Plated Diamond Bur Sets

Electroplated diamond burs provide value-focused, reliable cutting action for shaping and carving lapidary minerals and gemstones, glass, opals, porcelain, metals, or other hard materials Use these plated diamond burs to grind your initial shape 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. You can further extend the life of your diamond burs with the optional use of 412 Slick Lube diamond tool lubricant.
