3M 7000118903 Psa Cloth Sanding Disc 8 in 60 Grit Ao

Product Description

The 3M 7000118903 is a pressure-sensitive adhesive (PSA) cloth sanding disc designed for heavy-duty material removal in industrial and trade applications. Built on an X-weight cloth backing, the disc handles aggressive grinding and sanding without tearing or edge breakdown. The 60-grit aluminum oxide abrasive delivers fast cutting action and extended service life across a broad range of surfaces. A resin bond holds the abrasive grain in place and dissipates heat to protect disc integrity during prolonged use. At 8 inches in diameter, this disc is sized for standard backup pads and steel platens used in metalworking, fabrication, and finishing operations.

This disc is suited for both wet and dry sanding applications, making it versatile across metal fabrication shops, woodworking facilities, and production grinding environments. The PSA backing bonds securely to compatible backup pads or steel platens for stable, vibration-free operation, and releases cleanly for fast disc changes with minimal downtime. It is commonly used by machinists, fabricators, and industrial maintenance technicians working on ferrous and non-ferrous metals, composites, and wood substrates.

Key Features

• Pressure-sensitive adhesive backing bonds to backup pads or steel platens and allows clean, fast removal for quick disc changes
• X-weight cloth backing withstands aggressive sanding loads without tearing or edge wear
• 60-grit aluminum oxide abrasive provides fast stock removal and long abrasive life
• Resin bond protects against heat buildup, extending disc service life
• Suitable for both wet and dry sanding applications
• 8-inch diameter fits standard PSA backup pads used in industrial finishing

Compatibility

Designed for use with backup pads and steel platens that accept 8-inch PSA-style sanding discs in industrial grinding and finishing applications.

Installation Notes

Installation is performed by trade technicians and industrial operators familiar with rotary sanding equipment. Before mounting, ensure the backup pad or platen surface is clean and free of debris to allow full adhesive contact. Press the disc firmly onto the pad, starting from the center and working outward to eliminate air pockets. Power down all equipment before disc removal or replacement.
