3M 7100145372 Abrasive Film Disc 240 Grit 6 Inch

Product Description

The 3M 7100145372 is a coated abrasive film disc engineered for aggressive stock removal on a wide range of substrates. Built on the Cubitron II 775L platform, it uses 3M Precision Shaped Grain technology — triangular ceramic mineral particles that slice through material rather than plowing or gouging the way conventional abrasives do. The result is a disc rated to cut up to 2 times faster and last up to 6 times longer than standard abrasive discs. At 6 inches in diameter and 240 grit, it targets fine stock removal and surface finishing tasks in metalworking, fabrication, and similar trade applications.

This disc is suited for professional grinding and finishing operations where consistent cut rate and disc longevity matter. The 240 grit rating positions it for finishing passes and light stock removal after rougher operations. The Stikit pressure-sensitive adhesive backing allows fast, tool-free disc changes on compatible random orbital and disc sanders, reducing downtime during production runs. The film backing adds tear resistance and helps the disc hold its shape and edge through demanding use cycles.

Key Features

• 3M Precision Shaped Ceramic Grain cuts up to 2 times faster than conventional abrasive discs
• Disc life rated up to 6 times longer than conventional abrasives, reducing change frequency
• Film backing provides greater tear resistance and maintains edge integrity under load
• Stikit pressure-sensitive adhesive attachment enables fast, tool-free disc swaps
• 240 grit for finishing and light stock removal across a variety of substrate types
• 6-inch diameter fits standard random orbital and disc sander pads with Stikit compatibility

Compatibility

Designed for use with Stikit-compatible random orbital sanders and disc sander backup pads accepting 6-inch pressure-sensitive adhesive discs.

Installation Notes

Mounting and removal require no tools — press the disc firmly onto a clean, dry Stikit backup pad and peel to remove. Ensure the backup pad surface is free of debris or adhesive buildup before attaching a new disc, as contamination reduces adhesion and can cause disc separation during use. Always operate the sander at the speed rating appropriate for the disc size, and wear appropriate eye and respiratory protection when grinding or sanding.
