JET 1/8-Inch Pneumatic Micro Die Grinder, 70000 RPM (Model JAT-410)

From the moment I opened the box I knew I was in for real treat! ! Even the box opened so smooth that I almost lost my breath! ! ! As I plugged in the air connection, I could see the hose starting to swell and felt the sensation of pressure building. Then I inserted the cylindrical stem into the collet and using a little force I could feel the Collet squeezing on the shank of my tool until it was delightfully tight. As I slowly began to twist the and turn the control sleeve, I could hear a low pitch whine.... not to get to excited I let it whine for a moment or two before applying pressure at full load......OMG OMG OMG! ! now all I hear is low volume high pitch screaming...... It was as though I could feel the air flowing past my face like a gentle breeze thru the tall Alabama Pines on a warm Gulf Coast spring afternoon! ! ! Even though it's a small cylindrical shape this tool packs quite a punch! ! ! I try to use it as much as possible simply because it is sooooooo gratifying! ! ! I definitely recommend this tool and actually intend to purchase another one.

I bought this to do little touch ups on all various materials using all different kinds of tips. Let me tell you something, this little thing is POWERFUL! Normally I dont purchase too many air tools since electric tools are blowing them away (All my other tools are Milwaukee fuel). However, this little thing beats/compares to my bigger die grinders even when set on a lower airflow. Just remember that this requires a decent bit of cfm so make sure you have a compressor that can handle it. 10/10 would recommend and buy again

Ive had this tool for over a year now.. its important to feed it dry air and use air tool lube. Ive done many jobs with it now and it works great.

This one has too much vibration. I should have popped for another Dotco.

I've been working in tool and die for a handful of years now, and i've always just chewed through cheaper pencil grinders because i figured you'd have to spend a good chunk of cash to get a pencil grinder that was noticeably better than say, an neiko or an astro pnumatic. after my last one finally went kaput, I decided it would be worth tossing in a little extra cash to see if this one would be any better. Even though I spent the cash I was still skeptical, because the housing looked exactly the same, and I was pretty sure they were the same thing with a different stamp on the outside. Luckily that turned out not to be the case. This is definitely of a higher quality, the housing is a heavier duty, and it reaches higher rpms, and doesn't get hot like the neiko and astro tended to (yes i kept them oiled, I promise) It took a second getting used to it, because the burrs would really dig in to harder steels so my handwriting was a bit messier while I got used to it. Long story short, yes it is better than the cheap ones. No, it's not as buttery smooth as a 500 dollar one. Worth the extra 100 bucks. It's put in about as much work as any of my others have, and it still running like it was on day one.

Does the job nicely.

Aviation Mechanic, I do a lot of fiberglass and sheet metal repair and this one and the 45 degree one are my go too probably should oil them up as there heavily used and about a Year and a half old but hell man jet makes some great stuff

Absolutely amazing tool for the money! I have put in about 60+ hours of use with it. So far hasn’t skipped a beat! I would definitely recommend and purchase this again.
