The Anatomy of a Versatile, Medium-Duty Disc
3M Cubitron II Flap Disc 967A ? powered by 3M Precision-Shaped Grain and a poly-cotton backing ? is well-suited for medium-duty applications including weld, scale and oxide removal, light deburring, surface preparation and blending. Along with the poly-cotton backing, this disc also features an incorporated grinding aid to help it run cool and cut efficiently on heat-sensitive metals. This all adds up to a disc that strikes a balance of fast cut and long life.
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 967A features our proprietary 3M Precision-Shaped ? 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 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.
