Product Details
The 3M™ Flap Disc 577F Giant measures 7" in diameter with a 5/8-11 T27 arbor and features 60 grit alumina zirconia abrasive for tough grinding applications where a final finish is important. Its overlapping layers of abrasive-coated, fiber-reinforced flaps continuously wear away to expose fresh abrasive mineral, providing a fast, consistent cut and a blended finish that is typically one grade finer than the disc grit. The disc includes a grinding aid to reduce grinding temperatures, suitable for heat-sensitive alloys such as stainless steel, nickel alloys, and titanium. Designed for use on a right angle grinder, the Giant size flap disc has the same diameter as a standard flap disc but with wider flaps packed with 25% more abrasive material, offering a more aggressive cut and longer life. This three-dimensional grinding disc serves as a one-step alternative to bonded wheels and fiber discs by grinding and finishing simultaneously, enhancing efficiency and reducing finishing steps. The flexible flap design conforms easily to curves and contours with less gouging and improved operator comfort, making it ideal for blending, deburring, edge beveling, finishing, polishing, weld grinding, rust removal, edge grinding, and weld seam blending in metal fabrication. The product dimensions are 7" diameter and 5/8-11 T27 arbor size, and it carries applicable industry certifications and compliance standards. Warranty terms are provided to ensure product reliability under normal use conditions.
