3M 7100064178 Sanding Disc 180 Grit 6 Inch Hook Loop

Product Description

The 3M 7100064178 is a coated abrasive sanding disc built for aggressive stock removal on a wide range of substrates. It uses 3M Precision Shaped Grain, a triangular ceramic mineral engineered to slice through material rather than gouge or plow, the way conventional abrasive grains tend to work. The result is a disc that cuts up to 2 times faster and lasts up to 6 times longer than standard abrasives. The film backing adds tear resistance and helps maintain edge integrity throughout the life of the disc. A hook and loop attachment system allows fast disc swaps without tools.

This disc is suited for metalworking, woodworking, and composite surface preparation where rapid stock removal is the primary goal. The 6-inch diameter and 180 grit rating make it appropriate for finishing passes or intermediate sanding on flat and contoured surfaces. The multi-hole pattern on the disc face is designed to work with compatible random orbital sanders that have dust extraction ports, keeping the work surface cleaner and extending disc life by reducing loading.

Key Features

• 3M Precision Shaped Grain ceramic mineral slices material for faster cut rates
• Cuts up to 2 times faster than conventional abrasive discs
• Lasts up to 6 times longer than conventional abrasive discs
• Film backing provides greater tear resistance and edge retention over paper backing
• Hook and loop attachment allows tool-free disc changes
• Precision multi-hole pattern supports dust extraction for cleaner sanding

Compatibility

Designed for use with 6-inch hook and loop random orbital sanders equipped with compatible dust extraction port patterns.

Installation Notes

Attach the disc to a compatible hook and loop sanding pad by aligning the hole pattern with the sander ports before pressing firmly into place. Ensure the sander is powered off and unplugged before changing discs. Inspect the hook and loop pad for wear before mounting a new disc, as a degraded pad reduces holding force and can cause the disc to release during use. Operate within the sander manufacturer's recommended RPM rating for the disc diameter.
