Nova Points
Diamond Pacific Nova Points offer a convenient way to quickly sand and polish gemstone and opal carvings with your Foredom or Dremel.
Nova Points solve many gemstone carving challenges by offering the speed, high performance, and no mess of Diamond Pacific's legendary proprietary Nova resin-bond diamond formulas in 2 sizes of 2 Nova tips shapes for use on your carvings during the sanding and polishing processes. They are designed to avoid headaches while sanding those hard-to-reach areas to remove the coarse scratches from your latest lapidary masterpiece.
Construction
Diamond Pacific Nova carving points are a resin-bond diamond compound bonded to a mandrel shaft for use in lapidary rotary tools such as a Foredom or Dremel. Pictures show the reference shape, but Nova burs are slightly flexible and will wear away with use and abuse. Diamond Pacific Nova burs MUST be used with a lubricant like water or silicone extender fluid.
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.
Available Shapes and Sizes
All sizes are approximate on new Diamond Pacific Nova Points and can vary slightly during construction. Diamond Pacific Nova tips for Dremel and Foredom tools have a mandrel size of 3/32 inch which fits most Foredom and Dremel power rotary tools used in gemstone carving.
