3M 7100103336 Abrasive Disc Roll 5 Inch P320 Grit

Product Description

The 3M 7100103336 is a Stikit 216U coated abrasive disc roll designed for fast material removal and fine finishing on a wide range of surfaces. Built with aluminum oxide mineral on an A-weight light paper backing, this disc roll delivers consistent cut and long abrasive life. The P320 grit rating makes it well suited for finish sanding and surface preparation work. The roll format and pressure-sensitive adhesive backing allow quick, liner-free attachment to a compatible Stikit backup pad, reducing downtime between disc changes and keeping work moving efficiently.

This disc roll is used in woodworking, metal fabrication, auto body, and general surface finishing applications where a fine grit is needed for final prep or between-coat sanding. The 5-inch diameter fits standard Stikit backup pads sold separately. Open coat construction reduces dust loading on the abrasive surface, extending usable disc life on materials that tend to generate fine particles or residue during sanding.

Key Features

• Roll format eliminates disc liners, speeding up disc changes and improving productivity
• Aluminum oxide mineral cuts fast and holds up well across a broad range of workpiece materials
• A-weight paper backing supports flexibility needed for finishing and light stock removal
• Open coat construction reduces loading and keeps the abrasive surface cutting longer
• Load-resistant coating extends abrasive grain life and maintains cut rate over the disc lifespan
• Pressure-sensitive adhesive backing attaches directly to Stikit backup pads without additional fasteners

Compatibility

Designed for use with Stikit backup pads that accept 5-inch adhesive-backed abrasive discs. Backup pad sold separately.

Installation Notes

Application of this disc roll requires a compatible Stikit backup pad mounted to a random orbital or disc sander. Ensure the backup pad surface is clean and free of debris before attaching each disc to achieve full adhesive contact. Operate the sander at speeds appropriate for the material being worked and the grit being used. Inspect each disc before use and discard any disc showing tears, uneven wear, or loss of adhesive integrity.
