3M 7100145467 Abrasive Disc Roll 6 Inch 320 Grit

Product Description

The 3M 7100145467 is a coated abrasive disc roll in the Cubitron II 775L series, engineered for high-speed stock removal on a wide range of substrates. These 6-inch diameter discs use 3M Precision Shaped Grain technology, a ceramic mineral formed into a triangular shape that slices through material rather than plowing or gouging like conventional abrasives. The result is a disc that cuts significantly faster and outlasts standard abrasive products. The film backing adds tear resistance and helps maintain edge integrity during aggressive grinding operations. This product is sold as a roll, making it suited for shops with high disc turnover.

These discs are designed for stock removal applications across metal fabrication, woodworking, composites, and similar trades. The Stikiti attachment system allows for fast disc changes without tools, reducing downtime on the shop floor or job site. At 320 grit, the discs are well suited for finishing passes and fine stock removal where surface quality matters alongside cut rate. They are commonly used by fabricators, welders, body technicians, and production grinding operations.

Key Features

• Precision Shaped Ceramic Grain technology cuts aggressively and extends disc life compared to conventional abrasives
• Film backing provides greater tear resistance and edge retention under load
• Stikiti attachment system enables fast, tool-free disc changes
• 320 grit rating targets fine stock removal and finishing-stage grinding
• 6-inch diameter fits standard random orbital and disc sanders with compatible backing pads
• Sold as a roll for high-volume use environments

Compatibility

Designed for use with 3M Stikiti-compatible backing pads that accept 6-inch film-backed abrasive discs. Verify backing pad compatibility before installation.

Installation Notes

Installation is performed by pressing the disc firmly onto a clean, compatible Stikiti backing pad — ensure the pad surface is free of debris before attaching. Power down and disconnect the tool from its power source before changing discs. Inspect the backing pad for wear or damage prior to each disc change, as a deteriorated pad can cause uneven contact and reduce disc performance. Follow all applicable workplace safety guidelines for abrasive tool operation.
