The last time I did a successful PCB, the drill hole size relative to the component pad size is rather huge to the point where when I entered the soldering stage, the component wires were not connecting to the pads correctly.
What I want to do in eagle is change the drill holes on every device (with small pins) on my PCB so that they are about 1/64ths of an inch instead of Eagle's preferred size, that way, when I drill, I drill a small amount of copper but at the same time, the copper will meet with the hole and the odds of a strong connection are higher.
Is there a quick way I can make the drill holes smaller in eagle without having to manually edit each part one-by-one?

There is an User Language Program (ULP) for this, in the standard distribution. It is called
drill-aid.ulp.You run it on your finished PCB, before printing. it will make all the drilled pads smaller, making it easier to drill manually. As a side effect, you will get the requested function.
It will generate the extra copper in a separate layer, so that it can be removed and re-generated if you modify the board.
