Use the fastest-cutting, longest-lasting net discs in the world. 3M Cubitron II Net Discs combine patented 3M Cubitron II precision-shaped grains with an optimized abrasive pattern to deliver performance nobody matches. See less dust. 3M Cubitron II Net Abrasives help dust extractors achieve their best-possible performance. Youll get dust capture that cant be beat whether youre using a self-generating-vacuum sander, a central vacuum system or a portable dust extractor. Like other 3M Cubitron II abrasives, the patented triangular-shaped mineral grains on these net discs slice through substrates, rather than gouging or plowing like conventional abrasive grains. This helps the disc run cooler, cut faster, and last longer. 3M Cubitron II Net Discs are available in grades from 80+ to 320+ and in the most-popular disc sizes, making them compatible with existing dust-extraction sanders. The 3M Hookit attachment makes installing a new disc quick and saving a partially-used disc easy. 3M Cubitron II Net Abrasives, paired with the Total Automotive Sanding System, capture the most dust nobody’s system works better.
