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-FIREX is a micro-layered coating that combines the characteristics and universal applicability of TiN, the heat resistance of TiAlN and the shock resistance of TiCN. The nano-FIREX structure increases overall thickness and shock resistance when compared to FIREX . FIREX is a proprietary coating exclusive to Guhring, Inc.
Spiral flutes are constructed with a higher flute angle to remove chips more easily.
