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.
Titanium Nitride (TiN) is a multi-purpose coating which increases chip flow in softer materials. The heat and hardness resistance allows the tool to run at higher speeds than uncoated tools.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
