An aluminum oxide micron roll resin bonded to a 5 mil polyester film backing. The backing has a friction grip coating for slip resistance. Precision finishing of cylindrical surfaces such as automotive camshafts & crankshafts.

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

Suggested Applications
