3M 7100145474 Abrasive Film Disc 400 Grit 6 Inch

Product Description

The 3M 7100145474 is a coated abrasive film disc engineered for aggressive stock removal on a wide range of substrates. It uses 3M Precision Shaped Ceramic Grain, a triangular mineral geometry that slices through material rather than plowing through it the way conventional abrasives do. The result is a disc rated to cut up to 2x faster and last up to 6x longer than standard abrasive discs. At 6 inches in diameter and 400 grit, it fits applications requiring fine-to-medium finishing after initial material removal. The Stikita pressure-sensitive adhesive backing allows fast, tool-free disc changes.

This disc suits metal fabrication, woodworking, composites, and similar stock-removal tasks where consistent cut rate and disc longevity matter. The film backing provides greater tear resistance and edge retention compared to paper-backed alternatives, making it a reliable choice for both high-cycle production environments and smaller-volume finishing work. It is sold individually and sized for standard 6-inch random-orbit and disc sanders used by fabricators, finishing technicians, and skilled tradespeople.

Key Features

• 3M Precision Shaped Ceramic Grain geometry slices substrate rather than gouging, extending disc life
• Cuts up to 2x faster than conventional abrasive discs
• Lasts up to 6x longer than conventional abrasives, reducing disc change frequency
• Film backing delivers superior tear resistance and edge retention versus paper backing
• Stikita PSA attachment system allows quick, tool-free disc swaps
• 400 grit suited for refined stock removal and surface prep across multiple substrate types

Compatibility

Designed as an OEM-style replacement disc for 6-inch random-orbit and disc sanders equipped with a Stikita or standard PSA-compatible platen.

Installation Notes

Installation is performed by finishing technicians and fabricators without special tools. Before mounting, ensure the sander platen is clean and free of adhesive residue from the previous disc to ensure full contact and secure adhesion. Press the disc firmly onto the PSA platen before powering the tool. Always wear appropriate eye and respiratory protection when operating abrasive discs.
