3M 577F Flap Disc – Medium – 80 – Type 27
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. 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.
