3M 7100168272 Psa Cloth Disc 8 Inch 50 Grit Ao

Product Description

The 3M 7100168272 is a pressure-sensitive adhesive (PSA) cloth sanding disc designed for heavy-duty material removal on a wide range of surfaces. Built on an X-weight cloth backing, this disc handles aggressive grinding and finishing applications without tearing or edge breakdown. The aluminum oxide abrasive delivers fast cutting action and extended service life. A resin bond system protects the disc from heat buildup, keeping the abrasive effective through longer run times. At 8 inches in diameter with a 50 grit rating and a maximum speed of 6000 RPM, it is suited for high-volume sanding operations in metalworking, woodworking, and fabrication environments.

This disc is intended for use on stationary or handheld disc sanders equipped with a compatible backup pad or steel platen. The PSA backing allows the disc to be pressed onto the pad surface and removed cleanly when worn, minimizing downtime during disc changes. It is rated for both wet and dry sanding applications, giving operators flexibility depending on the material and finish requirement. Typical users include metal fabricators, woodworkers, and industrial maintenance technicians working in production or job-shop settings.

Key Features

• Pressure-sensitive adhesive backing adheres firmly to backup pads or steel platens and releases cleanly for fast disc changes
• X-weight cloth backing resists tearing and edge wear under aggressive sanding pressure
• Aluminum oxide abrasive cuts fast and maintains performance across metal, wood, and composite surfaces
• Resin bond construction dissipates heat to extend disc life
• Rated for both wet and dry sanding applications
• Maximum speed of 6000 RPM supports use on standard disc sanding equipment

Compatibility

Designed for use with disc sanders and grinders equipped with a PSA-compatible backup pad or flat steel platen accepting an 8 inch diameter disc.

Installation Notes

Installation is performed by pressing the PSA backing firmly and evenly onto a clean, dry backup pad or steel platen, ensuring full contact to prevent disc slippage during operation. Power down and de-energize the sanding machine before mounting or removing any disc. Do not exceed the rated maximum speed of 6000 RPM. Inspect the disc and backing pad for damage before each use and replace any disc showing signs of tearing, delamination, or worn abrasive.
