3M 7010326443 Hookita Microfinishing Film Disc 6 Inch

Product Description

The 3M 7010326443 Hookita Microfinishing Film Disc 366L is a coated abrasive disc engineered for precision finishing across a wide range of surfaces. Built on a durable polyester film backing, it carries micron-graded aluminum oxide abrasive that delivers a fast cut rate and a consistent, uniform finish. The disc is rated at 12000 RPM and measures 6 inches in diameter. It is designed for professional use in automotive, woodworking, composites, and metal fabrication environments, and is typically installed and operated by skilled tradespeople and finishing technicians who require close-tolerance surface control.

This disc is suited for multi-step finishing workflows on wood, solid surface composites, plastic, fiberglass, paint prep, coating and corrosion removal, primer, e-coat, and metal surfaces. The Hookita hook and loop attachment system makes it practical for rapid disc changes during sequential finishing operations, reducing downtime between grits. Its load-resistant coating helps maintain cutting performance in dusty or debris-heavy conditions common to production and shop environments.
