Featuring a premium self-sharpening zirconia plus grain that lasts up to 30 percent longer than competitors' discs, the BlueFire R884P delivers an aggressive cut to quickly smooth away imperfections on hard carbon steel, wood, fiberglass and other surfaces. The Y-weight polyester waterproof backing can handle even high-pressure alloys, while the semi-open coat is ideal for use on soft metals, including bronze and aluminum.
