3M showed its Cubitron II 775L Film and 732U paper sanding discs at the AWFS Fair 2015. The expanded grade range is now available in 80+ to 220+ grit. When 3M introduced Cubitron II two years ago, it described it as "a revolutionary advancement in abrasive technology featuring triangular shaped ceramic mineral."

Rather than grinding the abrasive material, it is cultured into uniformly pointed grains. As the triangular shaped grain wears, it continually fractures to form sharp points that slice through the substrate, wear evenly and provide extra-long life and consistency, says 3M.Cutting faster, increases throughput with faster sanding and more parts can be completed before the disc is discarded. Lasting longer, it reduces labor and consumables costs. It also provides a more consistent finish to the wood and panel surfaces, with minimal rework due to this consistent finish quality.

Cubitron II Belts were introduced two years ago, in cloth or polyester backing, in widths up to 67 inches. The belts ahve an anti-static coating to reduce loading
and increase belt life; and reduce belt change frequency. A closed coat construction extends the abrasive's life. go.3M.com/FZ
