In the past I used a vector pad cutter (a great tool for doing
breadballs) to cut the traces on Vero/Vector boards. The cutter has a
guide pin to guide an annular cutter. Generally used to isolate a pad
on a blank PC board, but works great for cutting the traces on
protoboard. Since it is a mill-like cutter, it does not generate a
divit like a drill bit.
A while back after being deprived of access to this tool (read
downsized...), I decided to pick one up for myself. The part is listed
in Digi-key under the Vector Board section. However, the sticker shock
was extreme. As an alternate, I found that they make mills of similar
design for cutting various sizes of o-ring grooves and are priced
within reach.
As a cheap alternate, a simple end mill of the right diameter in a
drill press should do the job admirably.
