3M™ Standard Abrasives™ Buff and Blend Hook and Loop GP Vacuum Disc 831708 is made from tough, resin-reinforced nylon fiber with abrasive grain. It is an ideal choice for general-duty applications as it provides a high cut rate while producing consistent finishes. It blends minor surface imperfections, handling marks and coated abrasives secondary burrs. The center hole discs may be ganged on a shaft and used as a wheel. It resists loading, which means no metal contamination to the work piece. 3M™ Standard Abrasives™ Buff and Blend Hook and Loop GP Vacuum Disc 831708 is made from tough, resin-reinforced nylon fiber with abrasive grain.
