Product Overview
The 3M™ Microfinishing Film Roll 472L is a fast-cutting abrasive for precise, uniform, close-tolerance finishes.On cylindrical parts like automotive powertrain components, consistent and predictable finishes are key. The 3M Microfinishing Film Roll 472L helps produce fine finishes and achieves 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, fibreglass, all metals, and hard-filled rubber. The 3M Microfinishing Film Roll 472L is engineered 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. It 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, the 3M Microfinishing Film Roll 472L is a good match for workpieces that require precise and uniform cutting action.
