Brush Research Manufacturing Co. Inc. says its Nampower abrasive nylon brushes contain ceramic and silicon-carbide filaments to enhance burr-removal rates and impart finer surface finishes in one operation. The abrasive filaments conform to part contours, wiping and filing across part edges and surfaces. The brushes are available in two styles: dot for general-purpose deburring and surface finishing, and turbine for medium and heavy deburring. Both styles can be used with the company's toolholder, which flows coolant from the brush's center.
