3M 7000118907 Psa Cloth Disc 5 Inch 40 Grit 12000 Rpm

Product Description

The 3M 7000118907 is a pressure-sensitive adhesive (PSA) cloth sanding disc designed for heavy-duty material removal in industrial and shop environments. Built on an X-weight cloth backing, the disc withstands aggressive grinding and sanding without tearing or edge breakdown. The aluminum oxide abrasive cuts fast across a wide range of surfaces, and the resin bond protects the disc from heat buildup to extend working life. At 5 inches in diameter with a 40-grit cut rate, it is suited for rapid stock removal on metal, wood, and composites. Licensed trades and shop professionals install and replace these discs in high-cycle production and fabrication settings.

This disc is intended for use with backup pads or steel platens on orbital and rotary sanders rated up to 12000 RPM. The PSA backing adheres securely during operation and releases cleanly for fast disc changes, reducing downtime in production environments. It supports both wet and dry sanding applications, making it adaptable across finishing and surface-prep workflows in metalworking, woodworking, and general fabrication shops.

Compatibility

Designed for use with backup pads or steel platens on rotary and orbital sanders accepting 5 inch PSA-style sanding discs rated at or below 12000 RPM.

Installation Notes

Disc replacement should be performed with the sander powered off and unplugged or air supply disconnected. Ensure the backup pad or steel platen surface is clean and free of adhesive residue before applying a new disc to achieve full PSA contact. Do not exceed the 12000 RPM maximum speed rating marked on the disc. Follow applicable shop safety standards and wear appropriate personal protective equipment during sanding operations.
