3M 7000120256 Hookita 360L Film Disc 6 Inch P500

Product Description

The 3M 7000120256 Hookita 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 uses an aluminum oxide abrasive grain bonded to a durable film backing, delivering a consistent, close-tolerance finish at up to 10,000 RPM. The open coat construction reduces loading during use, keeping the disc cutting efficiently throughout its service life. This disc is well suited to high-production finishing environments where disc longevity and surface consistency are critical.

This disc is intended for use on grinders, sanders, and finishing tools equipped with a hook-and-loop (Hookita) attachment system. Common applications include surface prep and finish sanding on marine gel coats, fiberglass panels, composite materials, and polyurethane solid surfaces. At 6 inches in diameter and P500 grit, it is appropriate for intermediate-to-fine finishing passes where scratch pattern control matters. Automotive body technicians, marine finishers, composite fabricators, and production sanding operators are the primary users.

Key Features

• Aluminum oxide abrasive grain provides fast cut rate and extended service life across a range of surface materials
• Film backing resists edge tearing and outlasts standard A-weight paper-backed discs in high-production use
• Open coat construction minimizes loading on soft or resinous substrates such as gel coats and polyurethane surfaces
• Hook-and-loop (Hookita) attachment allows fast disc changes and supports disc reuse for the full usable life
• Rated to 10,000 RPM for compatibility with common random orbital and disc sanding equipment
• Suitable for sanding and finishing composites, fiberglass, gel coats, plastics, and solid surface materials

Compatibility

Designed for use with hook-and-loop (Hookita) backing pads accepting 6-inch diameter discs. Compatible with random orbital sanders, disc sanders, and finishing tools rated to 10,000 RPM or higher. Verify backing pad diameter and attachment type before use.

Installation Notes

Attach the disc firmly to a clean, dry hook-and-loop backing pad before operating the tool. Confirm the tool RPM rating does not exceed the 10,000 RPM maximum disc speed rating. Inspect the disc for tears or loading before each use and replace when abrasive performance drops off. Always wear appropriate eye protection and dust respiratory protection when sanding composites, fiberglass, or gel coat materials.
