With the 3M Cubitron II Flap Disc 969F, 3M enhances its flap disc line with a more robust version that excels in higher pressure applications and critical surfaces (such as burrs) due to its optimized design, offering longer service life. Features of this flap disc include a higher packing density of the abrasive flaps combined with a durable flap 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 remain at all times. This results in a continuously clean finish on the material. The outcome is a fast, cool grind and extended lifespan of the abrasive.
