3M 7000118906 Psa Cloth Sanding Disc 6 Inch 40 Grit

Product Description

The 3M 7000118906 is a PSA cloth sanding disc designed for heavy-duty material removal in industrial and trade finishing applications. The disc uses a pressure-sensitive adhesive backing that bonds securely to a backup pad or steel platen, allowing fast mounting and clean removal when swapping discs. At 6 inches in diameter with a 40-grit aluminum oxide abrasive, it delivers aggressive stock removal on metal, wood, and composite surfaces. A resin bond locks the abrasive in place and dissipates heat to extend disc life. Rated to 12,000 RPM, it is built for high-speed angle grinders and disc sanders used in fabrication, weld blending, and surface prep work.

This disc is suited for both wet and dry sanding operations, making it versatile across metal fabrication shops, woodworking operations, and general surface conditioning tasks. The X-weight cloth backing resists tearing and edge wear under aggressive pressure, supporting sustained use on hard materials. It is a practical choice for technicians and tradespeople who need a reliable abrasive disc that mounts quickly and holds up through demanding finishing cycles.

Key Features

• Pressure-sensitive adhesive backing adheres to backup pads or steel platens and releases cleanly for fast disc changes
• X-weight cloth backing resists tearing and edge wear during aggressive material removal
• Aluminum oxide abrasive provides fast cutting and long service life across a range of surfaces
• Resin bond protects against heat damage to extend disc life
• Rated to 12,000 RPM for use with high-speed disc sanders and angle grinders
• Compatible with both wet and dry sanding applications

Compatibility

Designed for use with backup pads or steel platens that accept 6-inch PSA-backed sanding discs in wet or dry grinding and finishing applications.

Installation Notes

Mounting and disc changes should be performed with the tool powered off and fully stopped. Ensure the backup pad or platen surface is clean and free of debris before applying the PSA disc to achieve a secure bond. Do not exceed the 12,000 RPM speed rating of the disc. Inspect the disc for damage before each use and replace immediately if tears, edge fraying, or adhesive failure are observed.
