3M 7010359916 Hookit 360L Film Disc 5 Inch P320 Grit

Product Description

The 3M 7010359916 is a Hookit 360L coated film disc designed for fine sanding and finishing applications on plastics, gel coats, fiberglass, and polyurethane solid surface substrates. The disc uses aluminum oxide abrasive grain bonded to a durable film backing that resists edge tearing and delivers consistent, close-tolerance finishes. At 5 inches in diameter and P320 grit, it is well suited for high-production sanding operations where both cut rate and surface quality matter. The open coat construction reduces loading, extending usable disc life. The Hookit attachment system allows quick disc changes and reuse throughout the life of the disc.

This disc is used in production finishing environments where fine material removal and surface preparation are required. Typical applications include sanding composites, gel coats, fiberglass panels, and polyurethane solid surfaces. It is commonly used in automotive body shops, marine fabrication, and composite manufacturing settings where consistent scratch patterns and long disc life are priorities. The film backing provides an advantage over standard A-weight paper backings in high-wear conditions.

Key Features

• Aluminum oxide grain delivers fast cut rate and extended service life across a range of surface materials
• Durable film backing resists edge tearing and maintains consistent finish quality under production conditions
• Open coat construction minimizes loading on the disc surface for a more aggressive and sustained cut
• Hookit attachment system enables fast, tool-free disc changes and allows the disc to be removed and reattached for reuse
• Suitable for sanding and finishing on composites, gel coats, fiberglass, and polyurethane solid surface substrates

Compatibility

Designed for use with 5 inch Hookit backup pads and random orbital sanders that accept hook-and-loop disc attachment systems.

Installation Notes

Mount the disc onto a compatible 5 inch Hookit backup pad, ensuring full surface contact before operating the tool. Confirm the tool's rated speed does not exceed 12000 RPM before use. Inspect the disc for damage before each use and replace if backing or abrasive shows signs of deterioration. Proper backing pad condition is critical to achieving a flat, consistent finish.
