حلقة ضبط، مغزل 8.5×20 مخرطة منضدية

The set screws have a satisfying bite when torqued down, and the 4mm key alignment takes the guesswork out of centering the ring on the spindle. Feels more robust than the plastic alternatives I’ve used before.

Slide that ring onto the spindle and the flat point set screws bite in solidly. The steel feels sturdy enough to keep the adjusting block precisely where I need it.

The keyway alignment with that 4mm key made installation dead simple — it slid right over the spindle and locked down tight with the set screws. No wobble at all once it was snugged up, exactly what my bench lathe needed.
