3M 7100145456 Cubitron Ii 775L 6 Inch 400 Grit Film Disc Roll

Product Description

The 3M 7100145456 is a coated abrasive disc roll featuring Cubitron II 775L film-backed discs with 3M Precision Shaped Ceramic Grain technology. Each disc measures 6 inches in diameter and carries a 400 grit rating. The triangular ceramic mineral is engineered to slice through material rather than gouge or plow like conventional abrasives, delivering faster stock removal with less heat buildup. The film backing provides greater tear resistance and edge retention compared to paper-backed alternatives. This roll format is used by metalworkers, fabricators, and finishing technicians who require consistent, high-volume abrasive performance across demanding production environments.

The 7100145456 disc roll is suited for stock removal applications on a wide variety of substrates including metals, composites, and painted surfaces. The 400 grit rating positions these discs for intermediate-to-fine finishing stages where controlled material removal and surface refinement are both required. The Stikita attachment system allows for fast disc changes on compatible random orbital and disc sanders, reducing downtime during production runs. These discs are appropriate for both shop and field use wherever a reliable, consistent cut is needed at the 6 inch diameter.

Installation Notes

Installation of abrasive discs should be performed by trained metalworking or finishing technicians. Ensure the sander or grinder is powered off and disconnected from any power source before changing discs. Align the disc firmly and evenly onto the Stikita backing pad before operating the tool. Inspect each disc for damage before use and do not exceed the rated operating speed of the tool or disc.
