3M Diamond Sanding Belts
Diamond Sanding Belts for use with expanding drums and belt sanders provide a relatively economical way to enjoy the benefits of diamond abrasives. They have the flexibility of standard cloth belts along with the durability and fast cutting action of plated diamond wheels. They come in common grit sizes and a variety of belt sizes to fit most expanding drums. The metal bonded belts are best for grinding and sanding while the resin bonded belts are better for polishing.

Expanding Drums
Use expanding drums with either diamond or silicon carbide belts for sanding and polishing gemstones. The flexible surface of the drum conforms to the shape of a stone when run at low speeds, and at higher speeds hardens from centrifugal force to provide a surface for grinding. The pliable rubber drums expand during rotation, holding the belts firmly in place. Belts are easily changed by sliding on and off drums when machine is stopped. Come with bushings to fit 1", 3/4", 5/8" and 1/2" arbors. For use with arbors with threaded shafts and retaining nuts.
