3M flap disc 769F is a high performance abrasive disc built for versatility and value. Powered by 3M precision shaped grain, it lasts longer and cuts faster than conventional aluminum oxide and alumina zirconia flap discs and its priced for affordability and everyday use. This unbeatable combination of performance and value can increase productivity while also lowering your abrasive spend. Value priced Performance with built-in versatility. 3M flap disc 769F is a long lasting, versatile abrasive disc that includes all the advantages you expect from a flap disc, including conformability and ease of use with a lower risk of gouging. Featuring 3M precision shaped grain and a durable polyester backing, 3M flap disc 769F lasts long and holds up strong to high pressure applications like beveling, weld grinding and edge deburring. Plus, it leaves a finish that makes it a great choice for applications like blending and surface prep. Powered by 3M precision shaped grain. The 3M flap disc 769F features a blend of 3M precision shaped grain a proprietary 3M grain design that continually fractures into sharp points that slice cleanly through metal, unlike traditional abrasives which tend to plow through the substrate. This fracturing helps 3M flap disc 769F last long and maintain a high cut rate over the life of the disc. Tech Tip: in many cases, 3M flap disc 769F will allow you to grind and finish in one step, without changing abrasives. This is because, under normal conditions, 769F will generate a finish that is one grade finer than a fiber disc of the same grade. While a fiber disc will cut faster, this flap disc can eliminate steps and disc change outs to help save you time.
