Highlights
  • Micron-graded aluminum oxide abrasive mineral provides precise, uniform, close-tolerance finishes
  • High friction coating on film backing (backsize) to prevent slipping
  • Ideal for metal, plastic finishing, and paint spot repair
  • Wide grade range for varying finish and stock removal requirements

3M™ Microfinishing Film Disc 372L is a fast cutting abrasive for precise, uniform, close-tolerance finish. A high friction coating on a strong, flexible 5 mil polyester film backing for use on metal and plastic surfaces, or for paint spot repair.

Micron-graded Mineral with Advantages
Available in fine micron-graded aluminum oxide, 3M™ Microfinishing Film Disc 372L (PDF, 65.52 Kb) features a flexible, film backing with a high-friction coating for better grip during use. This disc is available in varying diameters and center hole sizes. A polyester film backing is typically stronger than paper backings and more conformable to part profiles. It is waterproof so can be used in wet applications.

Fine Finishing, Powertrain Microfinishing, Superfinishing Performer
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. Operators should consider finish and stock removal requirements when selecting the right microfinishing film. (PDF, 347.73 Kb)
