Long-lasting, high-performance and extremely consistent abrasive flap discs featuring 3M Precision-Shaped Grain and a durable polyester backing. Extremely conformable and versatile during use, 769F will generate a finish that is one grade finer than a fibre disc of the same grade. While a fibre disc may initially cut faster, this flap disc can eliminate steps and disc change-outs to help you save time and boost productivity. The polyester backing further enhances durability, and when combined with their conformability it means they hold up to high-pressure applications like beveling, weld grinding and edge deburring extremely well. Additionally, they leave a lasting finish that makes them a great choice for applications like blending and surface prep.
