Description

Designed for use on the tapered spindles of polishing motors, these black bristle brushes feature genuine Chungking bristles mounted into seasoned hardwood hubs with 1/4" arbor holes. Chungking bristles deliver longer service life and superior polishing action piece after piece, making these brushes a reliable choice for professional jewelers and metalsmiths who demand consistent finishing results.

The hardwood hubs are oil-treated to resist splitting and ensure long-lasting durability through extended use. Bristle tufts are staple-set directly into the hub, keeping them securely fastened until fully worn—eliminating premature bristle loss during polishing operations.

Features

  • Genuine Chungking bristles for longer life and superior polishing action
  • Seasoned hardwood hubs, oil-treated to prevent splitting
  • Staple-set bristle tufts remain firmly anchored until completely worn
  • 3 rows of converging bristles for effective, consistent coverage
  • 1/4" arbor hole fits tapered spindles of standard polishing motors
  • Sold in a pack of 3
