3M 7100142945 Hookit 360L Film Disc 5 Inch P600 Grit

Product Description

The 3M 7100142945 is a Hookit 360L coated film disc designed for fine sanding and finishing work on plastics, gel coats, fiberglass, composites, and polyurethane solid surface substrates. The disc uses aluminum oxide abrasive grain bonded to a durable film backing that resists edge tearing and holds a close tolerance finish under production conditions. At 5 inches in diameter with a P600 grit rating, it is suited for final-stage sanding passes where surface consistency matters. The open coat construction reduces loading and keeps the disc cutting cleanly throughout its service life. Licensed tradespeople and finishing technicians in marine, automotive, and industrial environments regularly spec this disc for high-volume material removal and prep work.

This disc is built for use in professional finishing environments where surface quality and throughput both matter. It fits Hookit-style backup pads and is rated for use at speeds up to 12000 rpm. Typical applications include sanding gel coat repairs on fiberglass panels, finishing solid surface countertop edges, and preparing composite substrates for coating. The film backing gives it an advantage over standard A-weight paper discs in conditions that cause premature edge failure, making it a practical choice for production shops running discs through repeated cycles.

Key Features

• Aluminum oxide abrasive grain delivers fast cut rate and consistent performance across a range of substrates
• Film backing resists edge tearing for longer disc life compared to standard paper-backed discs
• Open coat construction minimizes loading when sanding resins, gel coats, and solid surface materials
• Hookit attachment system allows fast disc changes and disc reuse during production runs
• P600 grit rating suited for fine finishing and pre-coat surface preparation
• Rated to 12000 rpm for use with standard random orbital and disc sanders

Compatibility

Designed for use with Hookit-style 5 inch backup pads on random orbital and disc sanders rated for coated abrasive film discs.

Installation Notes

Inspect the backup pad face for debris or damage before attaching the disc to ensure proper contact and even cut. Confirm the sander is rated at or below 12000 rpm before use. Power down and disconnect the sander from any air or electrical supply before changing discs. Follow all applicable workplace safety guidelines for abrasive tool use including eye and respiratory protection when sanding composites or gel coat materials.
