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.
Multilayer Titanium Carbonitride (TiCN) is harder and more wear resistant than Titanium Nitride (TiN). It is used on a variety of materials including stainless steel, cast iron and aluminum alloy
Spiral flutes are constructed with a higher flute angle to remove chips more easily.
