- High speed steel (HSS) provides good wear-resistance
- 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
- Parabolic flutes are constructed with a wider flute shape for increased chip flow
- Web-thinned
- Tapered web configuration
- No coolant channel
