Emily ★★★★★

I was worried the 1mm thickness might be too flimsy, but it's held up fine during my last few projects on the mini lathe. The 27.2 mm center hole fit perfectly on the spindle without any wobble.

Thomas ★★★★★

The 56mm diameter is exactly what my 7x10 needed, and the thin 1mm profile lets it sit flush without any wobble. Worked on the first try—no filing or adjustments required.

Sofia B. ★★★★★

Fits perfectly on my 7x12 mini lathe's spindle tachometer, no modification needed. The 56mm diameter and thin 1mm profile are exactly as specified. Got it running in under five minutes.
