3M 7000045384 Hookit Film Disc 375L 6 Inch P800 Grit

Product Description

The 3M 7000045384 is a Hookit film-backed abrasive disc in the 375L series, designed for fine finishing work on a variety of substrates including metal, composite, and painted surfaces. The disc runs at up to 12000 RPM and features a P800-grit premium aluminum oxide abrasive grain that delivers a fast cut rate alongside extended disc life. The durable polyester film backing provides tear resistance and a consistent, uniform finish pass after pass. The load-resistant coating helps prevent dust and debris from clogging the abrasive surface, maintaining cut performance through the full life of the disc.

This disc is well suited for finish sanding on contoured and flat surfaces in automotive body, aerospace, and general metal fabrication work. The open-coat construction promotes an aggressive cut while the film backing conforms to curved and irregular profiles. The Hookit attachment system allows the disc to be removed and reattached quickly without tools, reducing changeover time during multi-step finishing operations. Sold individually, this 6-inch disc fits standard Hookit backup pads used in those trades.

Installation Notes

Mounting is performed by pressing the disc firmly onto a compatible Hookit backup pad until the hook-and-loop interface is fully engaged.
