3M 7000118918 Psa Cloth Sanding Disc 348D 1 Inch P240

Product Description

The 3M 7000118918 is a PSA cloth sanding disc in the 348D series, designed for heavy-duty material removal in grinding and finishing applications. The disc measures 1 inch in diameter and carries a P240 grit aluminum oxide abrasive, which cuts fast and maintains a long service life across a wide range of surfaces. A pressure-sensitive adhesive backing bonds securely to a backup pad or steel platen and releases cleanly, keeping changeovers fast. The resin bond system protects the abrasive layer from heat buildup, extending disc life during sustained use. Rated to 20000 RPM, this disc is suited to high-speed portable tooling used by metal fabricators, machinists, and finishing technicians.

The 348D disc is intended for both wet and dry sanding applications on metal, wood, and composite surfaces. Its X-weight cloth backing resists tearing and edge wear under aggressive stock removal conditions, making it appropriate for production environments where consistent cut rate and disc longevity matter. The 1 inch format fits small-diameter backup pads and inline tools commonly used for precision grinding, burr removal, and surface blending in tight or contoured areas.

Key Features

• Pressure-sensitive adhesive backing adheres to backup pads or steel platens and allows clean, fast removal for quick disc changes
• X-weight cloth backing resists tearing and edge wear during aggressive applications
• Aluminum oxide abrasive delivers fast cut rate and long service life across multiple surface types
• Resin bond system dissipates heat to protect the abrasive layer and extend disc life
• Rated to 20000 RPM for compatibility with high-speed portable tools
• Suitable for both wet and dry sanding operations

Compatibility

Designed for use with backup pads and steel platens that accept 1 inch PSA sanding discs in portable and benchtop grinding or finishing tools.

Installation Notes

Ensure the backup pad or steel platen surface is clean and free of debris before applying the PSA disc to achieve full adhesive contact. Power down and disconnect the tool from its power source before mounting or removing any abrasive disc. Confirm the tool spindle speed does not exceed the 20000 RPM rating marked on the disc. Wet application setups should use tooling and platens rated for wet operation.
