I think what he's getting at is instead of drilling/milling away all the stuff in the very centre, just go around the edges. Leave a couple gaps not milled away (maybe opposite each other) to hold the centre chunk in place until the very end, then nip it out. You'd end up with a squarish shaped puck as waste, not everything in chips.
