Customer Reviews (4.8 / 5 · 5 reviews)

Isabella U. ★★★★★

The knurled grip on this knob gives a nice tactile feel when adjusting speed mid-cut, and it threaded onto the shaft without any wobble. Much better than the smooth plastic original that came with my mill.

Evelyn G. ★★★★★

The metal shaft fits perfectly into the mill's existing socket, and the whole assembly tightened down without any play. Really like the solid feel when turning it to dial in RPMs.

Michael L. ★★★★★

The knurled grip makes speed changes feel way more precise than the original smooth knob on my SX3.5. It seated firmly on the potentiometer shaft with no wobble, and the tactile click stops are a nice touch.
