Achieve Close-Tolerance Finishes
We designed our 3M™ Microfinishing Film Belt 268L to enable operators to achieve precise, controlled, close-tolerance finishes. This product features precision, micron-graded aluminum oxide, resin-bonded to a high-strength, resilient polyester film backing. Aluminum oxide is desirable among industrial professionals for its fast cut-rate and long life.
Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.
Run Wet or Dry
These film-backed belts are water resistant, so they can be run wet or dry. Coolant generally extends abrasive life, increases cut rate and prevents loading. The high- strength, bare-film backing maintains its strength and flexibility when paper will degrade when run wet. This belt is commonly used for finishing automotive components.
