Our 3M™ Microfinishing Film Roll 362L quickly cuts, shapes and polishes, delivering close-tolerance finishes for precision tooling and machining applications. Available in 9-100 micron grades, aluminum oxide is electrostatically oriented and bonded to a polyester film backing. A Type S (smooth) backsize coating provides slip resistance for microfinishing machines.

We engineer 3M™ Microfinishing Film Roll 362L by bonding fine micron-graded aluminum oxide mineral to the film backing. Due to the fine grade ranges, it’s visually difficult to distinguish one grade from another, and because some applications may require multiple grits on the same machine simultaneously, our microfinishing film is color-coded to help avoid errors.
