3M 7010359913 Hookit 360L Film Disc 3 Inch P320 Grit

Product Description

The 3M 7010359913 Hookit 360L Film Disc is a coated abrasive disc designed for fine sanding and finishing on plastics, gel coats, fiberglass, composites, and polyurethane solid surface substrates. It features aluminum oxide abrasive grain bonded to a durable film backing, delivering consistent cut rates and close-tolerance surface finishes. The film backing resists edge tearing and outperforms standard A-weight paper backings in high-production settings. The open coat construction reduces loading, keeping the disc cutting aggressively throughout its service life. Rated at 20000 RPM, this 3 inch disc is sized for right-angle and random orbital tools used in body, marine, and composites finishing work.

This disc is suited for sanding and finish work on composite panels, fiberglass laminates, gel coat surfaces, polyurethane solid surfaces, and painted plastics. It is commonly used in marine fabrication, automotive body shops, and composite manufacturing environments where consistent finish quality and disc longevity are required. The Hookit attachment system allows quick disc changes and reuse, making it practical for high-volume production workflows where downtime between disc changes must be minimized.

Key Features

• Aluminum oxide abrasive grain provides fast cut and consistent performance across a range of surface materials
• Durable film backing resists edge tearing and delivers longer service life compared to paper-backed discs
• Open coat construction reduces loading on the disc face for a more aggressive, sustained cut
• Hookit attachment system enables fast, tool-free disc changes and supports disc reuse
• Suitable for gel coats, fiberglass, composites, plastics, and polyurethane solid surfaces
• 3 inch diameter fits standard right-angle and random orbital finishing tools

Compatibility

Designed for use with Hookit-compatible random orbital and right-angle sanding tools that accept 3 inch hook-and-loop abrasive discs.

Installation Notes

Mounting and removal require no tools — press the disc firmly onto a clean, dry Hookit backing pad before use. Inspect the backing pad for wear or contamination before attaching a fresh disc, as a damaged pad reduces adhesion and can cause disc separation at speed. Do not exceed the rated 20000 RPM maximum operating speed. Operators should wear appropriate respiratory protection when sanding composites, gel coats, or polyurethane materials per applicable safety regulations.
