3M Flap Disc Alumina Zirconia, 4 1/2 in, 40 Grit, Coarse, 7/8 hole

Description

Ideal for tough grinding applications where final finish is important, the overlapping layers of the flaps on 3M(TM) 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.
Flap discs are used on a right angle grinder. Giant size flap discs have the same diameter as standard flap discs but wider flaps. The wider flaps create extra-thick layers and are packed with 25% more abrasive material than on standard flap discs, for more aggressive cut and longer life.
