4" Nova Resin-Bond Discs
Nova Discs by are ideal for polishing the backs of cabs, nodules, geode faces, and similar flats as well as for sanding and polishing cabochons. They have a soft, rubber backing and are slightly convex (domed) so that under pressure of your stone, they provide an even polishing surface in the middle area often missed with other methods. A standard ¼"-20 thread bolt is molded into the back-up plate to fit Diamond Pacific's Gem-Makers and most other machines accepting that size bolt.
The 4" Nova Disc is recommended for the Bigfoot and Pixie. Nova Discs must be used with water.
5½" Nova discs are also available.
