 hold.  There's quite a good picture at

 Ah... I was under the impression that the cutting edge had a
 substantially different angle fro a drill (like describing a 180
 degree arc between the cutting surfaces rather than, say, 150
 degrees).

 I guess this picture...

 .... really shows the divot one gets from the real tool.

 I might just have to just use the drill press for this task (taking
 advantage of the stop to keep from drilling _though_ the resin board
 ;-)

 The tool looks handy for more than a few cuts, though.   I wouldn't
 want to try just holding a bit bare-handed - lots of hand cramps and
 slips probably.

  Thanks for the website tip... nice pix.

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.
