3M 7100041214 Psa Cloth Disc 8 Inch 80 Grit Ao

Product Description

The 3M 7100041214 is a pressure-sensitive adhesive (PSA) cloth sanding disc designed for heavy-duty material removal in professional finishing and fabrication environments. Built on an X-weight cloth backing, this disc handles aggressive grinding and sanding without tearing or edge breakdown. The aluminum oxide abrasive cuts fast and maintains performance across a wide range of surfaces. A resin bond system protects the abrasive layer from heat buildup, extending disc service life. At 8 inches in diameter and 80 grit, this disc is suited for stock removal, surface preparation, and intermediate finishing steps on metal, wood, and composite materials.

This disc is intended for use in industrial and trade settings where high-volume sanding is required. The PSA backing adheres directly to a compatible backup pad or steel platen, making disc changes fast and straightforward. It is suitable for both wet and dry sanding applications, giving operators flexibility depending on the workpiece material and finishing requirement. Typical users include metal fabricators, woodworkers, and surface preparation technicians working with stationary or portable disc sanders.

Key Features

• Pressure-sensitive adhesive backing bonds securely to backup pads or steel platens and releases cleanly for quick disc changes
• X-weight cloth backing resists tearing and edge wear under aggressive sanding loads
• Aluminum oxide abrasive delivers fast cut rates and long service life across metal, wood, and composite surfaces
• Resin bond system dissipates heat to protect the abrasive layer and extend disc life
• Compatible with both wet and dry sanding applications

Compatibility

Designed for use with backup pads or steel platens that accept 8-inch PSA-style sanding discs on stationary and portable disc sanders.

Installation Notes

Ensure the backup pad or platen surface is clean and free of debris before applying the disc to achieve full PSA adhesion. Press the disc firmly and evenly onto the pad to eliminate air pockets before operation. Power down and disconnect the sander from its power source before mounting or removing any abrasive disc. Follow applicable workplace safety standards for eye, hearing, and respiratory protection when operating abrasive equipment.
