3M 7100145468 Abrasive Disc Roll 5 Inch 320 Grit Film

Product Description

The 3M 7100145468 is a coated abrasive disc roll in the Cubitron II 775L series, designed for aggressive stock removal on a wide range of substrates. It uses 3M Precision Shaped Grain technology, where triangular ceramic mineral particles are engineered to slice through material rather than plow or gouge the surface. The result is a disc that cuts up to 2 times faster and lasts up to 6 times longer than conventional abrasive discs. The film backing adds tear resistance and helps the disc hold its shape at the edge during use. Each disc measures 5 inches in diameter and is rated at 320 grit for fine finishing and stock removal work.

This disc roll is suited for metalworking, fabrication, and surface preparation applications where consistent cut rate and disc longevity matter. The 320 grit rating makes it appropriate for finishing passes and light stock removal on metals, composites, and other hard substrates. The Stikita attachment system allows fast disc changes without tools, which reduces downtime during production or field work. It is packaged as a roll, making it practical for shops and technicians who go through discs at high volume.

Compatibility

Designed for use with random orbital and right-angle sanders that accept 5-inch Stikita-style attachment discs. Intended for stock removal and finishing applications on metal, composites, and similar hard substrates.

Installation Notes

Installation and disc changes should be performed with the sander powered off and disconnected from its air or electrical supply. Confirm the tool spindle speed rating is compatible with the disc before operation. Inspect the disc for damage before each use and replace immediately if tears or delamination are observed. Follow applicable workplace safety guidelines for abrasive grinding and surface preparation.
