3M 7000044970 Hookita 366L Film Disc 3 Inch Ao

Product Description

The 3M 7000044970 is a Hookita 366L Microfinishing Film Disc designed for precision surface finishing across a wide range of materials. Built with micron-graded aluminum oxide abrasive bonded to a durable polyester film backing, this 3-inch disc delivers a fast cut rate and a consistent, uniform finish. The load-resistant coating keeps the disc clear of dust and debris during use. It is suited for professional finishing work on wood, solid surface composites, plastic, fiberglass, metal, primer, e-coat, paint prep, and corrosion removal. Installers and finishing technicians working in production or refinishing environments rely on this disc for repeatable, close-tolerance results.

This disc fits vacuum-compatible random orbital and disc sanders commonly used in automotive refinishing, woodworking, composite fabrication, and metal surface preparation. The 3-inch diameter suits detail work and contoured surfaces where precision is critical. The Hookita hook and loop backing makes it practical for multi-step finishing sequences, allowing fast disc changes between grits without downtime. It is appropriate for both shop and field use wherever a controlled, fine finish is required before coating or final inspection.

Installation Notes

Attach the disc to a compatible hook and loop vacuum-port sander before powering the tool.
