Well I talked to the tool guy at my local hardware store who directed me towards something called a PIN VISE. Its just like a screwdriver with a little chuck in it for holding drill bits. I bought it, and one bit of the right size (forget what I determined proper vero-cutting size to be) which I leave clamped in the pin vise. Now I have a little hand tool which is always out on my bench and that makes trace cuts in vero with only about 4 or 5 twists of my wrist.

maybe this is old knowledge around here, but i found it to be tremendously useful.
