3M 7100145434 Abrasive Disc Roll 6 Inch 320 Grit Film

Product Description

The 3M 7100145434 is a coated abrasive disc roll in the Cubitron II 775L series, designed for aggressive stock removal on a wide range of substrates. Each disc measures 6 inches in diameter and carries a 320 grit rating, backed by a film layer that resists tearing and maintains edge integrity through demanding finish work. The abrasive mineral is 3M Precision Shaped Ceramic Grain, a triangular-profile ceramic that slices through material rather than plowing across it. The result is a disc that cuts faster and outlasts conventional abrasive discs by a significant margin. The Stikita pressure-sensitive attachment system allows fast disc swaps without tools. This roll format is suited for shops and technicians who cycle through discs at high volume.

The 775L disc roll is used in metalworking, fabrication, and surface finishing applications where stock removal speed and disc longevity are priorities. The 6-inch diameter and 320 grit make it well suited for intermediate finishing passes on metal, composites, and painted surfaces. The film backing holds up under heat and lateral stress better than paper-backed alternatives, making it a reliable choice for orbital and random-orbit sanders in production environments. Trades that commonly use this disc include metal fabricators, auto body technicians, and industrial finishing crews.

Key Features

• 3M Precision Shaped Ceramic Grain slices substrate rather than gouging, delivering faster cut rates
• Cuts up to 2 times faster than conventional abrasive discs
• Lasts up to 6 times longer than conventional abrasives, reducing disc change frequency
• Film backing provides greater tear resistance and edge retention versus paper backing
• Stikita pressure-sensitive attachment allows quick, tool-free disc changes
• 320 grit rating suited for intermediate stock removal and blending passes

Compatibility

Designed for use with 6-inch random-orbit and orbital sanders equipped with a hook-and-loop or Stikita-compatible backup pad. Compatible with a wide variety of substrates including ferrous metals, non-ferrous metals, composites, and coated surfaces.

Installation Notes

A licensed or trained abrasive tool operator should verify that the backup pad diameter and pad type match the 6-inch Stikita disc before mounting. Power down and disconnect the sander from its power source before changing discs. Inspect the disc surface for damage or contamination before each use, and discard any disc showing tears, delamination, or clogging. Follow all applicable shop safety protocols including respiratory protection when grinding or finishing metal or composite substrates.
