5-1/2" Standard Nova Resin Bond Disc - 14,000 Grit

Nova Discs are ideal for polishing backs of cabs, nodules, geode faces, and similar flats as well as for sanding and polishing cabs. 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 1 ⁄4"-20 thread bolt is molded into their plastic back-up plate to fit our Gem-Makers and most other machines accepting that size bolt. The 4" Nova Disc is recommended for the BigFoot and Pixie, and the 5-1⁄2" is used on the Genie, Xpert and Titan. Nova Discs must be used with water. The price is for one disc only. Illustration is provided to show both sides of the disc as well as how it is attached.
