>>Like Mark says, a hand drill is ideal for this job.
While I agree with myself, I would call it a a power drill :)
I do have an actual hand drill that belonged to my father. It has
wooden handles and a crank on the side like an eggbeater. I use to
drill PCB's, as it can't accidently skip and destroy traces.
>>The paint won't chip, either. I make those holes smaller because

>>we can't drill them smaller : )
Indeed :)
>>Cool. I've never drilled through metal this thick before. Is it an

You want a variable-spped power drill with a large-enough chuck to
fit the bits you are using. When I had to drill a bunch of panels,
including some tricky stuff like the LED holes for a MiniWave, I
borrowed this massive professional drill press from my next door
neighbor. Which was much better than using a hand-held power drill,
but not necessary if you only have to drill a few holes.
Secure it from moving (you can use the mounting holes in the corners
of the panel to screw it to a board), drill from front of the panel
so that any damage to the paint is to the back side, and use a
lubricant such as cutting and tapping spray.
