3M 7100015071 Microfinishing Film Disc 366L 5 Inch Ao

Product Description

The 3M 7100015071 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 polyester film backing, delivering a fast cut rate and a uniform, repeatable finish. The disc measures 5 inches in diameter and is rated for operation up to 12000 RPM. A load-resistant coating minimizes clogging from dust and debris, extending disc life and maintaining consistent cut performance throughout the pad life. This disc is suited for tradespeople and finishing professionals who require close-tolerance surface preparation.

The 366L disc is used in applications involving wood, solid surface composites, plastic, fiberglass, paint prep, coating and corrosion removal, primer, e-coat, and metal finishing. The Hookita hook and loop attachment system allows fast disc changes during multi-step finishing sequences, making it practical in production or field environments where turnaround time matters. It is available in both open coat and dust control configurations to match jobsite conditions.
