, the cutter would slowly move further out of the collet. When pushing the tool, it would slowly move inwards. Very dangerous! I had to use longer wrenches to properly tighten the collet. Then it was fine. Like all collets, you have to leave about 1/8” of the collet on the bottom empty. Otherwise when you try to remove the cutter, it can become stuck, and since you have to push it in to release the cutter, you won’t be able to. I mention this because if the cutter moves to the bottom of the collet because it wasn’t gripped enough, you might have problems getting it out again.

So I read some of the negative reviews on this product. Don't believe it. If there was a problem, it had to be one offs. Life is not perfect. I used this die grinder to sculpt my 02 silverado wheel well repair work. I used it to get to small places to grind down to metal while removing rust. I used it to sculpt the Bondo Glass fiber glass filler down by 1/4" or less to prepare it for the standard bondo filler to get it ready for painting. This grinder performed better than I expected. In fact, I just added it to my list of valued tools. I suspect most who purchase this tool will be using it on auto body work. So if you are looking for a great die grinder for your auto body repair project and don't want to break the bank but want quality and performance, this tool is for you. Good luck with your project!

Buena calidad

I'm a mechanic by trade so I use these all the time. Easy to control the speed and at full speed they get moving. Nice and durable too. Can handle a drop and keep on cutting. Great deal for a great price. Very happy with this buy and would definitely recommend.

Using this to fit and tight areas to cut metal has been working great needs a little bit more air pressure than what it is asking for but does a good job. Very smooth and precise especially if you get a quality cutting wheel/disc

Excelente equipo

Excellent rapport qualité prix Il est fait petit pour des endroits restrains Il est quand même fort pour la grosseur

good

Easy to hold, easy to use, just like all IR tools

Really high quality definitely can’t go wrong with any Ingersoll Rand tools
