Hi Chuck,
I use carbide bits, something around 0.029 for most things, 0.035
for header posts and 0.041 for TO-220 and trimmers.
You should use a drill press with minimal runout if you don't have a
steady hand. I drilled hundreds of holes with a hand held Dremel
tool before I bought a stand. Wear eye protection and be mindful of
dust.
I bought on eBay and from Harbor Freight.
Regards,
Dennis
