3M 7000045400 Hookit Film Disc 375L 5 Inch P1000 Grit

Product Description

The 3M 7000045400 is a Hookit film-backed abrasive disc engineered for fine finishing work on a range of substrates. The disc uses premium aluminum oxide grain in an open-coat construction that cuts aggressively while resisting loading from dust and debris. At P1000 grit, it is suited for final scuff sanding, surface prep, and finish leveling. The durable film backing resists tearing and flexes to follow contoured surfaces, delivering a consistent, uniform finish on each pass. A load-resistant coating extends disc life by keeping the cutting surface clear during use.

This disc is used in body shop, metal fabrication, composite finishing, and surface preparation applications. The Hookit attachment system allows quick disc changes and repositioning without tools, supporting high-volume workflows where efficiency matters. The 5-inch diameter fits standard Hookit-compatible random orbital and orbital sanders common in automotive and industrial finishing environments. P1000 grit is appropriate for fine finishing passes, deglossing, and surface conditioning before topcoat application.

Key Features

• Premium aluminum oxide abrasive grain for fast cut rate and extended product life
• Open-coat construction resists loading and keeps the disc cutting cleanly
• Durable film backing provides tear resistance and flexibility on contoured surfaces
• Hookit attachment system enables fast, tool-free disc changes and reuse
• Load-resistant coating helps prevent clogging during use
• Delivers a consistent, uniform finish across multiple substrate types

Compatibility

Designed for use with 5-inch Hookit-compatible random orbital and orbital sanders that accept hook-and-loop backed abrasive discs.

Installation Notes

Installation and disc changes should be performed with the sander powered off and unplugged or with the air supply disconnected. Verify that the backup pad is clean and that the hook-and-loop surface is free of debris before attaching the disc to ensure proper adhesion. Operate the disc at or below the rated maximum speed of 12000 rpm. Discard any disc that shows signs of tearing, separation, or uneven wear that could affect finish quality or operator safety.
