3M 7000045404 Hookit Film Disc 375L 6 Inch P500

Product Description

The 3M 7000045404 is a Hookit film-backed abrasive disc in the 375L series, designed for sanding and finishing operations where tear resistance and surface consistency are critical. Built on a durable film backing with a premium aluminum oxide abrasive grain, this disc delivers a fast cut rate and extended service life compared to paper-backed alternatives. The open-coat construction paired with a load-resistant coating keeps the disc clear of dust and debris during use, maintaining cut performance across the full life of the disc. Rated at 12000 RPM, it is suited for use with standard random-orbital and line sanders equipped with Hookit attachment systems.

This disc is used in automotive bodywork, metal fabrication, woodworking, and composite finishing applications where a uniform, swirl-free surface is required. The 6-inch diameter and P500 grit make it well-suited for intermediate finishing passes on flat and contoured panels. The film backing conforms to curved and irregular surfaces without tearing, which is especially useful on body lines and compound curves. Trade professionals in auto body, aerospace, and custom fabrication shops commonly spec this disc for final prep before sealer or topcoat application.

Installation Notes

Attach the disc firmly to a compatible Hookit backup pad before operating the sander. Confirm the tool RPM rating does not exceed the 12000 RPM disc rating before use. Inspect the disc for tears or loading before each use and replace if the abrasive surface is clogged or the film backing is compromised. Eye protection and appropriate respiratory protection should be worn during sanding operations per applicable safety standards.
