There are two tools needed here, one is a track cutter for strip board
http://uk.farnell.com/pcb-track%c2%a0 and the other is a pad cutter
http://www.vectorelect.com/Catpdf/New%20Page%2076.pdf for Vectorboard
The pad cutter is very pricy and is available for manual and drill press operation.

I've seen boards built with this. Usually the pre-drilled proto board, but
with copper tracks that run from one edge to the other, and you separate
the rows into smaller sections with the little hole saw, but I've never
seen the tool. Have any info on it?
