3M 7000118911 Psa Cloth Sanding Disc 348D 80 Grit 3/4 Inch

Product Description

The 3M 7000118911 is a pressure-sensitive adhesive (PSA) cloth sanding disc in the 348D series, designed for heavy-duty material removal in industrial and trade finishing applications. The disc measures 3/4 inch in diameter, carries an 80-grit aluminum oxide abrasive, and is rated to 20,000 RPM. It mounts to a backup pad or steel platen via a high-strength PSA backing that holds firmly during use and releases cleanly for fast disc changes. A resin bond protects the abrasive layer from heat buildup, extending working life. The disc supports both wet and dry sanding operations.

This disc is suited for metalworking, woodworking, and composite surface preparation tasks where a small-diameter, high-speed abrasive is needed. Typical applications include deburring, surface conditioning, weld blending, and finish sanding in tight or contoured areas. The 80-grit cut rate makes it appropriate for aggressive stock removal before progressing to finer grits. It is commonly used by fabricators, millwrights, and finish carpenters on production lines or bench grinding setups.

Key Features

• PSA backing adheres to backup pads or steel platens and releases cleanly for quick disc changes
• X-weight cloth backing resists tearing and edge wear under aggressive stock-removal loads
• Aluminum oxide abrasive delivers fast cutting and long service life across a range of materials
• Resin bond construction reduces heat damage and extends disc life
• Rated for both wet and dry sanding applications
• High-speed rating of 20,000 RPM supports production-pace tooling

Compatibility

Designed for use with backup pads and steel platens that accept 3/4 inch PSA-mount sanding discs at speeds up to 20,000 RPM.

Installation Notes

Installation is performed by trade professionals or equipment operators familiar with abrasive tooling. Before mounting or removing a disc, power down the tool and confirm it has come to a complete stop. Verify the backup pad or platen is clean and free of adhesive residue before applying a new disc to ensure full PSA contact. Always confirm the tool's rated operating speed does not exceed the disc's 20,000 RPM maximum before use.
