Features and Benefits

Powdered Metal (PM) is tougher and more cost effective than solid carbide. It is commonly used on highly abrasive materials including high silicon aluminums.
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.
Parabolic flutes have a wider flute shape for increased chip flow.
