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 (PCD) coating is one of the hardest coatings. It is commonly used on concrete, fiberglass, plastic, stone, aluminum alloy and extremely difficult-to-machine materials.
Spiral flutes are constructed with a higher flute angle to remove chips more easily.
