ExtraCut 20 2D (F8330)
6 Flute Square End

Features

  • Alternate Helix 20°/22°
  • Center Coolant Supply
  • Chamfer 45°
  • Eccentric Relief
  • Enhanced Core Size
  • Length of Cut 2xD
  • Minimized Flute Cross Section
  • Non center cutting
  • PVD Coated
  • Unequal Indexing
  • Weldon Flat

Application

  • Intended for operations where there is a risk of pulling the workpiece out of the vice during machining, or for an unstable thin-wall workpiece like a tube or sheet metal that can vibrate due to axial end mill force caused by its helical flute.
  • Machining of extremely tough materials or austenitic steels up to 600N/mm2 of ultimate tensile strength.

Annotation

  • Alternate helix dampens vibrations
  • Distribution of the tool wear to more edges enhances the tool life
  • These materials are characterized by poor machinability. Their machining requires a very sharp edge and smooth flute finish that prevents material build up.
  • Weldon Flat Guarantees the Torque Transfer and Prevents the Shank Extracting (microcreeping)
