3M 7100028668 Hookit 360L Sanding Disc 5 Inch P280

Product Description

The 3M 7100028668 is a 5-inch Hookit 360L Clean Sanding Disc designed for precision surface preparation where dust control and consistent finish quality are critical. The disc features a multi-hole pattern that evacuates dust more effectively than standard 5- or 6-hole designs, increasing both cut rate and disc life. An open-coat, load-resistant aluminum oxide abrasive layer resists clogging and maintains cutting efficiency throughout the life of the disc. A durable film backing provides tear resistance and delivers a close-tolerance finish. This disc is used by body shop technicians, finish carpenters, and paint prep professionals working on wood, metal, and composite surfaces.

The 360L disc is suited for finish sanding applications in both automotive and woodworking environments. The P280 grit level makes it appropriate for final prep work before sealing or topcoat application. The multi-hole pattern does not require alignment with the backing pad holes, which speeds up disc changes and reduces downtime during production work. The Hookit attachment system allows quick removal and reattachment, supporting disc reuse across multiple passes.

Key Features

• Multi-hole dust evacuation pattern outperforms standard 5- and 6-hole disc designs
• Open-coat, load-resistant abrasive coating resists clogging for sustained cut performance
• No hole alignment required with backing pad, enabling fast disc changes
• Aluminum oxide abrasive cuts faster and lasts longer than garnet abrasives
• Durable film backing is tear-resistant and supports close-tolerance finishing
• Hookit attachment system supports disc reuse throughout full disc life

Compatibility

Designed for use with Hookit-compatible 5-inch random orbital and disc sanding pads. No hole alignment with the pad is required due to the 360L multi-hole pattern design.

Installation Notes

Attach to a Hookit-compatible 5-inch backing pad by pressing the disc firmly onto the pad surface until secure. Inspect the disc before each use and replace if abrasive is worn or backing is compromised. Operate sanding equipment according to the tool manufacturer's RPM rating for the disc diameter. Ensure adequate dust collection is connected when using in enclosed spaces.
