[sdiy] pcb drilling

[Chris CROSSKEY]

I use a small (smaller than a dremel) power drill that is designed for 
high-speed low torque stuff, it's one of the Minicraft range but I couldn't 
tell you which one off the top of my head..... get the drill press for it 
though as you can break a lot of drills otherwise. Buy reground drills, they 
are way sharper than new adn just as good, just no longer suitable for CNC 
people.....0.85mm covers most normal stuff and a few bigger ones for things 
like TO220 transistors etc.........
