3M 7010325578 Hookit 366L Microfinishing Film Disc 6 Inch

Product Description

The 3M 7010325578 is a 6-inch Hookit 366L Microfinishing Film Disc 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 10000 RPM and features a load-resistant coating that prevents dust and debris from clogging the abrasive surface during use. Licensed trades and finishing professionals rely on this disc for multi-step finishing workflows where tight tolerances and repeatable surface quality are required.

This disc is suited for use on wood, solid surface composites, plastic, fiberglass, metal, and coated surfaces including paint prep, primer, e-coat, and corrosion removal applications. The vacuum-compatible design supports dust extraction during use. Its Hookit hook and loop backing makes it a practical choice for high-cycle environments where discs need to be swapped quickly between grits or finishing stages.

Installation Notes

Mount the disc by pressing the Hookit backing firmly onto a clean, compatible hook and loop pad before powering the tool. Verify the tool RPM rating does not exceed 10000 RPM before operating.
