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

Composition: With a multilayered PVD TiN-TiAlN coating and a high-quality P submicron carbide substrate, this grade gives a high level of wear resistance at M medium to high cutting speeds.

Application: First choice for high reliability in most materials. This grade should be K 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. P

Composition: With an advanced CVD TiCN-Al2O3 coating combined with a cobaltenriched carbide substrate, this grade offers a balanced combination of deformation resistance and edge toughness. K

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.

P

Composition: Advanced CVD TiCN-Al2O3 coating together with a newly engineered tough carbide substrate. Ensures adequate deformation resistance and excellent M 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 excellent reliability in steels, stainless steels, and cast iron rates.

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.

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 hightoughness applications. It covers steel, stainless steel, cast iron, and high-temp alloys under certain conditions.
