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 heat and wear resistant and used in cast iron applications due to its high hot hardness.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
