    Anything extra you need to know

  • The 3M? Microfinishing Film Belt 472L was designed to deliver uniform, consistent finishes on parts where a close tolerance finish is essential
  • Micron-graded silicon carbide mineral is ideal for finishing of metals, plastics, wood and various other substrates
  • On flat parts, like die castings, and cylindrical or contoured workpieces such as auto parts ? consistent and predictable finishes are key
  • The 3M? Microfinishing Film Belt 472L helps produce fine finishes and achieve close tolerances by way of a durable, uniform film backing and micron-graded mineral
  • The 3M? Microfinishing Film Belt 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 fast and produce a bright 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 5 mil (0.13 m) polyester backing won?t yield or deflect when run, which is helpful when close tolerances are important
  • With a uniform backing, the abrasive maintains consistent contact with the workpiece to maintain critical geometries
  • 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 aggressive cutting qualities of micron-graded silicon carbide, the 3M? Microfinishing Film Belt 472L is a good match for workpieces that require precise and uniform cutting action.
  • What makes this product special

  • Micron-graded silicon carbide mineral cuts sharp and fast while producing extremely consistent, fine finishes
  • High-strength 5 mil polyester backing won?t yield or deflect when run, contributing to an aggressive cut
  • May be used on metal, plastic, wood and various other substrates
  • Open coat construction reduces loading to maintain a consistent, sharp cut and extends disc life for greater productivity
  • We suggest you should use it for:

  • Intended for metal, plastic, paint spot repair, automotive power train components and/or roll superfinishing
