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 one of the hardest of the nano coatings and used in aerospace, medical and energy industries. nano-Si is a proprietary coating exclusive to Guhring, Inc.
Spiral flutes are constructed with a higher flute angle to remove chips more easily.
