What tool and process should I use to make these 2 cuts?
If I use a standard end mill won't the edges be a bit round?
I am assuming that for the hex one I drill the hole first and then endmill the sides with a normal size tool and then pick a small tool to make the edges square?
And for the square one I just end mill everything and then make the edges square with a smaller end mill.
Are these the normal processes for doing this type of work?
Cutting into 6061 aluminum if it matters
