3M Flap Disc 577F tackles the toughest high-pressure metalworking applications and leaves a blended finish, all in a single step. This 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.

  • 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

PRODUCT FAQ

  1. What is a 3M™ Flap Disc?

    A 3M™ Flap Disc is an abrasive tool for grinding, blending and finishing metal surfaces. It features overlapping layers of abrasive-coated flaps that fan out from a central hub.

  2. What makes the 3M™ Flap Disc 577F different from other flap discs?

    The 3M™ Flap Disc 577F has sharper grains that cut faster than conventional aluminum oxide or ceramic products. Its advanced design also reduces heat generated during use, extending disc life and delivering an exceptional finish.

  3. How do I attach the Quick Change Flap Disc to my angle grinder?

    The Quick Change feature on this flap disc allows you to quickly and easily change the disc without any tools required. Simply twist off your old worn-out disc and snap in the new one until it clicks into place!

  4. How many discs come in each case of the T29 Quick Change,7 inch x5/8 inch-11 version of this product?

    Each case contains five (5) high-quality T29 style discs with a diameter of seven inches and a mounting hole size of five-eighths inches by eleven thread per inch – perfect for heavy-duty grinding applications!

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.
