3M 7100048223 Hookit 255L Disc 6 Inch P320 Grit

Product Description

The 3M 7100048223 is a Hookit 255L coated abrasive disc designed for fast cutting and close-tolerance finishing on wood, paint prep, and defect repair work. Built on a flexible film backing with aluminum oxide abrasive grain, this disc delivers a consistent finish and greater tear resistance than comparable paper-backed products. The open-coat construction and load-resistant coating work together to reduce disc clogging, extending disc life in high-production environments. At 6 inches in diameter with a P320 grit rating and a maximum speed of 12,000 RPM, it is engineered for use with Hookit-compatible random orbital and DA sanders.

This disc is suited for professional finishing applications in automotive refinishing, woodworking, and general surface prep. The P320 grit makes it appropriate for final sanding stages, paint defect removal, and light stock removal before clear coat or topcoat application. The Hookit attachment system allows for quick disc changes and reuse, which improves throughput in production-level shops. It is typically used by auto body technicians, finish carpenters, and paint prep professionals.

Installation Notes

Ensure the sander is powered off and disconnected before changing discs. Press the disc firmly against the sander pad to engage the hook-and-loop interface fully before operation.
