Re the cork borer. That may be do the job. I remembered those from way
back and indicated earlier in this thread that a I would probably be
looking at a homemade version. Don't recall a 1" size in the sets I used.
Do you know of a source? I've since tried the reversed hole saw that was
suggested, but lubricated or not it tore up the foam. I need a smooth
inside wall. The sharp edge like on the borer might do it. It'll need a
gentle touch.

Probably your best bet would be a "cork Borer" which is a set of hollow
tubes with a handle at one end and the bottom of the thin wall tube is
sharpened. You press down and rotate the tube with the handle to cut out a
plug.

Actually I'm using a kid's 4oz practice hockey puck as the blank. It's
1" thick and I need to make a 1" hole in it's center. Does anyone know
of type of bit or other type of cutter that would make a clean cut. The
common bits and step bits just rip it up.
