You can get end mills as small as .010 (IIRC), typically 2 flute, solid carbide. My usual source for these is ebay, however wholesale tools (www.wttool.com) as well as enco (www.use-enco.com) have them when I'm getting low and need one right away, look for carbide end mills. I must warn you to be sitting down, they're not cheap.
