Diamond smoothing discs

SKU: 30-021


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.

Great for finishing more technique sensitive

Great product for smoothing and polishing after using the diamond disks. If you try to use them for material removal they wear out significantly faster. Buy a couple finer diamond disks instead.
