3M 7100015070 Microfinishing Film Disc 5 Inch 12000 Rpm

Product Description

The 3M 7100015070 is a Hookita Microfinishing Film Disc in the 366L series, designed for precision surface finishing across a wide range of materials. It uses micron-graded aluminum oxide abrasive bonded to a durable polyester film backing, delivering a fast cut rate and a consistent, uniform finish. The 5-inch disc spins at up to 12000 RPM and is built for multi-step finishing workflows where close tolerances and repeatable results are required. A load-resistant coating keeps the disc clear of dust and debris throughout use. Installers and finishing technicians working in fabrication, body shop, or industrial surface prep environments rely on this disc for dependable performance across substrates.

The 7100015070 is suited for surface finishing on wood, solid surface composites, plastic, fiberglass, and metal. It also handles paint prep, coating removal, corrosion removal, primer, and e-coat applications. The Hookita hook and loop attachment system allows fast disc changes during multi-step processes, making it practical for production environments where downtime between grits needs to stay minimal. Available in open coat and dust control configurations to match shop ventilation and material requirements.
