About 3M Flap Disc 566A, T29 Giant, 4-1/2" Diameter, 40
Product Description 3M Flap Disc 566A 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. From the Manufacturer The 3M™ Flap Disc 566A Type 29 Giant 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. TYPE 29 is angled for aggressive stock removal and fast cutting on both flat and curved surfaces. 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. 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. Flap discs are used on a right angle grinder. For attachment, 4-1/2 inch flap discs require a flap disc adapter nut. Max RPM is 13,300. 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.
