3M 7100046326 Cubitron Ii 5 Inch 120 Grit Hookit Film Disc

Product Description

The 3M 7100046326 is a coated abrasive disc designed for aggressive stock removal on a wide range of substrates. Built on the Cubitron II 775L platform, it uses 3M Precision Shaped Grain technology, which features a triangular ceramic mineral that slices through material rather than plowing or grinding like conventional abrasives. The result is a disc that cuts up to 2 times faster and lasts up to 6 times longer than standard abrasive discs. The film backing provides greater tear resistance and edge retention compared to paper-backed alternatives. At 5 inches in diameter with a 120-grit rating, this disc is well suited for general metal fabrication, weld blending, and surface preparation work.

This disc is intended for use with hook-and-loop backup pads on random orbital sanders and die grinders in industrial, fabrication, and finishing environments. It is equally at home in automotive body shops, metal fabrication facilities, and maintenance operations where fast, consistent stock removal is the priority. The hook-and-loop attachment system allows for rapid disc changes without tools, reducing downtime during production runs. It performs on steel, stainless steel, aluminum, and other metals as well as painted or coated surfaces requiring material removal.

Compatibility

Designed for use with 5-inch hook-and-loop backup pads on random orbital sanders, die grinders, and right-angle sanders that accept 5-inch discs.

Installation Notes

Attachment and removal is handled by the built-in hook-and-loop system — no adhesives or tools required. Ensure the backup pad surface is clean and free of debris before attaching the disc to maintain proper contact and prevent premature release. Always operate within the maximum RPM rating of both the tool and the disc. Wear appropriate personal protective equipment including eye protection and respiratory protection when grinding or sanding.
