Grade Description
05 10 15 20 25 30 35 40 45
Coating 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.

TiCN-Al2O3
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 very good reliability in steels, stainless steels,
and cast iron 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.
