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.
WXS is a nano-coating that yields higher hardness and oxidation temperature versus TiAlN. It is designed for maximum heat resistance in hardened steel over 50HRC and nickel-based alloy. WXS is a proprietary coating exclusive to OSG Tap and Die, Inc.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
