In fairness I just added the links for that exact product offering from Niagara to my post above. So you probably didn't see that when you posted this.

Not exactly the most reputable site. Find any cutting tool company that recommends TiAlN for aluminum. Find any cutting tool company that sells aluminum specific geometry, and see what coating they put on the tool. It's not TiAlN.

Again look up at the end of my last post. Niagara sells those bits with TiAlN coating specifically for aluminum. So let's not so hastily assume that the coating company I linked is also self-promoting.

Here:

Niagara Cutter 86002 Carbide Square Nose End Mill, Inch, TiAlN Finish, Roughing and Finishing Cut, 30 Degree Helix, 3 Flutes, 1.5" Overall Length, 0.125" Cutting Diameter, 0.125" Shank Diameter

The end mill above led me to the end mill below...

Niagara Cutter A245 Carbide End Mill for Aluminum, TiAlN Coated, 2 Flutes, Square End, 4-1/8" Cutting Length, 1" Cutting Diameter

Which gave me a reference to search for this...
