KC520M
Coated carbide grade with TiAlN coating (PVD). KC520M is a carbide grade developed specifically for general machining of ductile cast iron. This grade can be used with or without coolant.
K Cast Iron -
KC522M
Coated carbide grade with a AlTiN (PVD) coating. KC522M is engineered to provide better performance in general machining of high-temperature alloys and stainless steel. KC522M resists breakage and offers improved wear resistance and increased strength.
P SteelS High-Temp AlloysH Hardened MaterialsK Cast IronM Stainless Steel -
KC725M
Coated carbide grade with an advanced PVD TiAlN coating. KC725M is a high-performance grade for milling steel, stainless steel, and ductile cast iron. The good thermal shock resistance of the substrate makes this grade ideal for both wet and dry machining. Primarily for use in general and heavy machining.
P SteelS High-Temp AlloysM Stainless Steel -
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 -
KCK20B
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 grey 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.K Cast Iron -
KCPK30
Coated carbide grade with CVD multilayer (TiN/TiCN/Al2O3) and advanced Beyond™ post-coat treatment. Substrate is very tough. KCPK30 has a wide application area in general and roughing milling of steels and cast irons. Performs best dry, but can also be used wet.
P SteelS High-Temp AlloysK Cast IronM Stainless Steel -
KCPM20
Coated carbide grade with CVD multilayer (TiN/MT TiCN/Al2O3) and advanced Beyond™ post-coat treatment. Substrate is a well-balanced combination of wear resistance and toughness. It is primarily for light and general machining of steel and stainless steel roughing of cast irons.
P SteelH Hardened MaterialsK Cast IronM Stainless Steel -
KCPM40
Coated carbide grade with an advanced PVD TiAlN/AlCrN coating. Tough substrate with excellent capability at higher temperatures. KCPM40™ is the first choice for milling steel and stainless steel. Good thermal shock resistance makes this grade ideal for both wet and dry machining. Primarily for use in general and heavy machining.
