Diamond smoothing discs

SKU: 30-021


Important purchasing note: These smoothing discs are sold individually.

Hi-Tech Diamond diamond smoothing discs ensure rapid removal of scratches and high spots on cabochons. They also smooth large, flat areas in channel inlay work and are perfect for smoothing, refining and polishing a wide range of material such as glass, gemstones, synthetic material and even metal. These diamond smoothing discs come with our All-U-Need rock/mineral and Slant Cabber rock/mineral lap machines.

Using a proprietary technique, Hi-Tech Diamond diamond smoothing discs use a high concentration of premium diamond that is loaded onto each disc to provide an extremely aggressive grinding rate yet leaves an exceptionally smooth surface finish. Each disc is color-coded to easily determine what grit the disc is. These diamond smoothing discs are guaranteed to out-perform silicon carbide sanding discs and other diamond compound finishing systems. They do not crack or peel.

6"- and 8"-diameter diamond smoothing discs are available. All discs come with a 1/2" arbor hole and 3M pressure-sensitive adhesive backing that bonds to backing plates, flexible discs and polishing heads. Optional sponge pads may be inserted under these smoothing discs to create a soft touch for cabochon work.

Please note: You will need a backing plate to use these smoothing discs.

3000 grit grinding disc

I've tried other 3000 grinding disc and all they did was scratch up the rocks. The one I bought from you works perfectly. A little expensive but well worth it. Thank you

The product exceeded my expectations. I work on turquoise, variscite, and opals. The surface polishing was consistant and vibrant. Overall a very good product.

Worked like a Champ
