2.76″ x 32.81′ | Grit 180+ 3M Cubitron II Net Discs combine patented 3M Cubitron II precision-shaped grains with a net backing pattern to deliver performance nobody matches. See less dust. 3M Cubitron II Net Abrasives help dust extractors achieve their best possible performance. The 3M Hookit attachment makes installing a new sheet quick and saves a partially-used disc easily. The patented triangular-shaped mineral grains on these net sheets slice through substrates, rather than gouging or “plowing” like conventional abrasive grains. This helps the sheet run cooler, cut faster, and last longer.
