Ideal for blending, finishing and surface preparation. Provides an even, sharp, clean cut rate and consistent performance at a great value for everyday, general purpose use on metal. When an aggressive cut rate and smooth finish are a must, metal fabricators turn to a resin fiber disc (RFD). Faced with the challenge of working on everything from pressure vessels to roller coasters, professionals need a solution they can count on. Helps optimize grinding time on a wide variety of applications. With premium grain mixes that aggressively remove metal and a superior design that locks the grain in, RFDs are designed to deliver serious grinding solutions. Advanced grain formulas designed to maximize cut rate on metals. Superior design minimizes loading, glazing and grain stripping. Heavy-duty vulcanized fiber backing holds up to the toughest jobs. Quick change hub option reduces down time and eliminates interference from adapter rings.
