100 degree countersink

[Bob Savage]

I may take a swing at cutting aluminum on my Camaster and need to put a couple 100 degree countersinks in the material. Any leads on what bits would be good for this using the cnc?

Severance Tool makes really good countersinks. Look at their chatterless countersinks. They are available in 100 degree.
