3M 7000118116 Abrasive Disc Roll 5 Inch P400 Grit

Product Description

The 3M 7000118116 is a Stikita Paper Disc Roll in the 210U series, featuring open-coat aluminum oxide abrasive on a lightweight A-weight paper backing. Each disc measures 5 inches in diameter and carries a P400 grit rating, making it suited for fine sanding and finishing passes. The roll format eliminates disc liners entirely, letting technicians pull a disc and get to work without extra handling. The pressure-sensitive adhesive backing attaches quickly to compatible random orbital and disc sanders and removes cleanly when the disc is spent.

This disc roll is intended for lightweight sanding and finishing operations across a range of surfaces including wood, composites, and light metals. The P400 grit level is appropriate for final prep work, scuff sanding between coats, and surface conditioning prior to finishing. Trades that commonly use this product include finish carpenters, auto body technicians, industrial painters, and general maintenance professionals working in shop or field environments.

Installation Notes

Ensure the sander backing pad is clean and free of debris before applying each disc to achieve full adhesive contact. Press the disc firmly onto the pad before operation to prevent edge lifting during use. When removing a spent disc, peel slowly from one edge to avoid tearing. Store unused discs in a cool, dry location away from direct sunlight to preserve adhesive performance.
