3M 7000045382 Hookit Film Disc 375L 5 Inch P800 Grit

Product Description

The 3M 7000045382 is a Hookit film-backed abrasive disc designed for surface finishing on a wide range of substrates. Built on a tear-resistant film backing, this 5-inch disc runs at up to 12,000 RPM and delivers a consistent, uniform scratch pattern at P800 grit. The aluminum oxide abrasive grain is open-coated with a load-resistant treatment that resists clogging from dust and swarf, keeping cut rate steady through the life of the disc. Professionals who need repeatable finish quality on contoured or flat panels will find this disc well-suited to the task.

This disc is intended for finish sanding and surface prep work where a fine, controlled scratch pattern is required. The film backing provides flexibility, making it especially effective on contoured surfaces and compound curves. The Hookit attachment system allows fast disc changes without adhesive tabs, reducing downtime during production finishing operations. Typical applications include automotive body refinishing, composite surface prep, and light metal finishing in shop environments.
