3M 7100202117 Psa Cloth Sanding Disc 36 Grit 7.5 in

Product Description

The 3M 7100202117 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, this disc resists tearing and edge wear under aggressive grinding and sanding loads. The 36-grit aluminum oxide abrasive delivers fast cutting action with extended service life. A resin bond over the abrasive layer protects against heat buildup during prolonged use, keeping the disc cutting efficiently on metal, wood, and composite surfaces.

This disc is suited for metalworking, fabrication, woodworking, and surface preparation tasks where a durable, high-adhesion disc is required. The PSA backing mounts directly to a compatible backup pad or steel platen, allowing quick disc swaps with minimal downtime. Both wet and dry sanding applications are supported, making this disc a versatile choice for fabrication shops, maintenance crews, and trade professionals who run high-volume sanding operations.

Key Features

• Pressure-sensitive adhesive backing adheres firmly to backup pads or steel platens and releases cleanly for fast replacement
• X-weight cloth backing handles aggressive material removal without tearing or edge degradation
• 36-grit aluminum oxide abrasive provides fast stock removal and long abrasive life across a range of surfaces
• Resin bond layer resists heat damage to extend overall disc life
• Suitable for both wet and dry sanding applications

Compatibility

Designed for use with PSA-style backup pads and steel platens accepting a 7.5-inch diameter disc with a 2-inch arbor configuration.

Installation Notes

Mounting and disc changes should be performed with the tool powered off and disconnected from the power source. Press the PSA disc firmly onto a clean, dry backup pad or platen surface to ensure full adhesion before use. Inspect the disc for damage before each use and replace immediately if tears, delamination, or uneven wear are observed. Follow applicable ANSI and OSHA abrasive wheel safety guidelines when operating disc grinders and sanders.
