Item #: 48420764Brand: KennametalModel #: 1913779 Features and Benefits Solid carbide provides better rigidity than high speed steel. It is extremely heat resistant and used for hi gh 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 with a higher flute angle to remove chips more easily.
