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.
Uncoated tools do not feature supportive treatments on the cutting edge. They are are used at reduced speeds for general applications on non-ferrous metals.
