3M 7010298859 Microfinishing Film Disc 366L 6 Inch Ao

Product Description

The 3M 7010298859 is a Hookita hook-and-loop microfinishing film disc in the 366L series, designed for precision surface finishing across a wide range of materials. Built on a durable polyester film backing, it carries micron-graded aluminum oxide abrasive that delivers a fast cut rate and a consistent, repeatable finish. The disc measures 6 inches in diameter, runs at up to 12000 RPM, and is configured for vacuum dust extraction. A load-resistant coating keeps the abrasive surface clear of debris during extended use, maintaining cut efficiency throughout the disc's service life. Licensed tradespeople and finishing specialists working in production or refinishing environments rely on this disc for controlled material removal and tight finish tolerances.

The 366L disc is suited for wood, solid surface composites, plastic, fiberglass, paint prep, coating and corrosion removal, primer, e-coat, and metal finishing applications. It fits into multi-step finishing workflows where consistent surface profiles are required between operations. The Hookita hook-and-loop attachment system allows fast disc changes without tools, making it practical for high-throughput environments where operators cycle through multiple grits. Both open coat and dust control configurations are available in the 366L line.

Installation Notes

Attachment requires a compatible 6-inch Hookita or hook-and-loop backup pad. Confirm the tool RPM rating meets or exceeds the disc maximum before mounting. Inspect the disc for tears or separation before each use and replace immediately if backing damage is observed. Do not exceed the rated speed of 12000 RPM.
