Beeswax is a good lubricant for the smaller sizes down to number 80.

I buy the micro drills off ebay, the ones with the larger shank, usually with a size coded color ring.  They say used but all the ones I've bought have been sharp.  I've never had one break in plastic.  The only time I break one is in a resin part, even with lubrication.  I've bought multi size sets, but now buy the bulk sets of the size I break the most.
