3M 7000118910 Psa Disc P120 Fine 0.5 Inch Aluminum Oxide

Product Description

The 3M 7000118910 is a coated PSA (pressure-sensitive adhesive) abrasive disc from the 348D series, designed for precision grinding and finishing applications in trade and industrial environments. The disc measures 0.5 inches in diameter and uses aluminum oxide abrasive formed to a P120 fine grit rating. It is mounted on a cloth backing at X weight, which provides durability and flexibility during surface finishing. The adhesive backing allows for fast disc changes on compatible PSA-style backup pads. This disc is rated for a maximum speed of 20,000 RPM, making it suitable for high-speed rotary tools used by machinists, fabricators, and finishing technicians.

The 3M 7000118910 is used in metalworking, fabrication, and surface preparation applications where a fine-grit, small-diameter disc is required. Its 0.5-inch size makes it appropriate for detail work, tight radii, and confined surfaces that larger discs cannot reach. The P120 grit level suits intermediate finishing passes where surface scratch reduction is the goal prior to finer finishing steps. Trade professionals in metal fabrication, automotive refinishing, and general industrial maintenance will find this disc suited to manual and machine-assisted finishing workflows.

Key Features

• Aluminum oxide abrasive for consistent cutting performance on metal and hard surfaces
• P120 fine grit rating for intermediate finishing and scratch reduction
• Pressure-sensitive adhesive backing for quick mounting and removal on PSA backup pads
• X-weight cloth backing provides durability and resistance to tearing under load
• Rated to 20,000 RPM maximum speed for use with high-speed rotary tools
• Available in quantities of 50 discs per inner pack and 500 discs per case

Compatibility

Designed for use with PSA-style backup pads that accept 0.5-inch abrasive discs. Confirm backup pad diameter and adhesive-style compatibility before installing.

Installation Notes

Installation of PSA discs should be performed with the rotary tool powered off and unplugged or with the air supply disconnected. Ensure the backup pad surface is clean and free of debris before applying the disc to achieve proper adhesion. Do not exceed the 20,000 RPM maximum rated speed. Inspect the disc for damage before each use and discard any disc showing tears, delamination, or loss of abrasive material.
