3m™ flap disc 577f giant 4-1/2" x 5/8-11 t27 alumina zirconia 60 grit 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
- Applications are blending, deburring, edge beveling, finishing, polishing, right angle grinding metal fabrication
