- Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems
- Titanium aluminum nitride coatings become self-lubricating when used at very high speeds, making them ideal for cutting without coolant ("dry machining")
- Round shanks allow use with a wide variety of toolholding systems
- Through-hole flute style has a single flute that passes through the cutting head to reduce vibration and chip clogging; also called "zero flute"
- For centering and countersinking on NC and CNC machines
