The 3M Xtract Cubitron II Hookit Clean Sanding Film Disc 775L 64264 is a 5-inch, 180-grit disc designed for paint preparation, feather-edging, refining, and blending on automotive and industrial surfaces. The Xtract proprietary multi-hole pattern provides superior dust extraction to prevent loading and boost productivity. Cubitron II precision-shaped grain delivers twice the abrasion life and cut speed of conventional abrasives. Durable film backing resists tearing. The Hookit system allows quick disc changes on any 5-inch random orbital sander. Sold in 50-disc packs.
What is the difference between the 64264 and the 31374?
Both are Cubitron II 6-inch discs at 180+, but the 64264 is the 5-inch 775L with the Xtract multi-hole pattern optimized for dust extraction, while the 31374 is a 6-inch disc. The 64264 is specifically engineered for clean sanding on paint and topcoats.
What surfaces does the 775L work well on?
The 775L is suitable for all metals, aluminum, carbon steel, composites, wood, fiberglass, gelcoat, topcoats, and paint. It is particularly effective for feather-edging, blending, and surface prep before primer or topcoat application.
How does the Xtract multi-hole pattern compare to standard holes?
The Xtract proprietary hole pattern is engineered to maximize dust extraction for the specific particle sizes generated during paint and topcoat sanding. This reduces loading and extends disc life compared to discs with fewer or differently positioned holes.
Is 180+ grit appropriate for bare metal work?
At 180+ you can do final stock removal and feather-edging on metal but it may not be aggressive enough for heavy material removal. For initial bare metal work use 80+ or 120+ first, then refine with 180+ before priming.
