3M 7010325748 Hookit 360L Film Disc 5 Inch P400 Grit

Product Description

The 3M 7010325748 is a Hookit 360L coated abrasive film disc designed for fine sanding and finishing work on plastics, gel coats, polyurethane solid surfaces, fiberglass, and composites. It uses aluminum oxide abrasive grain bonded to a durable film backing that resists edge tearing and maintains consistent contact with the work surface. At P400 grit, it delivers a close-tolerance finish suitable for surface prep and final sanding stages. The open-coat construction reduces loading, extending usable disc life in high-production environments. The Hookit attachment system allows fast disc changes and reuse, reducing downtime during sanding operations.

This disc is well-suited for body shops, composite fabrication, marine refinishing, and solid surface finishing applications. The 5-inch diameter and P400 grit make it appropriate for detail sanding, finish prep, and surface leveling on gel coats and fiberglass panels. It is commonly used by professionals who require a consistent, repeatable finish across large surface runs. The film backing provides more uniform pressure distribution than standard A-weight paper, making it a preferred choice in production sanding environments where finish quality and disc longevity both matter.

Key Features

• Aluminum oxide abrasive grain delivers fast cut and consistent performance across multiple surface types
• Durable film backing resists edge tearing and outlasts standard A-weight paper-backed discs
• Open-coat construction reduces loading on the disc surface during extended use
• Hookit attachment system enables quick disc changes and supports disc reuse
• P400 grit suitable for fine sanding, finish prep, and surface leveling
• Effective on composites, gel coats, fiberglass, polyurethane, and solid surface materials

Compatibility

Designed for use with 3M Hookit random orbital and disc sanders that accept 5-inch hook-and-loop abrasive discs.

Installation Notes

Installation is performed by hand without tools — align the disc to the Hookit backup pad and press firmly to seat the hook-and-loop interface before operating the sander. Inspect the disc for loading, tears, or glazing before each use and replace as needed. Operate at or below the rated maximum speed of 12000 RPM. Ensure the workpiece is properly supported and secured before beginning any sanding operation.
