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.

• 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.
