Common Coatings for Tungsten Carbide End Mill

On the market today , for tungsten carbide end mill, the well accepted common coatings comprise Titanium Nitride (TiN), Titanium Carbon Nitride( TiCN) and Aluminum Titanium Nitride (AlTiN) , as well as Titanium Aluminum Nitride (TiAlN).

Since the coatings like AlTiN and TiSAlN have extra aluminum content,which are more effective at evacuating heat, they are more popular in end mill applications. Specially ,both TiAlN and AlTiN is a thin film coating that was delveloped from Titanium Nitride. It is recommended that when machining aluminum, brass, plastics and other nonferrous materials it is better to use AlTiN or TiAlN coated end mill with polished flutes to prevent edge buildup.
