  • Silicon carbide grain in various grades
  • Durableand even 5mil Polyester film (PET) backing
  • Electrostatically oriented coating
  • Used for fine grinding

Microfinishing film rolls are flexible tools on a polyester film carrier material that are only used for fine finishing. Fine Finishing Film also achieves a grinding effect because of the oriented grain and can therefore be used for fine grinding.

Built for Microfinishing on cylindrical parts, like rollers and shafts, consistent and predictable finishes are key. 3M™ Microfinishing Film Roll 479L helps produce fine finishes and achieve close tolerances on parts like these. It can be used on a variety of substrates, including gel coat, ‎soft rubber, ‎hard chrome, ‎soft and hard composites, ‎fiberglass, all metals, and hard-filled rubber. We engineer Film Roll 479L by adhering micron-graded silicon carbide mineral to polyester film using a resin bond. Silicon carbide mineral is very hard and fractures easily, resulting in freshly exposed sharp edges that cut extra fast and produce a smooth, professional-looking finish. While it wears faster than aluminum oxide, it produces a brighter finish. Roll 479L is available in a variety of grades, so operators can tailor the grade to their part. The high-strength polyester backing has uniform caliper thickness throughout its length, which is helpful when close tolerances are important. Across industries, from transportation to heavy equipment, from general industrial to aerospace, professionals value part integrity and consistency. Combining the strength of a polyester film backing with the fine and acute cutting qualities of micron-graded silicon carbide, 3M™ Microfinishing Film Roll 479L is a good match for workpieces that require precise and uniform cutting action.
