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, non ferrous materials, plastics, and other tough-to-machine materials.
Aluminum chromium nitride (AlCrN) and titanium silicon nitride (TISIN) is a multi-layered coating that is extremely wear resistant. It is commonly used for machining aircraft and aerospace material.
