Features and Benefits

Solid carbide provides better rigidity than high speed steel. It is extremely heat resistant and used for high speed applications on cast iron, nonferrous materials, plastics and other tough-to-machine materials.

Aluminum chromium nitride (AlCrN) has higher heat resistance than AlTiN. It is commonly used for machining aircraft and aerospace material, nickel alloy, stainless steel, titanium, cast iron and carbon steel.
