3M 7100010768 Hookit 360L Film Disc 3 Inch P800 Grit

Product Description

The 3M 7100010768 is a Hookit 360L coated abrasive film disc designed for fine sanding and finishing work on plastics, gel coats, fiberglass, composites, and polyurethane solid surface substrates. It features an aluminum oxide abrasive grain bonded to a durable film backing, which resists edge tearing and delivers a close-tolerance, consistent finish. Rated for up to 20000 RPM, this 3 inch diameter disc is suited for high-production environments where both speed and surface quality matter. The open coat construction reduces loading, and the Hookit attachment system allows fast disc changes without tools.

This disc is intended for finish sanding and surface preparation on composite panels, gel coat repairs, fiberglass bodywork, and polyurethane solid surfaces. It is commonly used in marine, automotive, and industrial finishing applications. At P800 grit, it delivers fine scratch patterns appropriate for prep work before sealing or topcoating. Technicians and finishing professionals working in production settings will find the film backing particularly useful where standard paper-backed discs tend to fail prematurely at edges.

Key Features

• Aluminum oxide grain provides fast cut and consistent performance across a range of surface materials
• Film backing resists edge tearing and outlasts standard A-weight paper-backed discs in production use
• Open coat construction minimizes loading when sanding soft or resinous materials
• Hookit attachment system enables quick disc changes and allows disc reuse over its service life
• P800 grit delivers fine finish scratch patterns suitable for pre-topcoat surface preparation
• Rated to 20000 RPM for compatibility with high-speed random orbital and rotary sanders

Compatibility

Designed for use with 3 inch Hookit hook-and-loop backup pads and compatible random orbital or rotary sanders that accept 3 inch hook-and-loop discs.

Installation Notes

Mount the disc onto a clean, compatible 3 inch Hookit backup pad, ensuring full contact across the disc face before use. Inspect the backup pad for worn or contaminated hooks that may reduce holding force at speed. Do not exceed the rated 20000 RPM maximum speed. Disconnect or power down the tool before attaching or removing discs.
