Bristle brush rolls are used for deburring, paint prep, cleaning, and polishing. Brush rolls are made of heat stabilized nylon filaments impregnated with abrasive grain, usually aluminum oxide, silicon carbide, CBN, or diamond. Fiber diameter and abrasive grit determine the level of abrasion. Nylon brushes without abrasive grain can be used for cleaning and polishing. Brush rolls have a hook and loop attachment style and are designed to be cut for customized use.
