Busch Starlight Carbide Polishers deliver a super high polish on platinum and gold without removing material. As burnishing burs, they compact the surface to create brilliant, mirror-like finishes ideal for highlighting elevated edges, curved shanks, and recessed or difficult-to-access areas. The high-polish effect is especially striking when contrasted with a matte or textured finish, adding dimension and visual interest to fine jewelry pieces. Best results are achieved at speeds between 25,000–35,000 RPM, making these polishers best suited for use with a micromotor capable of reaching those speeds.
