Are ideal for polishing the backs of cabs, nodules, geode faces, and similar flats as well as for sanding and polishing cabs. The Nova Discs have a soft, rubber backing and are slightly convex (domed) so that under the pressure of your stone, they provide an even polishing surface in the middle area often missed with other methods. A standard 1/4 – 20 thread bolt is molded into their plastic backup plate to fit most machines made today. (Adapters are available separately) Nova disc must be used with water.
