Homebrew PCBs

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
