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.
nano-Si coatings are made of Titanium Aluminum Silicon Nitride (TiAlSiN) and are similar in performance to Diamond-Like Coatings (DLC). It is also similar to FIREX or TiALlN. nano-Si is a proprietary coating exclusive to Guhring, Inc.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
