Item #: 87800660Brand: GuhringModel #: 9012430111100 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 with a higher flute angle to remove chips more easily.
