Definately take less, If its still fast, like liquidrules said, decrease the amount your cutting.

What kind of mill are you using?

those end mills rule! thats what I use, they have lasted me a LONG time.

Get some cutting oil, or just some 5w 30 motor oil, Keep the end mill wet.

I like to take the first pass dry if Im not 100% sure on stuff. make it like .03" then I fill in the channels with oil, and keep adding more.

Definately keep your rpm as high as they can go. Ill soon be running my mill at 7500rpm
