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 with a higher flute angle to remove chips more easily.
