Alumina zirconia mineral with a grinding aid provides more cutting power than aluminum oxide across all metal types Flaps combine grinding and blending into one step for time savings Heavyweight polyester-backed flaps provide longer life on high-pressure applications such as sharp-edge work and beveling Quick change disc simplifies disc changes 3M™ Flap Disc 577F tackles the toughest high-pressure metalworking applications and leaves a blended finish, all in a single step. Our abrasive flap disc features fast-cutting alumina zirconia mineral on durable polyester-backed flaps for extra cutting power, and long life on heavy duty applications such as weld removal, sharp-edge work, and beveling. Detail Comparison Close-Up with standard flap disc Ideal for tough grinding applications where final finish is important, the overlapping layers of the flaps on 3M™ Flap Disc 577F continually wear away with use to expose fresh abrasive mineral for a fast, consistent cut, while the cushioning of the flaps creates a blended finish. Flap discs typically generate a finish one grade finer than the disc is graded, reducing finishing steps. A grinding aid reduces grinding temperatures for processes involving heat-sensitive alloys such as stainless steel, nickel alloys, and titanium.
