These brushes have a wide-face construction which is highly effective on both metallic and non-metallic materials. Since the cutting action does not require the use of a compound, the need to clean finished parts is eliminated. The brushes may be used singly or mounted in multiple for a wider face. Certain styles are available with rectangular filaments. Applications: Deburring-Turbine blade dovetails, Dovetail slots on turbine disc/rotors, Powder metal gears and pedestal grinders in robotic cells.
