Ingersoll Rand 320PG - Air Pencil Grinder, 1/8" Collet, Burr, 60,000 RPM, Inline, Rear Exhaust

Powerful and Precise Tool! This Ingersoll Rand air pencil grinder is an excellent tool for detailed work. It’s lightweight, easy to handle, and extremely powerful for its size. The 60,000 RPM motor provides smooth and precise performance, perfect for grinding, polishing, and detailed finishing. The kit includes a great selection of bits and accessories, all of which are high quality. I also like that it runs quietly and the rear exhaust keeps the workspace clean. Ideal for both professionals and DIY users who need accuracy and reliability. Highly recommend it!

Very impressed with the quality, low noise and minimal vibration. The value is great compared to buying a $500 Dotco

Great item to have around for a portable compressor. Air supply is limited, but to have access to this item remotely is very valuable. Great price too.

This is a great precision grinder. Its light and the vibration is low, so prolonged use should is not a problem. The small air hose keeps it light and easy to manipulate. At around 60,000 rpms its got plenty of power and easy to adjust. Overall its a great pencil grinder.

Had to replace my first one after just a few uses as the bottom started vibrating loose. The set screw would not hold, so turning it off became extremely difficult while the bit is spinning and the thing was coming apart in my hands. I made sure my line had an in-line 90psi regulator, too, so it wouldn't be overpowered. Submitted a warranty claim and had a new one sent to me. The second one started vibrating apart immediately. I returned that one a month ago and have received no follow up whatsoever. I confirmed with UPS tracking that they received it, too, so to get no response at all apparently means I wasted the money I spent on this. To be clear, this is a huge hazard - you can't turn off the grinder after use because the bottom portion turns with the slider. Sure, before it vibrates apart it works well and is much quieter than the cheap ones you can pick up on Amazon. But when turning it off becomes a danger, it's just a tool to avoid. The cheap ones never fell apart in my hands while in use. I really thought I was doing right by getting a well-reviewed, quality brand tool. But when two have the exact same dangerous issue, it's best to warn people and go buy something else.

Excellent grinder, no runout and is strong enough to remove material. I've used dotco and several other brands in the past, this one is just as good at 1/5th the price.

For the first hour it worked great ready to be a few but........After using for about an hour, the unit begin to vibrate apart, it separated from top and bottom, exhaust boot came off got extremely loud. It became difficult to use. I just put it back in my box and grab my dotco. Tried tighten it but, it keep coming loose. Gots potential. I work in turbine industry.

Good grinder for the price
