About Cleaning & Finishing Bristle Discs

Molded flexible bristles on these discs provide more surface contact than wire brushes and can be used for cleaning, deburring, finishing, and removing coatings, rust, and adhesives. The bristles contain durable abrasives that offer reduced buildup and improved safety compared to wire filament, which are sharp and may break off. Choose coarser discs for heavier material removal and finer discs for lighter material removal.

These discs have connections for attachment to angle grinders, which provide more maneuverability into corners and edges than a drill or die grinder. The straight bristles are flexible and can handle most general-purpose applications.
