Spend less time sanding with the fastest-cutting, longest-lasting net abrasives in the world. Introducing 3M Cubitron II Net Abrasives. 3M's biggest advancement in dust-extraction sanding in decades. How much better are they? 3M tested 3M Cubitron II Net Abrasives against the leading competitors. Every grade — every brand — they tested, 3M Cubitron II Net Abrasives outperformed and outlasted them all. The family of 3M Cubitron II Net Discs cuts more than 2X faster and lasts more than twice as long as the Mirka Abranet Ace family of net discs. The unique design on the disc's cutting face is engineered to deliver the best-possible cut without sacrificing dust extraction, 3M technology nobody else has. 3M Cubitron II Net Discs work with standard dust extraction systems including portable dust extractors, central vac systems and sanders with attached bags. 3M Cubitron II Net Discs are available in grades from 80+ to 320+ to handle collision repair jobs from teardown to paint prep faster than any other net discs around. Their long life means fewer stops to change abrasives, while their faster cut rate means you'll spend less time sanding. Prolong the life of your sander's backup pad and maintain consistent attachment with the use of a protection pad or pad saver.
