3M 7100145429 Cubitron Ii 775L 5 Inch 240 Grit Abrasive Disc

Product Description

The 3M 7100145429 is a coated abrasive disc roll featuring the Cubitron II 775L construction with Precision Shaped Ceramic Grain technology. The triangular ceramic mineral is engineered to slice through material rather than plow or gouge like conventional abrasives, delivering faster stock removal and longer service life. Each disc measures 5 inches in diameter and carries a 240 grit rating, making it well suited for fine stock removal and finishing passes. The film backing provides superior tear resistance and edge retention compared to paper-backed alternatives. Licensed tradespeople and fabricators working in metal fabrication, surface prep, and grinding applications will find this disc a direct performance upgrade over standard aluminum oxide or zirconia products.

This disc roll is designed primarily for stock removal applications across a wide variety of substrates including ferrous and non-ferrous metals, painted surfaces, and composites. The Stikita attachment system allows for fast disc changes without tools, reducing downtime on the job. The 240 grit designation targets controlled material removal and intermediate finishing stages. This roll format is suited for shop environments where high disc consumption justifies bulk packaging, including automotive body shops, metal fabrication facilities, and maintenance operations.

Key Features

• Precision Shaped Ceramic Grain slices substrate rather than gouging, cutting up to 2x faster than conventional abrasives
• Service life up to 6x longer than conventional abrasive discs under comparable conditions
• Film backing delivers greater tear resistance and edge retention versus paper backing
• Stikita attachment system enables fast, tool-free disc changes
• 5 inch diameter at 240 grit targets stock removal and intermediate finishing
• Roll format supports high-volume shop use

Compatibility

Designed for use with 5 inch random orbital and disc sanders equipped with a Stikita-compatible or hook-and-loop backup pad. Confirm backup pad attachment compatibility before use.

Installation Notes

Installation and disc changes should be performed with the sander powered off and unplugged or battery removed. Ensure the backup pad surface is clean and free of debris before attaching each disc to maintain proper adhesion. Inspect the disc for tears or damage before each use. Worn or damaged discs should be replaced immediately to prevent workpiece damage or operator injury.
