  • Item Features
  • T8330 grade sub-micron substrate with a relatively high cobalt content
  • Cutting geometry particularly suited to parting and grooving
  • Suitable for turning, with an indexing accuracy to ISO tolerance class-G and chipbreakers on one side only
  • FF2 chipbreaker - positive geometry with low cutting resistance
  • Improved cutting edge stability
  • Straight cutting edge
  • Very good chip control at low feed and depth of cut
  • High quality of surface finish
  • Increased performance and tool life in combination with the upgrade grades
  • Especially for small and slender components
  • Nano-layered PVD coating with gradient transitions
  • Lower internal coating tension with higher hardness
  • Lower notch wear on the main cutting edge
  • Medium cutting speeds
  • Good operative reliability
  • Impaired machining conditions
  • Extremely universal cutting geometry, generates a very low cutting force and has good stability
  • Suitable for slightly interrupted cut
