High Quality Construction
3M™ Cubitron™ II Flap Disc 969F (PDF, 414 Kb) is best suited for metal grinding and finishing thanks to its unique design and fast cutting abrasive material. This disc features a grinding aid, which runs cooler, and helps prevent discoloration on metal surfaces. The semi-flexible, Y-weight, backing gives each flap excellent strength. These attributes make Cubitron™ II Flap Disc 969F a good match for projects that require an equally durable and versatile abrasive disc.
Flap Disc Design
Coated abrasive flap discs are the ideal choice for moderate grinding, blending, beveling, scale removal, and finishing on a variety of metals. The abrasive flaps offer a long lasting supply of fresh abrasives in a load resistant design. Though designed for use with a right-angle grinder (PDF, 5.1 Mb), the flap disc design allows for creative application to fit whatever job you might have.

The Cubitron™ II Advantage
Our proprietary 3M™ Cubitron™ II abrasive products have raised the bar for high-performing abrasives. Our engineers started with 3M™ Ceramic Abrasive Grain and used technology to electrostatically orient each triangular structure on the backing to form sharp peaks and maximize cutting potential. These peaks act like individual cutting tools that slice through metal, and continuously shelf-sharpen as the points break off, ensuring extended high performance in heavy-duty production applications. The grains wear evenly and provide extra-long life and consistency with less grinding pressure. The result is that Cubitron™ II products out-cut and outlast every conventional ceramic industrial abrasive product on the market, maximizing productivity and minimizing belt stress and operator fatigue.
