3M 7100145454 Cubitron Ii 775L 6 in 400 Grit Abrasive Disc Roll

Product Description

The 3M 7100145454 is a coated abrasive disc roll featuring Cubitron II 775L technology with Precision Shaped Ceramic Grain. The triangular ceramic mineral is engineered to slice through material rather than gouge or plow like conventional abrasive grains, delivering faster stock removal and extended disc life. At 400 grit and 6 inches in diameter, these film-backed discs are suited for finishing and light stock removal on a wide range of substrates. The Stiklt attachment system allows for quick disc changes during production work, reducing downtime. Sold as a roll, the package weighs 4.35 pounds.

These discs are used in metal fabrication, woodworking, composites, and general industrial surface preparation where consistent cut rate and disc longevity are priorities. The 400-grit rating targets finish-stage work or intermediate stock removal where surface quality matters alongside throughput. The film backing resists tearing and holds its edge under aggressive use, making these discs reliable in both high-cycle production environments and intermittent service work.

Key Features

• Precision Shaped Ceramic Grain cuts up to 2x faster than conventional abrasive minerals
• Disc life up to 6x longer than conventional abrasives, reducing changeover frequency
• Film backing provides greater tear resistance and improved edge retention
• Stiklt pressure-sensitive attachment system enables fast, tool-free disc changes
• 6 inch diameter at 400 grit suited for finishing and intermediate stock removal
• Compatible with a wide variety of substrates including metals, wood, and composites

Compatibility

Designed for use with 6 inch random orbital and disc sanders equipped with a Hookit or pressure-sensitive adhesive (PSA) backup pad compatible with the Stiklt attachment system.

Installation Notes

Disc installation should be performed with the sander powered off and disconnected from the power source. Align the disc squarely to the backup pad before applying pressure to seat the adhesive attachment fully. Inspect the backup pad for wear or damage before mounting a new disc, as an uneven pad surface reduces abrasive performance and can cause premature disc failure. Follow tool manufacturer guidelines for maximum RPM ratings to ensure safe operation.
