3M 7100145374 Abrasive Film Disc 240 Grit 5 Inch

Product Description

The 3M 7100145374 is a coated abrasive film disc engineered for high-efficiency stock removal on a wide range of substrates. Built on the Cubitron II 775L platform, it uses 3M Precision Shaped Grain technology, where triangular ceramic mineral particles are oriented to slice cleanly through material rather than plowing or gouging the way conventional abrasive grains do. The result is a disc that cuts significantly faster and outlasts standard abrasive discs by a measurable margin. At 5 inches in diameter and 240 grit, this disc is well suited for finishing and fine stock removal work. The Stikit pressure-sensitive adhesive backing makes disc changes quick without tools.

This disc is designed for use in metal fabrication, woodworking, and general manufacturing environments where consistent cut rate and disc longevity reduce downtime and consumable cost. The 240 grit rating targets fine surface preparation, light blending, and finishing passes rather than aggressive material removal. The film backing provides greater tear resistance and edge retention compared to paper-backed alternatives, making it suitable for contoured surfaces and precision finishing applications where disc integrity matters. Typically installed and used by machinists, fabricators, and finishing technicians.

Key Features

• 3M Precision Shaped Ceramic Grain technology for faster, cleaner cuts compared to conventional abrasives
• 240 grit rating suited for fine stock removal, surface prep, and finishing passes
• Film backing delivers superior tear resistance and edge retention over paper-backed discs
• Stikit pressure-sensitive adhesive attachment allows fast, tool-free disc changes
• 5 inch diameter fits standard random orbital and disc sanders with Stikit-compatible platens
• Triangular grain geometry slices material rather than plowing, reducing heat and loading

Compatibility

Designed for use with 5 inch Stikit-compatible backup pads and random orbital sanders accepting pressure-sensitive adhesive discs.

Installation Notes

Ensure the backup pad surface is clean and free of debris before attaching the disc to achieve proper adhesion. Power down the sander completely before swapping discs. Align the disc flat against the pad and press firmly from center outward to seat the adhesive. Follow applicable workplace safety guidelines for personal protective equipment when operating abrasive tools.
