3M™ Microfinishing Film Roll 472L was designed for superfinishing and powertrain microfinishing. This roll helps achieve uniform, consistent finishes on parts where close tolerances are important.

Built for Microfinishing
On cylindrical parts, like automotive powertrain components, consistent and predictable finishes are key. 3M™ Microfinishing Film Roll 472L helps produce fine finishes and achieve close tolerances on parts like these. It can be used on a variety of substrates, including gelcoat, soft rubber, hard chrome, soft and hard composites, fiberglass, all metals and hard-filled rubber.

Silicon Carbide Mineral and Polyester Backing
We engineer Film Roll 472L 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 472L 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.

Get Close to the Close Tolerance
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 472L is a good match for workpieces that require precise and uniform cutting action.
