3M 7100106742 Hook and Loop Film Disc 80 Grit 3 Inch

Product Description

The 3M 7100106742 is a 3-inch coated abrasive film disc designed for high-speed stock removal on a wide range of substrates. It uses 3M Precision Shaped Ceramic Grain, a triangular mineral that slices into the workpiece rather than plowing across it like conventional abrasives. This geometry allows the disc to cut up to 2 times faster and last up to 6 times longer than standard abrasive discs. The hook-and-loop attachment system allows fast disc swaps without tools. Film backing adds tear resistance and helps the disc hold its edge throughout its service life. Metalworkers, fabricators, and finishing technicians working in light manufacturing and production environments are the primary users.

This disc is suited for stock removal applications across metal, composites, and other hard substrates where cut rate and disc longevity are priorities. The 80-grit rating positions it for aggressive material removal and surface leveling rather than fine finishing. It attaches to any compatible 3-inch hook-and-loop backup pad, making it a straightforward drop-in for existing angle grinder and random orbital setups. Sold individually, it is a practical choice for production shops running high disc volume.

Key Features

• 3M Precision Shaped Ceramic Grain slices substrate for faster cut rates versus conventional abrasive minerals
• Cuts up to 2 times faster than conventional abrasives
• Disc life up to 6 times longer than conventional abrasive discs
• Film backing provides greater tear resistance and edge retention compared to paper backing
• Hook-and-loop attachment for tool-free disc changes
• Suited for a wide range of substrates with focus on stock removal

Compatibility

Designed for use with 3-inch hook-and-loop backup pads on angle grinders and random orbital sanders configured for hook-and-loop discs.

Installation Notes

This disc is installed and replaced by metalworkers, fabricators, and production finishing technicians. Before changing discs, power down the tool and allow it to come to a complete stop. Ensure the backup pad surface is clean and free of debris before seating the disc to maintain proper hook-and-loop engagement. Always verify the tool RPM rating is compatible with the disc before operation.
