Product Details
The 3M™ Flap Disc 577F Giant is a 7" diameter by 7/8" arbor size T29 style disc featuring alumina zirconia abrasive with 36 grit. Designed for tough grinding applications where final finish is important, the disc's overlapping layers of abrasive-coated, fiber-reinforced flaps continually wear away with use to expose fresh abrasive mineral, providing a fast, consistent cut while cushioning the workpiece for a blended finish. These flap discs typically deliver a finish one grade finer than the disc's grit, reducing finishing steps. The disc includes a grinding aid to reduce grinding temperatures, making it suitable for heat-sensitive alloys such as stainless steel, nickel alloys, and titanium. Intended for use on a right angle grinder, the Giant size features wider flaps than standard flaps, packed with 25% more abrasive material for a more aggressive cut and longer life. The three-dimensional layered flap construction allows the disc to follow curves and contours easily, delivering less gouging and improved operator comfort. This flap disc is a one-step alternative to bonded wheels and fiber discs, effectively grinding and finishing weld seams, deburring, rust removal, edge grinding, blending, and polishing in metal fabrication. The product meets applicable industry standards for durability and performance. Warranty information is provided under normal use conditions, with specific terms available from the manufacturer.
