3M 7000118869 Psa Cloth Sanding Disc 80 Grit 10 Inch

Product Description

The 3M 7000118869 is a PSA cloth sanding disc designed for heavy-duty material removal on metal, wood, and composite surfaces. It uses an aluminum oxide abrasive bonded with a resin system that resists heat buildup, extending disc life under sustained load. The pressure-sensitive adhesive backing attaches firmly to a backup pad or steel platen and releases cleanly for fast changeovers. The X-weight cloth backing handles aggressive grinding and finishing passes without tearing or edge fraying. Suitable for both wet and dry use, this disc fits standard disc grinder setups used by fabricators, maintenance techs, and metalworking professionals.

This disc is well suited for surface preparation, weld blending, rust removal, and stock removal on ferrous and non-ferrous metals as well as hardwoods. The 80 grit rating positions it in the medium-aggressive range, making it a common choice for initial material removal before moving to finer grits. The PSA mount system makes it a practical option on production lines or service environments where disc changes need to be quick and clean.

Key Features

• Pressure-sensitive adhesive backing adheres securely to backup pads and steel platens and removes cleanly without residue
• X-weight cloth backing resists tearing and edge wear under aggressive cutting conditions
• Aluminum oxide abrasive delivers fast cut rate and consistent performance across many surface types
• Resin bond protects against heat damage and extends disc service life

Compatibility

Designed as an OEM-style PSA sanding disc for use with 10 inch backup pads and steel platens on standard disc grinders and finishing machines.

Installation Notes

Disc installation requires no tools — peel the liner and press firmly onto a clean, dry backup pad or steel platen to ensure full adhesive contact. Power down and lock out the grinder before removing or mounting any disc. Inspect the backup pad for damage or debris before mounting; a contaminated or worn pad reduces adhesive hold and can cause disc separation under load. Follow applicable ANSI B7 safety standards for abrasive disc use, including the use of appropriate eye and face protection.
