These sintered diamond bur sets provide reliable cutting action for shaping and carving lapidary minerals and gemstones, glass, opals, porcelain, metals, or other hard materials Use these diamond sintered burs to grind your initial shaping before sanding with Diamond Pacific Nova Sanding Points or Diamond Rubber sanding burs, and finishing with felt burs charged with your favorite lapidary polish or hardwood polishing burs loaded with diamond paste. When choosing valuable sintered burs, be sure to maintain and re-shape the cutting heads with a Diamond Re-Shaping Block or sharpening stones, using water and very light pressure to expose new sharpened diamond layers. You can further extend the life of your diamond burs with the optional use of 412 Slick Lube diamond tool lubricant. Specifications All burs are constructed with a shaped, fully sintered diamond head mounted to a 44.5mm HP 3/32" (2.35 mm) shank for use in your Foredom flex-shaft handpieces, Dremel, or other electric rotary micro motors. Sizes are stated in approximate head width at the widest point x head height, and size may vary slightly within an acceptable tolerance for lapidary work.
