End Mill Coatings
·The use of coatings will increase the surface hardness of the tool. This will allow for greater tool life and faster cutting speed.
·Standard coatings include Titanium Nitride (TiN), Titanium Carbonitride (TiCN), and Aluminum Titanium Nitride (AlTiN).
·Long-life TiN (titanium nitride) coating is good for use on alloy steel, aluminum, and plastic. Color is gold.
·Extra-life TiCN (titanium carbonitride) coating has better wear resistance than TiN coating, making it a good choice for tough-to-machine materials such as ductile cast iron, stainless steel, aluminum, and plastic. Color is blue-gray.
·Super-life AlTiN (aluminum titanium nitride) coating is the best for very high feeds/speeds and high-temperature applications. Use to mill cast iron, stainless steel, nickel-based alloys, and titanium. Not for use on aluminum. Color is purple-gray.
·The choice to use coated end mills is a cost versus benefit choice. If your machining benefits enough from the extra performance of a premium coating, purchase end mills with a coating.
