3M 7000044740 Hookita 366L Film Disc 5 Inch 12000 Rpm

Product Description

The 3M 7000044740 is a Hookita 366L Microfinishing Film Disc designed for precision surface finishing across a wide range of materials. It features micron-graded aluminum oxide abrasive bonded to a durable polyester film backing, delivering a fast cut rate and a uniform, consistent finish. The disc measures 5 inches in diameter and is rated for up to 12000 RPM. A load-resistant coating helps prevent clogging from dust and debris, extending disc life and maintaining cut consistency throughout use. This disc is sold individually and is suited for trade professionals who require repeatable results across multi-step finishing workflows.

The 7000044740 is designed for use on wood, solid surface composites, plastic, fiberglass, metal, and painted or coated surfaces. Common applications include paint prep, primer sanding, e-coat finishing, and corrosion removal. The Hookita hook-and-loop attachment system makes it well suited for multi-step processes where discs are swapped frequently between grits. It is used in both production shop environments and field finishing work by auto body technicians, woodworkers, composites fabricators, and general metal finishers.
