P
Composition: With an advanced CVD TiCN-Al O coating combined with
2 3
WPK10CH of deformation-resistance and edge toughness. K
a cobalt-enriched carbide substrate, this grade offers a balanced combination
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-Al O
2 3
P
Composition: Advanced CVD TiCN-Al O coating together with a newly engineered
2 3
tough carbide substrate. Ensures adequate deformation resistance and excellent M
Grade WU25CH edge strength and offers very good wear resistance over a wide range of K
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.
TiCN-Al O
2 3
P
Composition: With a multilayered PVD TiN-TiAlN coating and a tough substrate, M
this grade withstands interruptions and provides high wear resistance for long tool life.
WU40PH Application: First choice for high reliability in most materials. This grade should be K
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.
