5" Zirconia Resin Fiber Discs — Premium Metal Grinding

USA1 Abrasives 5" Zirconia Resin Fiber Discs deliver superior performance on stainless steel, hardened metals, and other tough materials where aluminum oxide wears out prematurely. Zirconia alumina's self-sharpening properties maintain an aggressive cut rate throughout the disc's life, significantly reducing cost per part in high-volume metalworking applications. 7/8" arbor hole. Sold in packs of 25 discs.
