Note that using a boring head on the mill will not eliminate the
need for a hole to start with -- and the bigger the hole the better,
because a boring head is rather a rather slow way of removing material.
So, a hole saw to produce an undersized hole is a good thing to use
*with* the boring head.

Enjoy,

You missed the part about trepanning, DoN. I've done it with outstanding
success. You can, indeed, create large holes without having a starter hole.
That was the point of our discussion above.
