I buy my HSS drills from Screwfix, they sell them in packs of 10. 1mm drills only cost £2.02 for a pack of 10, so I don't mind if they break on me. See;

I use a pendant drill and I lubricate the drill each time I drill, with either oil or if I want to keep the surface relatively clean I drill into a candle to lubricate it, I do this before each attempt at drilling, you cannot lubricate too much. I actually use standard white candle for saw blade lubrication also.
