3M 7100191052 Sanding Disc 3 Inch P80 Grit Ao 200 Pack

Product Description

The 3M 7100191052 is a 3-inch coated abrasive sanding disc designed for hook-and-loop backup pads. Built on a C-weight paper backing, it carries an aluminum oxide grain in an open-coat, load-resistant configuration at P80 grit. A proprietary multi-hole pattern distributes dust extraction ports across the disc surface, evacuating debris more effectively than standard 5- or 6-hole patterns. The scalloped edge helps minimize material buildup at the perimeter. This disc is suited for finish prep, material removal, and surface leveling tasks performed by trade professionals in woodworking, flooring, cabinet, and light fabrication applications.

The 7100191052 is intended for dry sanding applications where dust management is critical. The open-coat construction resists loading when working softer woods, painted surfaces, or MDF. Hook-and-loop attachment allows fast disc changes without tools, making it practical for production environments where disc rotation is frequent. The 200-disc minimum sell quantity makes it appropriate for shop stock or job-site replenishment orders.

Key Features

• Proprietary multi-hole pattern provides superior dust extraction compared to 5- or 6-hole disc designs
• Open-coat, load-resistant finish coating resists clogging and extends disc service life
• Aluminum oxide abrasive grain cuts faster and outlasts traditional garnet abrasives
• C-weight paper backing delivers firm support for aggressive material removal at P80 grit
• Scalloped edge profile reduces perimeter buildup during extended use
• Hook-and-loop attachment enables tool-free disc changes and disc reuse

Compatibility

Designed for use with 3-inch hook-and-loop backup pads on random orbital and orbital sanders. No specific model compatibility data was provided; verify pad diameter and attachment type before ordering.

Installation Notes

Installed by pressing the disc firmly onto a compatible hook-and-loop backup pad until full surface contact is achieved. Ensure the sander is powered off and unplugged before changing discs. Inspect the backup pad for worn hook material before attaching a new disc, as a degraded pad reduces holding force and can cause disc separation during use. Discs should be stored flat and away from moisture to maintain backing integrity.
