3M 7100122790 Hookit 260L 3 Inch P600 Abrasive Disc

Product Description

The 3M 7100122790 is a Hookit 260L Purple Finishing Film Abrasive Disc engineered for surface finishing work on clear coat and painted panels. The disc uses aluminum oxide abrasive bonded with a specially formulated coating that cuts fast, resists loading, and minimizes pigtail defects that require additional correction steps. At 3 inches in diameter and P600 grit, this disc falls in the fine finishing range, making it suitable for final-stage leveling before polish. A flexible film backing increases conformability to curved and contoured surfaces. The Hookit attachment system allows fast disc changes without adhesive-backed pads or separate fasteners.

This disc is used in automotive refinishing and collision repair applications where controlled material removal and a consistent pre-polish surface are required. It is appropriate for use on clear coat, single-stage paint, and primer surfaces during the final leveling stages. Body technicians, paint prep specialists, and detailing professionals working in production or shop environments will find the disc suited to high-cycle finishing workflows. The film backing and coating combination make it effective on both flat panels and complex body contours.

Installation Notes

Mount the disc onto a compatible 3-inch Hookit backup pad before use. Ensure the backing pad surface is clean and free of debris to allow full disc adhesion and prevent premature release.
