HEAVY-DUTY ZIRCONIA CUTTING: These Zirconia Resin Fiber Sanding and Grinding Discs deliver aggressive cutting power for weld and rust removal, deburring, blending, and surface prep on steel, stainless, aluminum, and other ferrous and non-ferrous metals, plus fiberglass and wood. 4-1/2" x 7/8" ANGLE GRINDER FIT: These 4.5" x 7/8" resin fiber discs fit most right-angle grinders with a compatible backing pad — sized for fabrication, automotive, and metalworking shops.
