P
Composition: With a multilayered PVD TiN-TiAlN coating and a high-quality submicron
M
carbide substrate, this grade gives a high level of wear resistance at medium to high
WU25PD cutting speeds. K
Application: First choice for high reliability in all materials. This grade should be used
N
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 S
performance in all other material groups.
H
P
Composition: With a multilayered PVD TiN-TiAlN coating, a high-quality submicron
WP20PD carbide substrate and a state-of-the-art surface condition, this grade gives the highest K
level of wear resistance at high cutting speeds.
Application: A high productivity grade for high speeds and feeds. First choice for high
productivity with excellent reliability in alloyed and high-alloyed steels and cast irons.

Composition: With a newly developed unique multilayered PVD AlCrN coating and
Grade WK15PD a high-quality submicron carbide substrate, this grade gives the highest level of wear K
resistance at high cutting speeds.
Application: This grade offers extraordinary wear resistance in drilling of cast iron

materials. With its high hot hardness it allows for high speed machining.

P
Composition: With a multilayered PVD TiN-TiAlN coating, a high-quality submicron
WU20PD carbide substrate and a state-of-the-art surface condition, this grade gives the highest K
level of wear resistance at high cutting speeds.
Application: First choice for alloyed and high-alloyed steels and cast irons. A state-of-
the-art surface condition enables superior chip evacuation even when MQL is applied.

WN10HD Composition: This uncoated fi ne-grain carbide with high hardness offers excellent K
abrasive wear resistance.
N
Application: First choice for precision drilling of non-ferrous materials.
