You drill the entry hole as you would for a boring bar first Mike, then go in with the end mill using only one flute. I've done this several times on tough material like stainless using carbide end mills. They seam to be less prone to chatter as well.
Along the same line, you can grind away three of the four flutes of a tap, then grind away all but the first couple of teeth then use it for single point threading and get full form threads.

Free advice is worth exactly what you payed for it.
