3M 7100046320 Abrasive Disc Roll 6 Inch 120 Grit Cubitron Ii

Product Description

The 3M 7100046320 is a coated abrasive disc roll in the Cubitron II 775L series, engineered for high-speed stock removal on metal, composites, and other industrial substrates. The disc uses 3M Precision Shaped Grain technology, a triangular ceramic mineral that slices through material rather than plowing or gouging like conventional abrasives. The result is a disc that cuts up to two times faster and lasts up to six times longer than standard abrasive discs. At 6 inches in diameter and 120 grit, it is suited for aggressive material removal while maintaining consistent surface finish. The film backing resists tearing and holds its edge under sustained load. This product is used primarily by metalworkers, fabricators, and finishing technicians in production and repair environments.

The 7100046320 disc roll is designed for stock removal applications across a wide range of substrates, including steel, stainless steel, and non-ferrous metals. The Stik-It attachment system allows for fast disc changes without tools, reducing downtime during production runs. The 120 grit rating makes it appropriate for intermediate stock removal and surface blending where both speed and finish quality matter. It is commonly used in fabrication shops, aerospace component finishing, and general metalworking operations. The roll format supports high-volume usage, making it practical for production environments where disc turnover is frequent.

Key Features

• 3M Precision Shaped Ceramic Grain technology cuts up to 2x faster than conventional abrasives
• Ceramic mineral geometry slices substrate rather than gouging, extending disc life up to 6x
• Film backing provides greater tear resistance and sustained edge retention
• Stik-It attachment system enables tool-free disc changes for faster workflow
• 6 inch diameter at 120 grit targets aggressive stock removal with consistent cut rate
• Roll format supports high-volume production use

Compatibility

Designed for use with 5-inch and 6-inch random orbital sanders and grinders equipped with a Stik-It or hook-and-loop backup pad compatible with 6-inch film-backed discs.

Installation Notes

Installation is performed by metalworkers and finishing technicians using compatible random orbital or disc sanders. Ensure the backup pad is clean, flat, and free of debris before attaching the disc to maintain full contact and prevent premature wear. Shut down and disconnect the tool from power before changing discs. Do not exceed the maximum RPM rating of the tool or backup pad when using abrasive discs.
