It's a matter of combatting the tendency to bind because of the gummy material combined with the abnormally high rate of expansion with increasing temperature. Coolant is obviously crucial, as noted by the first respondent.
You need higher than normal relief angle, bright finish not black, and (if you can) thin webs and narrow margin lands. Definitely go with slow speed and heavy feed regardless of drill geometry.
Another thing which helps if drilling from the tailstock of a manual lathe, where excessive backlash can present a problem with grabbing: slow-helix drills (ie straighter flutes than usual).
If you can't source such drills and have grabbing problems, it could be worth stoning an axial land (equivalent to zero top rake in the lathe tool analogy).
It doesn't have to be very wide to make an appreciable difference, but does need to be very smooth.
