How should I go about cutting a 2 inch diameter disk out of a bottle?
I had thought to use a diamond blade on my Ziptool to cut out a
rectangle and then wet grind the removed piece.

A diamond hole saw may be a possibility, but they are EXPENSIVE.

What would you suggest?

Thanks, Eric

As an aside, who would WANT a bottle with a hole in it (aside from the
obvious one)?
