P
An advanced PVD TiAlN coating over a very deformation-resistant unalloyed carbide M
TN6010 materials at higher speeds. Excellent for machining most steels, stainless steels, cast K
substrate. TN6010 is ideal for fi nishing to general machining of most workpiece
N
irons, non-ferrous materials, and super alloys under stable conditions. It also performs
well machining hardened and short chipping materials.

M
An advanced PVD TiAlN-coated grade with a tough, ultra-fi ne-grain unalloyed
Grade TN6025 substrate. For general-purpose machining of most steels, stainless steels, high-temp K
alloys, titanium, irons, and non-ferrous materials. Speeds may vary from low
to medium and will handle interruptions and high feed rates. N
S
HC-P25

Uncoated carbide for light and medium machining. For cast iron, all non-ferrous K
THM metals, and non-metals. Also capable of machining hardened materials at low
cutting speeds. N
