Features and Benefits
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
Aluminum chromium nitride (AlCrN) has higher-heat resistance than AlTiN. It is commonly used for machining aircraft and aerospace materials, nickel alloys, stainless steel, titanium, cast iron and carbon steel.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
