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 Aluminum Chromium (AlCr) is a blended coating for high performance applications. It is extremely wear resistant and used in cast iron applications due to its high hot hardness
Spiral flutes are constructed with a higher flute angle to remove chips more easily.
