3M 7000120226 Hookit 360L Film Disc 5 Inch P220 Grit

Product Description

The 3M 7000120226 is a Hookit 360L coated abrasive film disc designed for fine sanding and finishing work on plastics, gel coats, fiberglass, and polyurethane solid surface substrates. At 5 inches in diameter with a P220 grit rating, this disc uses aluminum oxide abrasive grain bonded to a durable film backing. The film backing delivers close-tolerance, consistent finishes while resisting edge tearing better than standard A-weight paper backings. At a rated speed of 12,000 RPM, it suits high-production sanding environments where disc longevity and cut consistency matter.

This disc is built for automotive refinishing, marine, and composite fabrication applications where fine surface preparation is required. It performs on gel coats, fiberglass layups, composites, and polyurethane solid surfaces. The open coat construction reduces loading during use, making it well suited to gummy or resinous materials. The Hookit attachment system allows quick disc changes and disc reuse, supporting efficient workflow on production finishing lines or detail sanding tasks.

Key Features

• Aluminum oxide abrasive grain provides fast cut and extended service life across a range of surfaces
• Durable film backing resists edge tearing and outlasts standard A-weight paper-backed discs
• Open coat construction reduces loading on resinous and composite materials
• Hookit hook-and-loop attachment allows fast disc changes and supports disc reuse
• P220 grit rating suited for fine sanding and finishing passes
• Rated to 12,000 RPM for compatibility with high-speed random orbital and disc sanders

Compatibility

Designed for use with 3M Hookit hook-and-loop backup pads accepting 5-inch coated abrasive discs. Suitable for sanding and finishing on composites, gel coats, fiberglass, and polyurethane solid surface materials.

Installation Notes

Mount to a compatible 5-inch Hookit backup pad before use. Confirm the backup pad and sander are rated to at least 12,000 RPM before operating at full speed. Inspect the disc for damage before each use and replace if the film backing shows tears or the abrasive layer is worn through. Use appropriate respiratory protection when sanding composite or fiberglass materials per applicable safety guidelines.
