The 3M 405-051144-21799 Stikit 363I PSA Disc Roll is a ready-to-use sanding solution designed for fast, consistent material removal on flat or contoured surfaces. This roll features a 5 in diameter disc with PSA (pressure-sensitive adhesive) backing, so discs can be quickly attached and replaced without tools. The abrasive is aluminum oxide, known for its versatility across a range of metals, paints, and plastics. Each disc is mounted on an extra-heavy F weight paper backing and is resin-bonded to help resist heat buildup during longer or more aggressive sanding passes. The 363I series is identified by a gold-colored disc and a grit rating of 80, suitable for initial leveling and surface finishing tasks. The roll format includes 100 discs per roll, with four rolls per case, enabling economical stock for shop environments that perform frequent surface prep.
Understanding the construction helps predict performance in real-world use. Aluminum oxide provides a solid balance of cut rate and durability for moderate material removal, while the resin-bonded coating helps maintain abrasive integrity under heat. The 5 in diameter and PSA attachment enable straightforward, dust-collection-friendly operation when used with compatible disc holders and sanding machines designed for roll-discs in this size and style. This product is positioned in janitorial and general maintenance workflows for surface prep prior to painting, coating, or finishing; ensure the backing and adhesive are appropriate for your substrate and the rotation speed is kept within the recommended limits to avoid glazing or tearing.
Compatibility notes: these discs are designed as 5 in PSA rolls suitable for machines configured to use PSA-coated discs. Each package consists of a roll with 100 discs, and the case contains four rolls, offering straightforward restocking and predictable packaging for inventory planning.
