3M 7000118885 Psa Cloth Sanding Disc 20 Inch 60 Grit

Product Description

The 3M 7000118885 is a PSA cloth sanding disc designed for heavy-duty material removal across a wide range of industrial and trade applications. Built on an X-weight cloth backing, it holds up under aggressive pressure without tearing or edge breakdown. The 20-inch disc uses aluminum oxide abrasive at 60 grit for fast stock removal and extended service life. A pressure-sensitive adhesive backing mounts directly to a compatible backup pad or steel platen, making disc swaps fast and clean. A resin bond system protects the abrasive layer from heat buildup, helping the disc last longer under sustained use.

This disc is suited for large-surface grinding, blending, and finishing operations where a 20-inch format is required. It supports both wet and dry sanding conditions, giving it flexibility across metal fabrication, woodworking, and surface prep environments. Minimum order quantity is 10 discs per unit. Typically installed and operated by machinists, fabricators, or surface finishing technicians working with large rotary or stationary disc equipment.

Key Features

• Pressure-sensitive adhesive backing adheres securely to backup pads or steel platens and removes cleanly for fast replacement
• X-weight cloth backing resists tearing and edge wear under aggressive sanding loads
• Aluminum oxide abrasive delivers fast cutting action and long service life across multiple surface types
• Resin bond construction provides heat resistance to extend disc life during sustained use
• Compatible with both wet and dry sanding applications

Compatibility

Designed for use with backup pads or steel platens that accept 20-inch PSA-mount sanding discs in wet or dry disc sanding equipment.

Installation Notes

Installation is performed by trained fabrication or surface finishing technicians. Ensure the backup pad or steel platen surface is clean and free of debris before applying the PSA disc to achieve full adhesion. Disengage and lock out equipment power before mounting or removing the disc. Do not exceed the rated maximum operating speed of 7,500 meters per second surface speed.
