3M 7100086447 Abrasive Disc Roll 5 Inch P500 Grit

Product Description

The 3M 7100086447 is an abrasive disc roll in the Stikita 210U series, featuring open-coat aluminum oxide abrasive on a light A-weight paper backing. Each disc measures 5 inches in diameter and carries a P500 grit rating, making it suited for fine sanding and finishing work on a variety of surfaces. The roll format eliminates disc liners entirely, allowing faster grab-and-go access on the job. The pressure-sensitive Stikita adhesive backing attaches directly to compatible backup pads without clips or fasteners. Installers in woodworking, metal fabrication, auto body, and general finishing trades use these discs for controlled material removal and surface prep.

These discs are designed for lightweight finishing and fine sanding applications across residential and commercial trades. The open-coat construction reduces loading by keeping dust off the abrasive face and the workpiece, which extends usable life per disc and maintains a cleaner cutting surface throughout the pass. The roll comes in a minimum quantity of 4 rolls per order and is packaged in a compact format measuring 13 inches long, 8.8 inches wide, and 4.8 inches tall. The unit of measure is roll.

Installation Notes

These discs are installed by hand onto PSA-compatible backup pads mounted to orbital or random-orbital sanders. Ensure the backup pad surface is clean and free of debris before attaching each disc to maintain full adhesive contact. Disengage and power down the sander before changing discs. Discard any disc that shows visible tearing, delamination, or loss of abrasive.
