Cutting Disks

I have two sizes of disk to cut, from two or three different materials:
Disk 1: 3/4" diameter, from 6mm thick "Depron" foam. *This is a
close-cell polystyrene foam (I think it's extruded).
Disk 2: 0.125" to 0.150" diameter, from 1/64" plywood or 0.015" styrene
(I have the plywood, the styrene matches the color and chemistry of the
foam).
Both need to have a .025" diameter hole drilled, but that's not the big
problem.
How many do you need to make? If it is not too many, I would try
making a single sided die and use it spinning in a drill press. It
could have a .025 drill so it drills the hole first and then cuts the
disk in one operation. Think of a toothless hole saw. I have used
something like this for cutting rubber disks. I did not need the
hole in the center.
