With the 3M Cubitron II Flap Disc 969F, 3M adds a more robust version to its flap disc line, which excels in terms of longer service life under higher pressure and on critical surfaces (such as edges) due to its optimized design. Features of this flap disc include a higher density of the grinding flaps combined with a durable backing. The precision-formed ceramic grain from 3M significantly contributes to the performance of this disc. The grain tips of the triangular segments break during the grinding process, ensuring that sharp cutting edges are always maintained. As a result, the surface of the material is continuously processed cleanly. The outcome is a fast, cool grind and an extended lifespan of the abrasive.
