Grade Description
Composition: With a multilayered PVD TiN-TiAlN coating and a high-quality
submicron carbide substrate, this grade gives a high level of wear resistance at
medium to high cutting speeds.
Application: First choice for high reliability in most materials. This grade should be
used at medium to high speeds and feeds. It is a general purpose grade that performs
very well for alloyed and high-alloy steel and cast iron, but can also be used with
excellent performance in stainless steels.

NOTE: Previously named K20FTiAlN.
Composition: Advanced CVD TiCN-Al2O3 coating together with a newly engineered
tough carbide substrate. Ensures adequate deformation resistance and excellent
edge strength and offers very good wear resistance over a wide range of
machining conditions.
Application: A high productivity grade with high speeds and feeds. First choice
for high productivity with excellent reliability in steels, stainless steels,
and cast iron rates.
P
Composition: With an advanced CVD TiCN-Al2O3 coating combined with a cobalt-
enriched carbide substrate, this grade offers a balanced combination of deformation
resistance and edge toughness.
Application: Offers outstanding abrasion and crater wear resistance for high-speed
machining of steels and cast irons. Use for very high cutting speeds with low to
medium feed rates.

Composition: With a multilayered PVD TiN-TiAlN coating and a tough substrate,
this grade withstands interruptions and provides high wear resistance for long tool life.
Application: First choice for high reliability in most materials. This grade should be
used at medium speeds and high feeds due to sharper edges and as a grade for high-
toughness applications. It covers steel, stainless steel, cast iron, and high-temp alloys
under certain conditions.
