Constructed with 25% more material than our standard flap discs, our Standard Abrasives(TM) Zirconia AP HD Flap Disc offers extra-long life for a range of metal fabrication tasks. It features extra-sharp alumina zirconia mineral on durable overlapping poly-cotton flaps for continuous sharp cut, and leaves a smooth finish. Because it is mounted on a firm phenolic plate, there is a cushion effect when blending.
