Spend less time sanding with the fastest-cutting, longest-lasting net abrasive sheets in the world. Introducing 3M Cubitron II Net Abrasive Sheet Rolls. 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. In fact, 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 abrasive design on these sheets' face is designed to deliver the best-possible cut without sacrificing dust capture. It's a 3M technology nobody else has. 3M Cubitron II Net Sheet Rolls work with standard dust extraction systems including portable dust extractors, central vacuum systems and sanders with attached bags. 3M Cubitron II Net Sheet Rolls are available in three widths – 2.75 inches (70mm) , 3 inches (80 mm), and 4.5 inches (115mm) – in grades from 80+ to 320+. They handle collision repair jobs from teardown to paint prep faster than any other sheet rolls around. Their long life means fewer stops to change abrasives, while their faster cut rate means you'll spend less time sanding each job.
