how to drill
It occuers to me that I need to know more than "put a drill shaped
thing on the metal, turn drill on, push".
Can anyone recommend a good site for information about drilling?
Things like what different bits there are and how to tell what you
have? What speeds for what metals, which drills for which applications,
what difference does torque setting make, when should you drill a
pilot hole?
