Our 3M™ Microfinishing Film 372L quickly cuts, shapes and polishes, delivering uniform, close-tolerance finishes on parts used in metalworking applications.
Trust our 3M™ Microfinishing Film 372L to effectively finish a variety of automotive parts, like crankshafts, camshafts and transmission parts. It features a film backing and a Type S (smooth) backsize coating. The abrasive mineral is uniformly distributed over the backing, which helps produce a consistent finish each time you sand. Microfinishing – an important application for many operators – corrects the geometry of parts and creates fine finishes. Microfinishing can remove damaged or amorphous layers to improve the surface finish and roundness of the part. Our Microfinishing Film 372L is available in a variety of grades to help operators achieve desired finishes. We designed Type 2 film in a range of colours – reflective of each grade – for added value, helping operators reduce the risk for error.
