3M 7010408050 Hookit Film Disc 5 Inch P800 Grit Ao

Product Description

The 3M 7010408050 is a Hookit 360L coated abrasive 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, delivering a fast cut with consistent finish quality. The open coat construction reduces loading and helps maintain cutting efficiency over the life of the disc. Rated for operation up to 12,000 RPM, this 5 inch disc is built for high-production sanding environments where durability and reliability matter.

This disc is suited for automotive body work, marine finishing, composite fabrication, and solid surface refinishing. Typical applications include fine sanding between coats on gel coats and polyurethane surfaces, finish sanding fiberglass panels, and surface preparation on composites. The P800 grit level makes it appropriate for final preparation passes before topcoat application. Trade professionals including auto body technicians, marine refinishers, and composites fabricators are the primary users. Discs are sold in box quantities with a minimum order of 5 units.

Key Features

• Aluminum oxide abrasive grain delivers a fast cut and consistent performance across a range of surface materials
• Durable film backing resists edge tearing and provides closer finish tolerances than standard A-weight paper backings
• Open coat construction minimizes loading, extending usable disc life in high-production sanding
• Hookit attachment system allows fast disc changes and reuse throughout the disc life
• P800 grit suitable for fine finish sanding and pre-topcoat surface preparation
• Rated to 12,000 RPM for use with standard random orbital and DA sanders

Compatibility

Designed for use with 5 inch Hookit-compatible random orbital and disc sanders. Suitable for sanding and finishing on composites, gel coats, fiberglass, plastics, and polyurethane solid surface materials.

Installation Notes

Installation of this disc requires a 5 inch Hookit-style hook-and-loop backing plate on a compatible sander. Confirm the sander is powered off and unplugged before changing discs. Do not exceed the rated speed of 12,000 RPM. Inspect the disc and backing plate for damage before each use and discard any disc showing tears, delamination, or worn abrasive.
