3M 7100112430 Hookit 360L Film Disc 3 Inch P800

Product Description

The 3M 7100112430 is a Hookit 360L coated abrasive film disc designed for fine sanding and finishing applications. It uses an aluminum oxide abrasive grain bonded to a durable film backing, making it well suited for work on plastics, gel coats, fiberglass, and polyurethane solid surface substrates. The disc measures 3 inches in diameter and carries a P800 grit rating, placing it firmly in the fine-finishing range. It is rated for up to 20,000 RPM. The film backing resists edge tearing and maintains close tolerances, making it a reliable choice in high-production shops and professional finishing environments.

This disc is used in automotive body, marine, and composite finishing applications where a consistent, fine scratch pattern is required before paint or topcoat. Its open coat construction reduces loading when working with softer materials such as gel coats, fiberglass composites, and solid surface panels. The Hookit attachment system allows fast disc changes without tools, supporting efficient workflow during production runs. Typical users include auto body technicians, marine refinishers, composite fabricators, and professional painters who need repeatable results across multiple passes.

Key Features

• Aluminum oxide abrasive grain delivers a fast cut and extended service life across a range of surface materials
• Film backing resists edge tearing and flexes consistently for close-tolerance finishing
• Open coat construction minimizes loading on soft or resinous substrates
• Hookit attachment system enables quick, tool-free disc changes and allows disc reuse
• P800 grit rating suited for fine sanding, scratch refinement, and pre-topcoat surface prep
• Rated to 20,000 RPM for compatibility with high-speed random orbital and straight-line sanders

Compatibility

Designed for use with Hookit-compatible random orbital and straight-line air sanders that accept 3-inch hook-and-loop discs. Suitable for sanding and finishing on plastics, gel coats, fiberglass, composites, and polyurethane solid surface materials.

Installation Notes

Attach the disc to a clean, dry Hookit-compatible backing pad before use and confirm the pad is free of debris that could cause uneven abrasion. Do not exceed the rated speed of 20,000 RPM. Inspect the disc before each use and discard if the abrasive layer shows separation, tears, or significant loading. Use appropriate respiratory protection when dry sanding composites, gel coats, or painted surfaces.
