Accusize Industrial Tools 1/8" Miniature Precision Air Die Grinder, AT00-3170

I love it the only thing that I didn't like about it was the collet 2 special wrenches that you have to have and keep up with

I've used this daily in a toolroom/machine shop for over a year. It functions just like it did when I bought it. I do oil it before I use it every day (very important!!) I've had $100+ brands that have seized up after a couple of years, so I thought I'd try a $30 version. It does the same job as the Chicago Pneumatic. When this one locks up, I'll buy another one.

Tool was mounted on a lathe tool holder for grinding some rubber seals that were too soft to otherwise cut. Touched tool but off to a known dimension and made some cuts only to find out that the part was now way oversized. Upon inspection, the tool, 5/8” from the collet measured .017” runout. Removed tool to inspect fur burrs, debris, etc. and reinstalled.Same issue. Poor quality of collet.

Nice grinder. Just as good as the one I paid 3 times as much for. Collet runs dead true, no abnormal vibrations.

Nice product for the price

Had to order two and both were junk. The rotary switch was frozen stuck. The inlet was crooked and the cheap plastic snapped the minute it was touched.

knob would not turn to adjust air flow. The braided hose is of poor quality - very stiff.
