Grades

KC7210

Composition: PVD TiAlN coated fine-grain carbide with enhanced hot hardness properties.
Application: Best suited for dry machining of cast iron. The enhanced hot hardness properties of the substrate combined with a wear-resistant TiAlN coating offer highest material removal rates using the triple fluted drill design.

P Steel

K Cast Iron

N Non-Ferrous
KC7215

Composition: PVD TiAlN coated fine-grain carbide.
Application: Best suited for machining of alloyed steel and cast iron. This grade offers reliable performance at intermediate cutting conditions.

P Steel

S High-Temp Alloys

K Cast Iron

M Stainless Steel
KCPK10

Composition: Advanced CVD TiCN-Al2O3 coating combined with a cobalt-enriched carbide substrate.
Application: The KCPK10 grade offers a balanced combination of deformation resistance and edge toughness leading to outstanding abrasion and crater wear resistance for high-speed machining of steel and cast iron. Use for very high cutting speeds with low to medium feed rates.

K Cast Iron
KCU25

Composition: An advanced PVD grade with hard AlTiN coating and fine-grain unalloyed substrate. The new and improved coating improves edge stability with wide range speed and feed capabilities.
Application: The KCU25™ grade is ideal for general machining of most steels, stainless steels, high-temp alloys, titanium, irons, and non-ferrous materials in a wide range of speeds and feeds with improved edge toughness for interrupted cuts and high feed rates.

K Cast Iron
KCU40

Multilayered PVD TiN-TiAlN-coated fine-grain carbide, offering
highest wear resistance in steel, stainless steel, cast iron, and high-temp alloys.

K Cast Iron
KM1

Composition: Uncoated, fine grain, straight carbide grade, containing 6% cobalt.
Application: General purpose grade for use on gray iron, aluminum, and non-ferrous
work piece materials. Available for use with HTS-C deep drilling tools and CTR
countersinking tools.
