3M Standard Abrasives Zirconia HP Type 27 HD Flap Disc 645869 7 in x 7/8 in 60 5 per case

Constructed with 25% more material than our standard flap discs, our Standard Abrasives(TM) Zirconia HP HD Flap Disc offers extra-long life for rapid, high pressure grinding operations. It features extra-sharp alumina zirconia mineral on hard-wearing polyester flaps. The flaps wear away with use to reveal fresh, sharp mineral for beveling, deburring, and edge chamfering. Because it is mounted on a firm phenolic plate, there is a cushion effect when blending.
