BUSCH 414AU CARBIDE HART BUR
Upgrade your jewellery‑bench performance with the 414AU Carbide Hart Burs. These high‑grade tungsten‑carbide burs feature the « Hart» profile — crafted for detailed shaping, internal contouring, and precision stock removal. Their carbide construction means they hold up incredibly well against tougher alloys like platinum, white gold, titanium and high‑nickel metals.
Designed for refined bench work, these burs excel in tasks such as cleaning up cast flash, shaping seat‑walls, finishing internal surfaces and achieving crisp transitions. Suitable for flex‑shafts, micromotors and high‑speed rotary tools, they deliver consistent, reliable results for students, hobbyists and professional jewellers alike.
