3M 7000120373 Microfinishing Film Disc 268L 5 Inch Ao

Product Description

The 3M 7000120373 is a coated microfinishing film disc engineered for fast-cutting abrasive action with precise, uniform, close-tolerance finishes. Aluminum oxide mineral is resin-bonded to a 3 MIL high-strength polyester film backing, giving this disc the rigidity and durability required for consistent stock removal. Rated to 12000 RPM and measuring 5 inches in diameter, it is designed for defect repair, surface leveling, paint preparation, and final finishing work. The hook and loop attachment system allows quick disc changes and reuse across compatible random orbital and disc sanders used in finishing and surface prep operations.

This disc is suited for trade and production finishing applications where close-tolerance surface quality is required. Its water-resistant polyester film backing supports both wet and dry use, making it adaptable to shop and field environments. The disc is color coded for straightforward grade identification, reducing the chance of selecting the wrong abrasive during multi-step finishing sequences. Typical users include auto body technicians, industrial finishing specialists, and surface prep professionals working on painted, coated, or composite substrates.
