Product Description: 3M Sanding Discs

3M Sanding Discs are versatile and effective on a wide range of substrates, including metals, composites, gelcoat, and whitewood. These discs are ideal for applications focused on stock removal and are available in a complete line of hook-and-loop style 3M Hookit discs.

The C-weight paper backing is well suited for sanding applications where edge retention is not a primary requirement. For best results, pair with 3M Elite Random Orbital Sanders.

3M Hookit discs are perfect for workspaces where adhesive-backed discs may become contaminated by dust or dirt. They leave finer finishes than adhesive-backed discs and are often used in applications where a 3M Stikit disc may be too aggressive.

  • Hookit sanding discs attach conveniently to a hook-and-loop backup disc pad (sold separately).
  • They can be removed cleanly and easily and can be re-used again and again for the extent of the abrasive life.
