Description

Engineered for demanding polishing applications, these black bristle brushes feature genuine Chungking bristles mounted into oil-treated seasoned hardwood hubs. Chungking bristles are prized for their superior polishing action and extended service life, delivering consistent results piece after piece. Each hub is drilled with a 1/4" arbor hole sized for use on the tapered spindles of standard polishing motors. Bristle tufts are staple-set directly into the hub, keeping them securely fastened until fully worn down — eliminating premature shedding during use. The oil-treated hardwood hubs resist splitting under the stress of regular motor-driven polishing, ensuring long-lasting, reliable service.

Features

  • Genuine Chungking bristles for superior polishing action and longer service life
  • 3 converging rows of bristles for effective surface contact and coverage
  • Bristle tufts are staple-set into hubs to stay securely fastened until completely worn
  • Seasoned hardwood hubs are oil-treated to prevent splitting
  • 1/4" arbor hole fits tapered spindles of standard polishing motors
  • Sold in packs of 3
