3M 7100145365 Abrasive Film Disc 320 Grit 5 Inch

Product Description

The 3M 7100145365 is a coated abrasive film disc engineered for aggressive stock removal on a wide range of substrates. Built around 3M Precision Shaped Ceramic Grain technology, the triangular ceramic mineral slices through material rather than gouging or plowing, delivering faster cut rates and extended disc life compared to conventional abrasives. At 320 grit and 5 inches in diameter, this disc suits finishing and intermediate stock-removal steps in metalworking, woodworking, and composite surface preparation. The Stikita hook-and-loop style attachment system allows fast disc changes without tools. Licensed tradespeople and skilled fabricators working with random orbital sanders will find this disc well-suited to production and repair environments.

This disc is designed primarily for stock removal applications across a broad range of materials including metals, composites, and wood substrates. The film backing resists tearing and maintains edge integrity during aggressive use, making it appropriate for both flat and contoured surfaces. It is sold as an individual disc and is suited to shop environments where consistent cut rate and disc longevity are priorities.

Key Features

• 3M Precision Shaped Ceramic Grain technology delivers up to 2x faster cut rate than conventional abrasives
• Ceramic grain geometry slices rather than gouges, extending disc life up to 6x compared to conventional abrasives
• Film backing provides superior tear resistance and consistent edge retention during use
• Stikita attachment system enables quick, tool-free disc changes on compatible random orbital sanders
• Suited for a wide variety of substrates with a primary focus on stock removal applications

Compatibility

Designed for use with random orbital sanders that accept 5-inch diameter Stikita hook-and-loop style abrasive discs.

Installation Notes

This disc is installed and removed by hand on compatible random orbital sanders using the Stikita attachment system. Ensure the sander is powered off and unplugged before changing discs. Verify the backing pad is clean and free of debris to ensure secure disc adhesion. Follow all applicable workshop safety practices and wear appropriate PPE including eye protection and respiratory protection when sanding.
