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.
Diamond (CVD) coated tools are the hardest of the coatings. It is used exclusively for applications in non-ferrous materials such as aluminum, graphite, copper, and carbon fiber.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
