3M 7100055945 Psa Cloth Sanding Disc 60 Grit 1 Inch

Product Description

The 3M 7100055945 is a pressure-sensitive adhesive (PSA) cloth sanding disc designed for heavy-duty material removal in industrial and trade finishing applications. Built on an X-weight cloth backing, it uses an aluminum oxide abrasive bonded with a resin system that resists heat buildup and extends disc life. At 1 inch in diameter and rated for up to 20,000 RPM, this disc mounts quickly to a backup pad or steel platen and releases cleanly for fast changeover. It is suitable for both wet and dry sanding operations, making it versatile across metal, wood, and composite surfaces.

This disc is used in precision sanding, deburring, and surface conditioning tasks where a small-diameter, high-speed abrasive is required. The 60-grit aluminum oxide construction delivers aggressive stock removal while maintaining consistent cut rate over the life of the disc. It is well suited for use with rotary tools, inline grinders, and small-platen finishing equipment common in fabrication shops, maintenance facilities, and production environments. A licensed machinist, metal fabricator, or finishing technician would typically install and operate this disc.

Key Features

• PSA backing adheres firmly to backup pads or steel platens and releases cleanly for quick disc replacement
• X-weight cloth backing handles aggressive sanding without tearing or edge breakdown
• Aluminum oxide abrasive delivers fast cutting and long service life across a wide range of surfaces
• Resin bond resists heat damage, preserving abrasive performance over extended use
• Rated to 20,000 RPM for compatibility with high-speed rotary tools
• Suitable for both wet and dry sanding applications

Compatibility

Designed as an OEM-style PSA sanding disc for use with backup pads or steel platens accepting 1-inch diameter adhesive-backed abrasive discs.

Installation Notes

Ensure the tool is powered off and disconnected from its power source before mounting or removing the disc. Verify the backup pad or steel platen is clean and free of debris before applying the PSA disc to ensure full adhesion. Do not exceed the rated 20,000 RPM maximum speed marked on the disc or tool. Wet sanding applications require confirmation that the tool and all connected equipment are rated for wet use.
