Product Description

Advantages of 3M Xtract™ Cubitron™ II Film Disc 775L

  • COVERS A WIDE RANGE OF APPLICATIONS: Choose from grades between 80+ and 400+ to handle applications ranging from finishing to coarse sanding, excelling at stock removal
  • DESIGNED FOR CLEAN SANDING: The 3M Xtract™ proprietary multi-hole pattern provides superior dust extraction to prevent loading, help increase productivity, and provide a cleaner work environment
  • WORKS WELL ON MANY SURFACES: Suitable for use on all metals, aluminum, carbon steel, composites, wood, fiberglass, gelcoat, topcoats, and paint
  • QUICK AND EASY DISC CHANGES: The 3M™ Hookit™ attachment system allows for easy disc changes and helps optimize disc life
  • OPEN COAT CONSTRUCTION: Open coat construction and load-resistant coating prevent clogging to optimize cut throughout the life of the disc
  • REVOLUTIONARY GRAIN DESIGN: 3M Precision-Shaped Grain (PSG) technology cuts quickly and effectively
  • DURABLE FILM BACKING: Film backing offers greater tear resistance and edge retention compared to paper-backed discs

3M Xtract™ Cubitron™ II Disc 775L features a 3M proprietary multi-hole pattern for improved dust extraction in finishing applications. Part of the 3M Xtract™ Series, this disc is designed for optimal dust removal. An innovative multi-hole pattern extracts dust better than 5- or 6-hole products — increasing cut and dramatically increasing disc life. The design does not need to align with the disc pad holes, making switching the discs fast, easy and convenient.

This disc features ceramic 3M Precision-Shaped Grain, a revolutionary advancement in abrasive technology. The triangular shaped ceramic mineral is designed to slice through the substrate, rather than gouging or “plowing” like conventional abrasives, resulting in a disc that cuts up to 2x as fast as conventional abrasives. The film backing delivers outstanding tear resistance, flexibility and a consistent, uniform finish on a variety of substrates.

These discs are ideal for a broad range of applications focused primarily on stock removal, and are effective on a wide variety of substrates, including metals, composites, gelcoat, and whitewood. The film backing offers greater tear resistance than paper discs, for additional durability and edge retention. For best results, pair with 3M Xtract™ Random Orbital Sanders. Open coat construction means the abrasive grains are placed with space between them to help evacuate dust and other sanding debris and avoid clogging the cutting edge of the grains. The load-resistant coating allows the disc to continue cutting even when sanding softwoods, paints, and other materials that would, otherwise, clog the disc and hinder sanding ability. All of this adds up to increased productivity and reduced material consumption. Sandpaper discs cut better and last longer when dust isn’t loading the cutting surface of the abrasives. 3M’s proprietary multi-hole pattern on 3M Xtract™ products removes dust at a higher rate than 5- or 6-hole products. This hole design doesn’t even require alignment of holes with the disc pad, making disc changes quick and simple. For maximum dust extraction, use this disc with a 3M Xtract™ Back-up pad and a random orbital sander with vacuum (both sold separately).
