The shaft fits perfectly on my mini mill's potentiometer and the set screw holds it tight even with vibration. It looks a bit different than the photo but that's fine, it does the job.

Popped this on my mini lathe and the fit was perfect—no more wiggling the old plastic one. The knurled grip gives just enough friction for precise speed adjustments mid-cut.

Finally, a knob that actually fits my mini lathe’s potentiometer without any wobble or slipping. The plastic feels sturdy enough for daily use, and the set-screw design locks it down tight. Much better than the generic one I was using before.
