3M 7000000297 Microfinishing Film Disc 268L 3 Inch Ao

Product Description

The 3M 7000000297 is a coated abrasive microfinishing film disc designed for precise, close-tolerance surface finishing in production and repair applications. Built on a 3 MIL high-strength polyester film backing, micron-graded aluminum oxide mineral is resin-bonded to the substrate for consistent cut and durability across both wet and dry use. The disc measures 3 inches in diameter with a 7/8 inch arbor and features a hook and loop attachment system for fast disc changes and re-use. Technicians reach for this disc when defect repair, paint leveling, and final finishing require repeatable, uniform results.

This disc is suited for automotive refinishing, metal fabrication, and precision surface prep work where tight finish tolerances matter. The water-resistant polyester film backing makes it effective in wet sanding applications as well as dry finishing passes. Its color-coded design reduces the chance of selecting the wrong grade during multi-step finishing sequences. Paint prep technicians, body shop pros, and precision metalworkers are the primary users of this disc format.
