Re: Drilling speeds and feeds for 6063
For a drill your feed numbers seem quite slow (did my calc give those numbers to you? edit: never mind, i see you are using feed override).
BUT considering this is just an endmill with a pointy tip, i think it will work out ok.
BUT i hope you have coolant and you peck often to prevent chips from clogging.
Because it is not a real drill, you will not have proper chip clearance. Especially for deep holes.
And that 0.5" deep hole seems like it might cause you trouble unless you peck.
This can also be done dry. But for that you will have to go really slow RPM -wise. IMO it is easier to drill steel dry than aluminum.
