The 3M 7000139515 is a PSA-backed abrasive film disc roll designed for precision polishing and fine finishing across a wide range of substrates. Built on a waterproof polyester film backing, this disc roll uses 3M microreplication technology to deliver consistent, repeatable surface finishes from pass to pass. The aluminum oxide mineral is arranged in a precise, uniform pattern rather than a random scatter, which controls cut rate and minimizes deep scratching during multi-step finishing sequences. Suitable for both wet and dry use, it connects to handheld or power tools via pressure-sensitive adhesive for fast pad changes on the job.
This disc roll is used in polishing and finishing applications on glass, acrylic, composites, painted surfaces, and other sensitive or hard-to-finish materials. The 5-inch diameter format fits standard 5-inch PSA backup pads common in automotive, aerospace, woodworking, and precision fabrication environments. Color-coding by grade helps technicians keep grades organized and reduces the chance of using the wrong abrasive step in a multi-stage process. The roll format is suited to operations that cut individual discs as needed to reduce waste and manage inventory.
Designed for use with standard 5-inch PSA backup pads on handheld and machine polishing tools. No specific model compatibility data was provided for this SKU.
Disc rolls of this type are installed by a finishing technician or abrasives operator using a standard 5-inch PSA backup pad mounted to an orbital, random-orbital, or rotary polisher. Before applying a new disc, ensure the backup pad face is clean and free of adhesive residue to achieve proper bond. When running wet, confirm the tool is rated for wet use and that the work area meets applicable safety requirements. Discard any disc showing tears, delamination, or loss of PSA tack before use.
