Homebrew PCBs

Does anyone have any suggestions where I can obtain a set of pad 
cutters.  Would like to be able to cut various size pads on my PCBs.  
One common use will be to isolate pads on the back side of the PCB
for the occasional thru-hole lead components I use.

dunno where they are sold, you can grind one.
Take a broken drill, grind the end flat to maybe 2mm or so, and grind out  
a center pin and cutting points on the sides, like a old fashioned wood  
drill without the cutting face on the front. Round that off so you don't  
drill the pad away if you don't set the stop correctly.

I've also seen people use small tubes, and file teeth on them.

Farnell stocks them. Only one size, though.
