a set of cork borers

(well more technically, borers for rubber stoppers)

Not that long ago (when I was a grad student), one used to actually make some of one's own lab apparatus, and every lab had a nice, sharp set of "cork borers" to put holes in rubber stoppers for glass tubing etc.

I have to assume that the supply houses still have these...

Try someone like Daigger (link below). AFAIK, they'll take a personal CC; I bought a replacement glass blender head for a vintage Waring blendor from them some years back.
all the best,
