BUSCH 446AU CARBIDE BEARING CUTTER


Equip your jewellery bench with the Busch 446AU Carbide Bearing Cutters, engineered for precision shaping, seat‑opening and internal detail work in hard‑to‑reach areas. Built from fine‑grain tungsten carbide, these cutters offer exceptional durability and cutting power, especially on tougher metals such as platinum, white gold and titanium.

The 70° bearing cutter head is specifically designed for consistent, controlled cuts when refining pavé settings, enlarging starter holes, or smoothing internal walls— helping you achieve sharp results with less polishing.

Ideal for professional jewellers, advanced hobbyists and students alike, the Busch 446AU series offers high‑performance, reliable tooling that adapts to the challenges of intricate work and demanding alloys.
