Expandable Rubber Drum Wheel for Diamond Abrasive Expanding Sanding Belts

Rubber Drums for Spindle Sander:Angled expansion slots through the heavy rubber rim allow the drum to expand when rotated; thereby locking the belt in place. Belts can be quickly changed by stopping the machine, slipping of the old one and sliding on the new. In use, the resilient drum surface flexes to the gemstones contour to quickly remove grinding flats. The convex shaped drum provides the cutting action necessary to remove scratches. Sold without belt. Maximum recommended speed is 1800 RPM. CAUTION: Do not run the drum without belts in place as damage to the rubber rim may result.
