3M Flap Disc 566A, T27, YF-Weight, Zirconia Alumina, 7" Diameter, 5/8"-11 Thread, 60 Grit (Pack of 5)

Product Description 3M(TM) flap disc. For aggressive stock removal on a variety of welds. Coatings and other metal fabrication applications. The overlapping coated abrasive cloth flaps on flap discs provide several layers of abrasives, making the disc very durable 7-inches diameter. Grade: 60. Thread size: 5/8"-11. From the Manufacturer The 3M™ Flap Disc 566A Type 27 Quick Change Disc provides a versatile one-disc system for metal fabrication applications where more durability is needed for medium-weight grinding, small weld removal, finishing, and surface preparation. Run on a right angle grinder, this disc is a one-step alternative to bonded wheels and fiber discs—it runs fast enough for stock removal but provides cushioning with the flaps for a smooth finish. The 566A flap disc features self-fracturing alumina zirconia abrasive with a superior cut-rate to aluminum oxide, and versatile performance on many metal types. The 566A flap disc is made with strong yet flexible Y-weight polyester-cotton backing that is well-suited for handling sharp edges and medium to high pressure applications, making this disc a great choice for the majority of grinding and finishing jobs. It is resin-coated for heat resistance. Type 27 is designed for flat surfaces or outside edges, and produces a smooth finish. Under normal conditions, flap discs will generate a finish that is one grade finer than the finish of a fiber disc of the same grade. Each quick change disc comes packaged with a disposable attachment hub and has a 5/8-11 threaded center hole for attachment to a right angle grinder. Max RPM is 8,600.Flap discs are three-dimensional grinding discs with overlapping layers or flaps that fan out from a central hub. These abrasive-coated, polyester-cotton flaps continually wear away with use to expose fresh mineral for a fast, consistent cut. And, because their overlapping construction allows more abrasive material to be loaded onto the cutting surface, they far outlast typical discs. Flap discs are ideal for a wide range of applications, including grinding of small welds (with grades less than 80), deburring, rust removal, edge grinding, and weld seam blending. Alumina zirconia (sometimes called AZ or zirconia alumina) fractures frequently to continually produce fresh sharp points and delivers a faster cut-rate than aluminum oxide. A man-made mineral, it was developed for heavy stock removal and high pressure grinding. For more than a century, 3M has applied innovation and technology to improving our customers’ lives and supporting their business goals. Today the company, from its headquarters in St. Paul, Minnesota, serves industrial and commercial customers and consumers in nearly 200 countries. Abrasive Systems products, including a complete line of coated abrasives, microfinishing and microreplicated abrasives, and hardware accessories, provide the finishing touch for almost any surface modification application. The 3M brand, across thousands of products, represents consistency, superior quality, and value.
