I use a full carbide 1/4" spiral bit @ 15000 RPM 12 IPM with 0.025 pass depth. I use wd40 or windex. Although a lot of people like to cut dry, tool life is extended with coolant. Its slow, but boy what a great cut.

I first tried to use my milling machine HSS TiN 2 flute spiral bits. Good in the milling machine, but crap in the router.

Others told me to look at Belin Yvon cutters - specific for aluminum routing. I ordered a few they are fantastic.
