Grades

• 
  K20K

  Coated carbide. MTCVD — TiN-TiCN-Al2O3-TiN. Great when used for straight or lightly interrupted cut applications of ductile and cast irons.

  K Cast Iron
• KB9640

  composition: A high CBN content, solid PCBN structure having multiple
  cutting edges and a CVD alumina coating.
  application: The KB9640 grade is applied in the roughing to semifinishing
  of fully pearlitic gray cast iron, chilled irons, high-chrome alloy
  steels, sintered powdered metals, and heavy cuts in hardened steels
  (>45 HRC). Also use for finished chilled cast iron and fully pearlitic cast
  iron. Do not apply on finishing hardened steels. The solid KB9640 also
  can be effectively applied when roughing hardened steels.
  

• 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.

• KC9120
• KC9315

  CVD-TiN-TiON-AL2O3-TiN coated carbide
  Extremely wear resistant for cutting cast iron materials
  Particularly efficient in the upper cutting speed range
  

• 
  KC9320

  Composition: A proprietary specially toughened MTCVD-TICN and AI2O3 coating over a wear-resistant substrate.
  Application: KC9320 is specifically engineered to maximise coating adhesion and edge strength making this grade ideal in wet interrupted cutting of ductile and gray irons. It can be in a wide range of applications from finishing to roughing to maximise productivity wherever strength and reliability are needed.

• KC9325

  CVD-TiCN-Al2O3 coated carbide
  Wear resistant grade
  For boring grey cast iron and ducticle cast iron
  For steel and dry machining applications
  

• KC990
• 
  KCK05

  Composition: A multilayered coating with moderately thick MTCVD TiCN-Al2O3 layers over a highly deformation-resistant carbide substrate.
  Application: Designed for high-speed machining of grey and ductile irons. The substrate and coating architecture together with CW5 post-coat treatment ensure a tremendous tool life advantage, especially when cutting higher tensile strength ductile and grey irons where workpiece size consistency and reliability of tool life are critical. Excellent both in straight and varied depths of cut.

  K Cast Iron
• 
  KCK15

  Coated carbide grade with CVD multilayer coating (TiN/MT TiCN/Al2O3) and advanced Beyond™ post-coat treatment. KCK15 is a wear-resistant grade with balanced toughness for general milling of cast irons at higher speeds. Best results in dry, but can also be used wet.

  K Cast Iron
• 
  KCK15B

  Composition: A multilayered coating with thick MTCVD TiCN-Al2O3-TiOCN layers applied over a carbide substrate specifically engineered for cast irons.

  Application: Delivers consistent performance in high-speed machining of gray and ductile irons. The substrate design permits the insert to stay in the cut for a long time at high speeds with minimum deformation. The thick CVD coating and post-coat treatment provide superior wear resistance ensuring long and consistent tool life. Can be applied both in straight and lightly interrupted cuts.

  KCK20

  A new PVD multilayer AlTiN + AlCrN coated carbide with an excellent combination of wear resistance and coating strength. The KCK20 grade is specifically engineered to maximize coating adhesion and edge strength, making this grade ideal in wet interrupted cutting of gray and ductile irons, and can also be used in dry conditions. It can be used in a wide range of applications, from finishing to roughing, to maximize productivity wherever strength and reliability are needed.

  K Cast Iron
• KY1320

  composition: An uncoated, advanced, silicon nitride grade
  application: High-speed roughing to finishing of gray cast iron.
  The KY1320 grade, with better wear resistance, is an ideal compliment to
  the KY3500 grade.
  

• 
  KY3500

  A ceramic cutting material based on micro-grain Si3N4 primarily for use in light to general machining of gray cast iron and ferritic ductile cast iron. Dry machining is recommended.
