3M 7000000329 Microfinishing Film Roll 362L 15 Micron

Product Description

The 3M 7000000329 is a precision microfinishing film roll in the 362L series, designed for fast-cutting abrasive work where tight tolerances and uniform surface finish are required. It features a high-strength polyester film backing with resin-bonded aluminum oxide abrasive at a 15 micron grade. The anti-loading free-cut coating helps maintain consistent cut rate across extended use. This roll measures 4 inches wide by 150 feet long and is wound on a 3-inch keyed core. It is used by machinists, automotive technicians, and finishing specialists working on metal, plastic, and composite surfaces.

The 362L roll is well suited for precision finishing applications including roll superfinishing, automotive powertrain component finishing, paint spot repair, and surface preparation on plastics, fiberglass, wood, and solid surfaces. The keyed core design is compatible with standard film finishing equipment that accepts 3-inch keyed arbors. The 15 micron aluminum oxide grade delivers consistent material removal and a close-tolerance surface profile appropriate for both production and repair environments.
