These black bristle polishing brushes from Grobet USA are built for professional jewelers and metalsmiths who demand consistent, reliable performance at the polishing motor. Featuring genuine Chungking bristles mounted in seasoned hardwood hubs, these brushes deliver superior polishing action and extended service life compared to standard bristle brushes.
The hardwood hubs are oil-treated to resist splitting under repeated use, and bristle tufts are staple-set directly into the hub to stay firmly anchored until fully worn down — no premature shedding or loosening during operation. The 1/4" arbor hole fits the tapered spindles found on standard polishing motors, making these a straightforward drop-in addition to any bench setup.
