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.
FIREX is a multi-layer coating that combines the characteristics of universal applicability of TiN, the heat resistance of TiAlN and the shock resistance of TiCN. FIREX is a proprietary coating exclusive to Guhring, Inc.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
