Notes:

  • In milling aluminium and copper alloys:
    1. For improved surface finish, use together with wiper insert SEGW12X4ZEFR-WD
    2. For reducing burr occurrence, use together with deburring inserts SEGW12X4ZEFR-BD
  • When milling aluminium and copper alloys, use of a water soluble cutting fluid is recommended. When milling steels, cast irons, and stainless steels, dry cutting is recommended.
  • When the length-to-diameter overhang ratio of the tool (L/D) exceeds 3, reduce cutting speed and feed to 70 to 80% of the values given in the table.
