3M 7100106764 Abrasive Disc 120 Grit 3 Inch Hook and Loop

Product Description

The 3M 7100106764 is a 3-inch coated abrasive disc built for aggressive stock removal on a wide range of substrates. It uses precision-shaped ceramic grain formed into a triangular profile that slices through material rather than plowing or gouging the way conventional abrasives do. The result is a disc rated to cut up to 2 times faster and last up to 6 times longer than standard abrasive discs. The film backing adds tear resistance and holds the disc edge intact through demanding grinding and finishing passes. A hook-and-loop attachment system lets the operator swap discs quickly without tools.

This disc is suited for metal fabrication, woodworking, and composite surface prep where fast material removal is the priority. At 120 grit, it sits in the fine-to-medium range, making it effective for blending, surface leveling, and prep work before finishing. It is used by metalworkers, fabricators, and finishing technicians on random orbital and disc sanders equipped with a compatible hook-and-loop backup pad.

Key Features

• Precision-shaped ceramic grain cuts up to 2 times faster than conventional abrasives
• Ceramic mineral geometry extends disc life up to 6 times longer than standard abrasives
• Film backing provides superior tear resistance and maintains edge integrity
• Hook-and-loop attachment enables fast, tool-free disc changes
• 120 grit rating suited for stock removal, blending, and surface prep
• 3-inch diameter fits standard random orbital sanders with matching backup pads

Compatibility

Designed for use with 3-inch hook-and-loop backup pads on random orbital sanders and disc grinders. Confirm the sander accepts a 3-inch hook-and-loop disc before installation.

Installation Notes

Installation is performed by finishing technicians and fabricators. Power down and disconnect the sander from its power source before attaching or removing the disc. Press the disc firmly onto the hook-and-loop backup pad to ensure full contact and prevent slipping during operation. Inspect the disc for tears or worn grain before each use and replace as needed.
