Product description

The Hi-Tech Diamond rock/mineral disc kit comes with everything you need to polish rocks, minerals, synthetic material and metal. The diamond smoothing discs included in this kit ensures rapid removal of scratches and high spots on cabochons. Using a propriety technique, a high concentration of premium diamond 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 smoothing discs are guaranteed to out-perform silicon carbide sanding discs and other diamond compound finishing systems. Depending on the care and material you are working with, these discs on average will last for 100 to 200 pieces. They do not crack or peel either.

Our Tech-11 polishing pad and diamond paste included in this kit ensures a nice polish on your finished pieces. The Tech-11 polishing pad is made with high-density wool felt to replace leather pads. You must charge this pad with diamond compound before use.

All discs included in this kit come with a 3M pressure sensitive adhesive backing that easily bonds to backing plates, flexible discs and polishing heads. Discs also have 1/2″ arbor holes. Our sponge pads may be inserted under these smoothing discs to create a soft touch for cabochon work. Note: You need a backing plate to use these diamond smoothing discs and Tech-11 polishing pad.

If you plan on polishing glass and/or crystal, we suggest purchasing the glass/crystal disc kit.
