3M 7000118890 Psa Cloth Disc 348D 18 Inch 60 Grit

Product Description

The 3M 7000118890 is a pressure-sensitive adhesive (PSA) coated cloth sanding disc in the 348D series, designed for heavy-duty material removal in industrial and trade grinding applications. The disc measures 18 inches in diameter and carries a 60-grit aluminum oxide abrasive bonded with a resin system that resists heat buildup to extend disc life. It mounts to a backup pad or steel platen using its PSA backing, which adheres firmly during use and releases cleanly for fast swaps. Rated to 2000 RPM, this disc is suited for aggressive stock removal on metal, wood, and composite surfaces in production or job-shop environments.

This disc is built for high-volume sanding operations where downtime for abrasive changes is a cost factor. The X-weight cloth backing resists tearing and edge wear under aggressive pressure, making it appropriate for floor grinding, wide-belt platen work, and large-surface preparation tasks. It performs in both wet and dry operating conditions, giving finishing and fabrication shops flexibility in process setup. Licensed trades including flooring installers, fabricators, and industrial maintenance techs are the primary users of discs in this size class.

Compatibility

Designed for use with backup pads or steel platens that accept 18-inch PSA-mount sanding discs in wet or dry disc grinding and surface preparation equipment.

Installation Notes

Ensure the machine is fully powered down and the disc has come to a complete stop before removing or mounting abrasive discs. Clean the backup pad or platen surface of debris and old adhesive residue before applying the PSA disc to ensure proper adhesion and safe operation. Verify the machine's rated RPM does not exceed the disc's 2000 RPM maximum before startup. Follow applicable ANSI abrasive safety standards and the equipment manufacturer's guarding requirements when operating large-diameter disc equipment.
