Product Description

The 3M 7100049207 is a 6-inch Hookita Microfinishing Film Disc from the 3M 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 disc is rated for up to 12000 RPM and is built for multi-step finishing workflows where close tolerances and repeatable results are required. A load-resistant coating helps prevent clogging during use, extending disc life across demanding applications.

This disc is suited for use on wood, solid surface composites, plastic, fiberglass, and metal substrates. It also performs well in paint prep, coating and corrosion removal, primer work, and e-coat finishing. The Hookita hook and loop attachment system allows fast disc swaps between grits during multi-step finishing processes, making it a practical choice for production environments and professional finishing operations.
