WALTER Enduro Flap Disc, Enduro Flex, 4-1/2 in Dia Disc, 5/8 in-11 Center Hole, 40 Grit, Coarse, Zirconia Alumina Abrasive, Type 27S Disc, Plastic Backing, 13300 rpm Max

The ENDURO-FLEX one step finishing discs not only meet but surpass the challenges that the metal fabricating and finishing industry faces on a daily basis. With the new ultra sharp and refined zirconium grain, the ENDURO-FLEX finishing disc will stay sharper for a longer period of time while removing more material faster. In addition, a special top coat continuously cools and lubricates the disc for smooth, vibration free grinding and sanding from start to finish. Moreover, there is no need to discard the disc when the flap overhang is worn down to the backing because the ENDURO-FLEX disc can be restored to like-new performance by reducing the diameter of the Eco-Trim™ backing.
