3M 7000118894 Psa Abrasive Disc 12 Inch 100 Grit

Product Description

The 3M 7000118894 is a pressure-sensitive adhesive (PSA) abrasive disc designed for material removal and surface finishing in shop and production environments. It measures 12 inches in diameter and carries a 100-grit aluminum oxide abrasive, placing it in the fine grade range. The disc uses an X-weight cloth backing, which provides the stiffness and durability needed for demanding grinding and finishing passes. The PSA mount allows fast, tool-free attachment to compatible platens. Aluminum oxide cuts aggressively across a wide range of base materials and maintains consistent performance through extended use. Licensed trades and skilled fabricators rely on this disc for controlled stock removal without excessive heat buildup.

This disc is suited for bench top motor applications and random orbital sanders where a 12-inch PSA platen is used. It is commonly installed in metal fabrication shops, woodworking operations, and general manufacturing environments where consistent, repeatable surface finish is required. The flexible cloth backing conforms slightly to workpiece contours, making it useful for both flat and mildly irregular surfaces. No vacuum holes are included, so it is intended for solid-platen use rather than dust-extraction setups.

Key Features

• 12-inch diameter PSA disc for fast, adhesive-mount attachment to compatible platens
• 100-grit aluminum oxide abrasive in the fine grade range for controlled material removal
• X-weight cloth backing provides rigidity and resistance to tearing under load
• Flexible construction allows the disc to conform to slightly irregular workpiece surfaces
• Compatible with bench top motors and random orbital sanders
• No vacuum holes — designed for solid-platen use

Compatibility

Designed for use with bench top motors and random orbital sanders equipped with a 12-inch PSA-style platen. No vacuum-hole pattern is present, so this disc is not intended for dust-extraction platen systems.

Installation Notes

Ensure the sander or motor platen is clean and free of adhesive residue before mounting the disc. Peel the PSA liner and press the disc firmly onto the platen, working from the center outward to eliminate air pockets. Power down and de-energize all equipment before changing discs. Dispose of worn discs per facility safety procedures and inspect the platen for damage before installing a new disc.
