  KC5010

  Composition: An advanced PVD AlTiN coating over a very deformation-resistant unalloyed carbide substrate. The new and improved coating enables speeds to be increased by 50–100%.
  Application: The KC5010 grade is ideal for finishing to general machining of most workpiece materials at higher speeds. Excellent for machining most steels, stainless steels, cast irons, non-ferrous materials, and super alloys under stable conditions. It also performs well machining hardened and short chipping materials.

• 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.

  KC810

• KC850

  composition: A CVD tri-phase coating on an extra-strong, cobalt-enriched
  alloyed substrate.
  application: Designed for heavy cutting of low-, medium-, and high-carbon
  steels, medium hardness alloy and tool steels, stainless steels, and some
  high-temperature alloys. Excellent thermal and mechanical shock resistance
  makes grade KC850 ideally suited for difficult drilling applications.
  Used in inserts for Kendex/Metcut drill bodies.
  

• KC9025
• KC910
• 
  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.

• KD100

  composition: A polycrystalline diamond tip (PCD) brazed onto a
  carbide substrate.
  application: The KD100 grade is for general purpose turning. The
  cutting tool material contains a binder in addition to diamond
  particles. This makes the KD100 grade suitable for roughing to
  finishing all types of highly abrasive workpieces, including non-ferrous
  metals and non-metallics. Use as your first choice on high content
  silicon aluminum alloys (hypereutectic). Will generally produce good
  surface finishes. Provides the best mechanical shock resistance of the
  diamond tool materials. The cutting edge is sharp. This grade operates
  at very high speeds.
  

• KD120

  composition: A high CBN content, PCBN tip brazed onto a carbide insert.
  application: The primary application area for high CBN content grades
  is in roughing to finishing of fully pearlitic gray cast iron, chilled irons,
  high chrome alloys steels, sintered powdered metals, and heavy cuts in
  hardened steels (>45 HRC). Also use for finishing chilled cast iron and
  fully pearlitic cast iron. Do not apply on finishing cuts in hardened
  steels. Available in regular size tips.

  KT315

  Composition: A multilayer PVD-TiN/TiCN/TiN-coated cermet turning grade.
  Application: Ideal for high-speed finishing to medium machining of most carbon and alloy steels and stainless steels. Performs very well in cast and ductile iron applications, too. Provides long and consistent tool life and will produce excellent workpiece finishes.
