A fiber abrasive brush can deburr surfaces on multiple levels. The company’s unique manufacturing process allows for the specification of long trim brushes with infinitely variable filament density and trim length. The brush pictured is used to deburr the surface of a “green” powder metal part. The part has three ½-in. protrusions requiring that the brush extend below the protrusions to deburr the target surface. The abrasive filaments are composed of heat-stabilized nylon, which has been coextruded with an abrasive grit. The filaments are anchored in a durable resin backing. Abtex Corp.,
