3M 7100145428 Cubitron Ii 775L 6 Inch 240 Grit Abrasive Disc

Product Description

The 3M 7100145428 is a coated abrasive disc roll featuring Cubitron II 775L technology with 3M Precision Shaped Ceramic Grain. The triangular ceramic mineral is engineered to slice through material rather than gouge or plow like conventional abrasive grains. This results in a disc that cuts up to 2 times faster and lasts up to 6 times longer than standard abrasives. The film backing provides superior tear resistance and edge retention compared to paper-backed discs. At 6 inches in diameter and 240 grit, this disc is suited for fine stock removal and surface preparation tasks. Installation and disc changes use the Stikita pressure-sensitive adhesive attachment system, allowing fast swaps without tools.

This disc roll is designed for grinding and finishing applications on a wide variety of substrates, with a primary focus on stock removal. It is well-suited for metal fabrication, automotive bodywork, woodworking, and composite surface preparation in both shop and field environments. The 240 grit rating targets finish sanding and light material removal stages where surface quality and cut rate both matter. Trade professionals in fabrication, metalworking, and finishing trades rely on this format for consistent results across production and repair workflows.

Compatibility

Designed for use with 6 inch random orbital sanders and disc grinders equipped with a hook-and-loop or PSA backup pad compatible with Stikita-style adhesive-backed discs.

Installation Notes

Disc changes should be made with the tool powered off and unplugged or air supply disconnected. Ensure the backup pad surface is clean and free of debris before applying the Stikita adhesive-backed disc to promote full contact and secure adhesion. Discard discs that show tearing, loading, or uneven wear to maintain consistent cut quality and operator safety. Follow applicable ANSI and OSHA abrasive product safety guidelines for maximum operating speeds and personal protective equipment requirements.
