Selection and Compatibility
After a gemstone or cabochon cutter, custom body jewelry carver, or other lapidary artist creates a preform for a carving with sintered carving burs or your preferred sequence of carving bits, the go-to sequence of Nova bits for sanding and polishing many commercial lapidary materials with a Foredom or Dremel is the 280, 600, 1200, and 3,000 grit diamond polishing bits, followed by the use of a 14,000 grit Nova Point. A Dremel will need a #481 collet to fit these shafts, available for a few dollars at any hardware store selling Dremel accessories. While this sequence will put an acceptable polish on most stones, many hard-to-polish material may require more steps such as additional grit Nova burrs, phenolic burs with diamond paste, or felt burs with your favorite lapidary polish such as tin oxide, or cerium oxide.
