Before I built a CNC PCB Mill I used to drill boards by hand. At first I used a Dremel, then I found a cheap small $29 Chinese drill press. But I still broke bits all the time and my holes were far from perfect.
With the CNC Mill I simply position the board and hit Cycle Start. Whenever the routine needs a different size drill it shuts down, parks and tell me what drill to install. It is a dream.
