I have used the Dremel Drill Press both the older version and the newer Version, when I do boards I maybe drilling 4000+ holes. Really need to get my CNC project going but that keeps getting put off. Normally if I break a bit it is because I failed to hold the board good or tried to move the board before the bit cleared the board. Don't really seem to have a problem with runout breaking the bits. No Dremel tools are not the best, and the drill press not the best either but does work well for drilling PCB's. I use .7mm (.0280") bits - 2mm (.0787") bits I might break 1 bit during a run of borads, guess 1 bit in 4000+ holes is not too bad, and that is normally due to getting in a hurry.

Get yourself a couple of good lights to light the work area from each side and a vac nozzle mounted to suck up the dust with a shop vac. Mount the base of the drill press to your bench or a piece of plywood and some pads for your elbows to rest on.

So if you already have a Dremel go ahead and get the Dremel Drill Press.
