Grades

• KC8050

  composition: A newly developed, advanced cobalt-enriched carbide
  grade with a thick alumina coating.
  application: A versatile performer on a wide range of workpiece
  materials (steels, stainless steels, and cast irons) for roughing through
  finishing operations. This highly wear-resistant grade can operate with
  or without coolant at high speeds, and has exceptional edge strength
  for interrupted cuts. The micro-finished insert edge resists workpiece
  build-up and microchipping, and produces excellent surface finishes.
  For machining steels and cast irons, your first choices are the -RN and
  -MN geometries. For medium machining applications and finishing
  cuts, the -MP and -FP geometries with a positive rake are suggested.
  

• KC9010
• KC9025
• KC9105

  composition: An innovative, highly deformation-resistant cobaltenriched
  substrate (patent pending) with a new thick multilayer
  MTCVD-TiCN-Al2O3-TiCN-TiN coating for maximum wear resistance.
  application: KC9105 is the latest addition to the KENNA PERFECT
  grades for finishing to medium machining of most steels, ferritic,
  martensitic, and PH stainless steels and cast irons The specially
  designed substrate provides a remarkable combination of deformation
  resistance and insert edge strength. The extra-thick MT-TiCN layer
  provides outstanding flank wear resistance, while the thick Al2O3
  layer offers excellent crater wear resistance and speed capability.
  A state-of-the-art post-coating treatment results in a smooth insert
  surface that reduces microchipping and build-up and improves
  workpiece surface finish.

  KC9110

  Composition: Specially engineered, cobalt-enriched carbide grade with thick K-MTCVD-TiCN coating layer, an Al2O3 layer of controlled grain size, and outer layers of TiCN and TiN for maximum abrasion and wear resistance for high-speed machining.
  Application: An excellent finishing to medium machining grade for a variety of workpiece materials including most steels, ferritic and martensitic stainless steels, and cast irons. A balanced combination of deformation resistance and edge toughness. The smooth coating resists built-up edge and microchipping. For rougher cutting, use the KC9125 grade.

• 
  KC9125

  Composition: A tough cobalt-enriched carbide grade with a newly designed multilayer K-MTCVD TiCNAl2O3-TiCN-TiN coating with superior interlayer adhesion.
  Application: General-purpose turning grade for most steels and ferritic and martensitic stainless steels. The substrate design ensures adequate deformation resistance along with excellent bulk toughness and insert edge strength. Coating layers offer wear resistance over a wide range of machining conditions and reduce frictional heat, minimise microchipping, and improve workpiece surface finishes. Performs well in moderately heavy roughing to semi-finishing cuts. Use the KC9110 grade for finishing cuts.

• KC9140

  composition. A newly engineered, tough carbide grade with an advance multi-layered TiN-MT-TiCN-Al203-TiN coating.
  Application. For heavy roughing applications of alloy steels where insert edge strength is critical. A specially designed coating ensures excellent interlayer adhesion and long tool length.
