PRODUCT FAQ

What is the 3M™ Flap Disc 577F made of?

The flap disc is made with alumina zirconia abrasive grain, which gives it excellent performance and durability.
How does the 60 grit rating affect its performance?

The 60 grit rating means that this flap disc is suitable for medium to high-pressure grinding and finishing applications on steel, stainless steel, non-ferrous metals, and alloys.
What type of backing material does this flap disc have?

The backing material used for this flap disc is a sturdy polyester cloth that provides strong support during operation while still offering flexibility.
Can I use this flap disk on an angle grinder?

Yes! It has a T27 shape and fits securely onto an angle grinder's arbor.
How many pieces are included in one package or case?

. One case of the 3M™ Flap Disc contains five pieces each having dimensions of 7 inches x .875 inches (diameter x arbor hole size).

3M™ Flap Disc 577F

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.

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.

Flap discs are three-dimensional grinding discs with overlapping layers of abrasive-coated, fiber-reinforced flaps that fan out from a central hub. These flaps continually wear away with use to expose fresh mineral for a fast, consistent cut. The one-step alternative to bonded wheels and fiber discs, flap discs grind and finish in a single step, making them a time and cost-saving solution in many typical applications. Under normal conditions, flap discs will generate a finish that is one grade finer than the finish of a fibre disc of the same grade. And, because their overlapping construction allows more abrasive material to be loaded onto the cutting surface, they far outlast typical discs. Flap discs have the flexibility to easily follow curves and contours while delivering less gouging and enhancing operator comfort. They are ideal for a wide range of applications, including weld grinding, deburring, rust removal, edge grinding, and weld seam blending.
