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.
