7" Zirconia Resin Fiber Discs
7" Zirconia Resin Fiber Discs — Premium Heavy-Duty Metal Grinding
USA1 Abrasives 7" Zirconia Resin Fiber Discs combine maximum disc coverage with zirconia alumina's superior cutting performance for the most demanding industrial grinding applications. The 7" diameter removes more material per pass while zirconia's self-sharpening properties maintain an aggressive cut rate throughout the disc's life on stainless steel, hardened metals, and other tough materials. 7/8" arbor hole. Sold in packs of 25 discs.
