What is titanium nitride?
Titanium Aluminum Nitride (TiAlN): The titanium aluminium nitride coating can withstand temperatures up to 800°C (1450°F). At high temperatures, a layer of aluminum oxide is formed and it reflects the heat back onto the drill chips. This allows you to utilize higher cutting speed and feed and increased productivity.
