Keeps Cutting After Other Discs Quit
3M Cubitron II Flap Disc 969F powered by 3M Precision-Shaped grain and a tough polyester backing is our highest-performing flap disc for demanding applications like heavy grinding, edge deburring and beveling. It also features a grinding aid that helps it run cool to maintain cutting efficiency on heat-sensitive metals. All of these attributes make 3M Cubitron II Flap Disc 969F a good match for projects that require an equally durable and versatile abrasive disc.
Flap Disc Design
Flap discs are the ideal choice for a wide range of applications on a variety of metals. The abrasive flaps offer a long-lasting supply of fresh abrasives in a load-resistant design. Designed for use with a right-angle grinder, flap discs allow you to breeze through a wide range of applications with less chance of gouging even for less-experienced grinders.
Powered by 3M Precision-Shaped Grain
3M Cubitron II Flap Disc 969F features our proprietary 3M Precision-Shaped Grain a grain design that continually fractures into sharp points that slice cleanly through metal, unlike traditional abrasives which tend to plow through the substrate. The grains fracture evenly and continuously to expose new sharp edges to keep the disc cutting efficiently. The result is that 3M Cubitron II products out-cut and outlast conventional ceramic industrial abrasives.
