FLEX GRINDING DISC 3M™ CUBITRON™ II 3M™ Cubitron II flexible grinding discs are both flexible and high-performing, offering an excellent cutting rate with 3M's precision-shaped ceramic grain. They are much more flexible than conventional bonded grinding discs and are available in various diameters and grains for grinding, beveling, or deburring operations. These discs provide superior cutting power and wear out half as fast as our previous reference. With advanced abrasive construction using 3M's precision-shaped ceramic grains, they penetrate and cut metal faster, last longer, and generate much less heat on the workpieces compared to conventional abrasives.
