What size drill bit for PCB?
So, you want at least two 0.8mm drill bits in your rack since small bits tend to be brittle and break easily. 1.0mm and more significant bits are more resilient, but you should always have at least one spare just in case. You also want to make sure your holes are about 0.007 mm larger than your leads.
