■ Characteristics

  • Achieves efficiency through high speed, high feeding ability!! (v = 50 to 500m/min, f = 0.4 to 1.2mm/rev) c
  • Compatibility with a wide range of cutting conditions allows less strict cutting conditions and coolant control
  • Minimal cut edge length design eliminates biting and tearing for improved quality and reliability
  • Adoption of indexable cutting edge design improves reliability of quality and tool life, eliminating variability in tool life among reground inserts.
  • Cut edge diameters available from ø11.9 to ø140.6 mm
  • Easy insert replacement
  • Flexible tool overhang lengths possible by combining the modular extension arbor and shank with insert run-out adjustment mechanism
