3M 769F Flap Disc, Conical P80 T29, 115 mm x 22 mm

If you need a versatile, conformable flap disc that delivers performance and durability, use the 3M™ 769F Flap Disc. Our discs, featuring 3M™ Precision Grain Technology, have been proven to outperform traditional aluminum zirconia flap discs. This abrasive continuously fractures into sharp points and cuts cleanly through metal, unlike traditional abrasives, which tend to plow through the substrate. This fracturing, combined with the breakdown of individual flakes to expose renewed mineral, helps provide a consistently high cutting rate throughout the life of the disc. The polyester backing further increases its durability, and this, combined with its adaptability, means that it can withstand high-pressure applications such as beveling, weld grinding, and edge deburring. In addition, it leaves a finish that makes it an excellent choice for applications such as homogenization and surface preparation. In many cases, the 3M™ 769F flap disc will allow you to roughen and polish in a single step, without changing abrasives. This is because, under normal conditions, the 769F will produce a finish that is one grade finer than the finish of a fiber disc of the same grit. A fiber disc will cut faster, but this flap disc eliminates steps and disc changes, saving time and increasing productivity. A fiber disc will cut faster, but this flap disc eliminates the need for steps and disc changes, saving time and increasing productivity. They are ideal for use on carbon steel, stainless steel, and other heat-sensitive alloys.
