3M 00959 Hookit Gold 255L Film Disc 5" P320 Grit Hook and Loop 100-Pack

The 3M Hookit Gold Film Disc 255L (MPN: 00959) is a premium 5-inch, P320-grit hook-and-loop sanding disc designed for fast cut-rate performance and a uniform, close-tolerance finish on wood, paint prep, and defect repair applications. Sold in a convenient 100-disc box, these discs are engineered for both professional and high-production environments.

Built on a tough, flexible film backing, the 255L delivers greater tear-resistance than comparable paper-backed products, making it an ideal choice wherever durability and consistency matter. The aluminum oxide abrasive grain self-fractures during use to continually expose fresh cutting edges, maintaining an aggressive cut throughout the disc's life.

Key Features:

• Aluminum oxide abrasive — fast cut-rate, long life, and professional-grade performance on wood, metal, and painted surfaces
• Flexible film backing — provides a consistent, close-tolerance finish with greater tear-resistance than paper
• Hookit hook-and-loop attachment — attaches and removes quickly from random orbital sander backup pads; discs can be reused multiple times until fully worn
• Open coat construction — abrasive grains are spaced to help evacuate sanding dust and debris, reducing disc loading
• Load-resistant coating — further prevents dust and debris from clogging the cutting surface
• Resin bonded — engineered for reliable performance under high heat and pressure
• P320 grit — fine finishing grit ideal for final paint prep, scuff sanding, and surface refinement
• 100 discs per box — high-count packaging for production efficiency

The 3M Hookit Gold 255L is preferred in applications where adhesive-backed discs such as the 3M Stikit may be too aggressive, as the Hookit system consistently delivers finer finishes. The hook-and-loop design also makes these discs a reliable choice in environments where adhesive-backed discs may be compromised by dust, dirt, or debris. Compatible with standard 5-inch hook-and-loop backup pads on random orbital sanders (backup pad sold separately).
