3M 7010325357 Microfinishing Film Disc 268L 6 Inch Ao

Product Description

The 3M 7010325357 is a Hookit 268L Microfinishing Film Disc engineered for precise, close-tolerance surface finishing in professional metalworking, automotive, and industrial applications. The disc uses micron-graded aluminum oxide mineral resin-bonded to a 3 MIL high-strength polyester film backing. At 6 inches in diameter with a vacuum hole pattern and a maximum operating speed of 10000 RPM, it delivers fast, consistent stock removal while maintaining tight finish tolerances. The hook and loop attachment system speeds up disc changes and allows re-use across multiple passes. Technicians and finishing professionals reach for this disc when defect repair, paint leveling, and final surface prep demand repeatable, uniform results.

This disc is suited for wet or dry finishing operations on metal, painted surfaces, and composite materials. The water-resistant polyester film backing holds up in wet sanding environments without delaminating or losing abrasive bond. Color coding assists technicians in selecting the correct grit quickly on busy shop floors, reducing the chance of cross-contamination between finishing stages. Typical applications include automotive paint defect repair, precision leveling before topcoat, and final finishing passes where surface consistency is critical.

Installation Notes

This disc is installed and serviced by finishing technicians and machinists. Ensure the backing pad on the tool is clean and free of debris before attaching the disc to achieve proper hook and loop engagement. Confirm the tool RPM rating does not exceed 10000 RPM before operation. Inspect the disc before each use and discard if the abrasive layer shows signs of loading, tearing, or delamination.
