I just received my order of 1/32" tungsten carbide drill bits with 1/8" shank. The 1/32" size is very good for drilling general purpose holes in PCBs. I simply used a Dremel and drilled the holes by hand. The tough part is centering the drill bit on the hole (on the copper side), but once you have it centered, the drill goes through very quickly. I didn't have any trouble with drilling and did not snap any bits.
