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 it’s 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. Applications Weld grinding Beveling Edge deburring Blending Finishing Surface preparation Scale removal Weld spatter removal 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.
