Ingersoll Rand Amoladora de troqueles neumática de 1/4 pulgadas 3107G

Really nice die grinder, built tough! I use it all the time in my weld shop without fail.

Works great.

Great little tool! Just wished I would’ve gotten one years ago.

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 …

GREAT value for the money. Kicks all my snap on products asses and costs a fraction of what they do. Only slight issue I’ve had is the top nut loosens over time and needs to be retorqued occasionally You can tell because the air leaks through it and the tool looses a lot of power. Simply retighten and it’s back to normal. Definitely would recommend to anyone

Very nice build quality, nice RPM's able to produce sparks from a flap wheel. It's clearly a high quality product and I love it but still unsure if I should have chosen the 1/2 hp model over higher RPM's.The 1/4 collet clamps down on my 6mm bits just fine though it needs to be tight.The inlet is an NPT thread 18tpi, I guess this is an american thing. We use 1/4 BSP aro couplers in the shop which are 19 tpi. I was able to run a plug tap through it and it seals perfectly.Not much in the box, just the grinder and spanners, no spare collets though my Campbell Hausfeld collets look identical and seem to fit.Definitely worth a look if you're after a nice high speed die grinder.

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

I've had this item for a year in July. I was told to buy the Kobalt ones from Lowe's from my coworkers so I did. They sold me on "life time warranty" I had one 4 months when it failed on me. I said no big deal I have a life time warranty. Took it to Lowe's and they gave me a hard time about the warranty after a few tries I got a replacement. That one failed 2 months later.i returned it got my money back and opted for a better brand so I chose Ingersoll Rand. I gotta say this thing has a huge amount of power compared to that kobalt. I've accidently dropped it from tables and from my welding machine (about 4' high) and still it remains strong. Sometimes I have to remove welds it tight spots where a grinder doesn't fit. With the right bit this thing just chews through the metal. I've been …
