Finally, a knob that actually stays tight on the shaft instead of slipping like the old one. The set screw design gives a much more secure grip, making speed adjustments precise and reliable during operation.

The replacement knob fits my HiTorque bench mill perfectly, and the spline alignment with the shaft was spot-on from the first press. It’s a solid, snug grip that doesn’t wobble during speed adjustments, so I’m glad I didn’t have to fuss with epoxy or set screws.

Had to replace the original speed knob after a small mishap, and this one slides right onto the shaft with a snug, secure fit. It's got that same ribbed texture for a good grip, and now I can dial in the RPMs precisely again.
