The 70° Bearing Cutter Bur is designed for creating accurate bearing seats before stone setting. Its angled profile forms clean, controlled cuts in prongs and settings, giving stones a secure, level seat with minimal risk of over-cutting. Ideal for faceted stones and precision jewelry work where consistent bearing depth is critical.
Manufactured by Busch to exacting standards. Standard 3/32" shank fits all common flex shaft handpieces, pendant drills, and micromotor systems.
