  • Hand doing sanding application using 3M Cubitron II Film Disc

    The 3M™ Cubitron™ II Sanding Disc is a revolutionary advancement in abrasive technology featuring triangular shaped ceramic mineral. 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. Now available in grades 240+, 320+, and 400+.

    • Cuts faster compared to conventional abrasives by increasing throughput with faster sanding and more parts per disc.
    • Lasts longer than conventional abrasives due to lower costs with long disc life and fewer disc changes.
    • Provides consistent finish compared to conventional abrasives with minimal rework due to consistent finish quality.
