3M™ Cubitron™ II Hookit™ Paper Disc 732U features 3M Precision Shaped Ceramic Grain, a revolutionary advancement in abrasive technology.

  • Cuts up to 2x as fast as conventional abrasives
  • Lasts up to 4x as long as conventional abrasives
  • Ideal for a wide variety of substrates and applications focused primarily on stock removal

Product Description: 3M Sanding Discs

These sanding discs are versatile and effective on a wide range of substrates, including metals, composites, gelcoat, and whitewood. They are ideal for applications focused on stock removal and are backed with C-weight paper, making them suitable for sanding tasks where edge retention is not a primary requirement. For optimal results, use with 3M™ Elite Random Orbital Sanders.

A complete line of hook-and-loop style 3M™ Hookit™ discs is also available for workspaces where adhesive-backed discs may become contaminated by dust or dirt. Hookit™ discs are often used in applications where a 3M™ Stikit™ disc may be too aggressive, as they tend to leave finer finishes than adhesive-backed discs. These sanding discs conveniently attach to a hook-and-loop backup disc pad (sold separately), can be removed cleanly and easily, and can be re-used again and again for the extent of the abrasive life.
