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.
Titanium Aluminum Nitride (TiAlN) has a higher hardness and oxidation temperature versus TiN and TiCN. As a result, it is particularly advantageous for higher speed operations in a variety of steel machining applications.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
