Features and Benefits
High speed steel (HSS) provides good wear resistance and can be used in general purpose applications for both ferrous and nonferrous 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.
