Nice Catch...
Back in the day before people had hair I did quite a bit of custom car model
building and I had a set of those very drill-bits. The bad news is they only
went up to about 11/64ths and they had a 1/8 shank.
I think I bought mine from a hobby and craft shop.

I remember a bit some time back that began with a normal drilling tip but
further up the bit it had small teeth and one was supposed to be able to
then move it sideways and these teeth which were from memory half file-like
and half small saw-tooth like, would work like a saw.  I know my memory
alone isn't much to go on here, but perhaps others have seen a similar bit.

  Thanks all for your input. I don't have many holes and am famously hard on
  drill and router bits so think I'll try the file.

  Ralph,
  Drill the hole at one end of the prospective slot, get a rat tail file
just
  a bit
  smaller than the hole and grind away.

  You might try drilling and pushing sideways on the board, but you'll end
up
  breaking bits. You can get router bits pretty small but when they're
  that small, assuming big enough for a number 4 screw or the like, the 
  surface speed of the bit gets pretty low and they're not efficient.

  A file's the way to go unless you've got lots of holes.
