I have used HSS, HSS TiN coated and Carbides, and Carbides have outdone all the above 10 times+. You will want 2 flute to cut copper, It has a higher chip capasity and less chance of clogging up.

I know blade uses HSS because he cannot find any carbide end mills, but he sure hasta be going through them fast. I know I do.
