5 in. X 7/8 in. Grit 60,  ENDURO-FLEX by Walter Surface

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.
