Alpha-Mill

  • Various applications are available with multi-functional cutters.
Features
  • Innovative curve cutting edge and chip-breaker design ensures ideal 90 degree cutting and lower cutting resistance
  • Various applications are available with multi-functional cutters. (Facing, Slotting, Square shoulder milling and etc.)
  • Improved insert life time with optimized with each application.
  • Excellent perfomance ensured at large depth of cut operations due to strong cutting edge and low cutting resistance.
Alpha-mill Insert
  • Long tool life at high speed high feed and
    deeper cutting by low cutting
    resistance and strong cutting edge
  • Distinguished features of Alpha-Curve reduce
    cutting resistance and improve cutting edge
    strength and wear resistance
  • Low cutting resistance is realized by
    KORLOY unique design i.e alpha curve
    cutting edge and optimal convex and concave design
  • Highly efficient machining is
    available by the ideal application of
    the grade to material
Application example
