Drilling in a lathe is different because the chips don't spin with the drill as readily, and break off due to centifugal forces. Thus they can get quite long.
Spade drill geometry seems ideal for chip breaking even stringy materials (which 12L14 isn't). With a through coolant spade drill body, you can readily get coolant to the tip and safely drill non-stop.
Haas mills have a variety of high speed drilling cycles (G73). These permit just about any sort of multi-chip break scheme with intermittent withdrawals that you can dream up. Not sure if the same cycles are available on a lathe. Of course, we don't know if this is a Haas lathe we are talking about here.
First you get good, then you get fast. Then grouchiness sets in.
