Cone Shape Sintered Diamond Burs

These cone-shaped sintered burs have precisely graded diamonds embedded in metal matrix through the entire head to carve consistently over a long life. USAGE These flat head cone/tapered cylinder, rounded cone, pointed cone, and inverted cone shape SUVA Shards are the highest-performing diamond carving burs for lapidary, jewelling, engraving, and sculpting in gemstones, opals, glass, metal, ceramic, porcelain and hard wood. Sintered carving burs are used in a rotary tool such as a Dremel or Foredom flexible shaft in a high speed handpiece or micro motor, or in a fixed-point lathe or pendant drill. They are the best tool available for carving and grinding stone in Lapidary and jewellery making. Use larger coarse-grit sintered burrs for pre-forming, shaping, and grinding, and work your way up to finer grits and smaller heads for carving small details or precise gemstone cuttings.
