Features and Benefits
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
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.
