Covington Expandable Drums

Covington Expandable Drums have angled slots through the heavy rubber rim which allow the drum to expand when rotated, thereby locking the belt in place. Belts can be quickly changed by stopping the machine, slipping off the old one and sliding on the new one. In use, the resilient drum surface flexes to the gemstones contour to quickly remove grinding flats. Run at a maximum speed of 1725rpm.
