The Expandable Rubber Drum Wheel is designed for use with sanding or polishing belts to obtain smooth, polished stones. The wheel features angled expansion slots through the heavy rubber rim, which allow the drum to expand when removing the belt in place.
The soft, pliable rubber expands during rotation to grip the sanding or polishing belts, and belts can be quickly changed by stopping the machine, slipping off the old one, and sliding on the new.
The resilient drum surface flexes to the gemstone contour, quickly removing grinding flats. Its convex-profile provides the cutting action necessary to remove scratches.
The expandable drum sander wheel expands when the machine is turned on, holding the sanding belts in place during operation.
The expandable drum sander wheel is sold without a belt, and the maximum recommended speed is 1800 RPM. Running the drum without belts installed may damage the rubber rim.
