3M 7100046322 Abrasive Disc 120 Grit 5 Inch Hook Loop

Product Description

The 3M 7100046322 is a 5-inch coated abrasive disc built for aggressive stock removal on a wide range of surfaces. It uses 3M Precision Shaped Grain technology, a ceramic mineral formed into a triangular shape that slices through material rather than gouging or plowing like conventional abrasive grits. The result is a disc rated to cut up to 2x faster and last up to 6x longer than standard abrasive discs. The film backing adds tear resistance and helps the disc hold its edge geometry through demanding applications. Attachment is hook and loop for fast pad changes without tools.

This disc is designed for stock removal work across metal, composites, and similar hard substrates in industrial, fabrication, and finishing environments. The 120 grit rating positions it for moderate-to-fine material removal, blending, and surface prep prior to finishing or coating. The hook and loop mount makes it compatible with random orbital and disc sanders equipped with a hook-face backup pad. It is suited for professional use in metal fabrication shops, auto body, aerospace, and general manufacturing.

• Film backing provides greater tear resistance and edge retention under load
• Hook and loop attachment allows tool-free disc changes on compatible backup pads
• 5 inch diameter, 120 grit for moderate-to-fine stock removal and surface prep
• Suitable for a wide variety of substrates focused on aggressive material removal

Compatibility

Designed for use with 5-inch hook-face backup pads on random orbital sanders and disc grinders. No specific model compatibility data was provided in the input.

Installation Notes

Mounting and removal of hook and loop discs should be done with the sander powered off and unplugged or the air supply disconnected. Align the disc squarely to the backup pad before applying pressure to seat the hook and loop interface. Inspect the backup pad face for worn hooks or debris before installing a new disc, as a degraded pad reduces holding force and can cause disc separation during use. Follow applicable shop safety protocols and wear appropriate PPE including eye and respiratory protection during grinding operations.
