8” Rubber Expando Drums
Use these 8"x3" expanding drums with diamond, silicon carbide, or other finishing belts for sanding and polishing gemstones. The expansion slots in the rubber rim allow the drum to expand when rotated, thereby locking the belt in place. The rubber drum is soft, resilient and durable. The drum surface flexes to the gemstone's contour to allow for quickly removing scratches even from flat surfaces. Belts may be easily changed by sliding on and off drums when machine is stopped. Ships with bushings to fit 1", ¾", ⅝" and ½" arbors. For use with your Titan Gem-Maker or other arbors with threaded shafts and retaining nuts. Drums must be mounted directionally correct to ensure belts won't slip when in use.
Also available in 6" diameter.
