Avogadro's Lab Supply on eBay has a good selection of cork borers.

Avogadro's supply used to have a big selection of glassware but this seller appears not to be on ebay, right now. . .
Edit: Correction, I just found AS by googling the name!

This company used to be called Hagenow Laboratories. I found their ads in the back of Pop Sci, and other magazines, IIRC, in the 1970's and ordered
things from them now and then since the 70's. They try to keep prices low.

Look on page 58 for cork borers. You'll need that sharpener, too. I haven't found anything else that can sharpen cork borers like the cork borer
sharpener can.

I had just recently used my cork borer from Avagadro this last week on a number 6 hard rubber stopper. Worked great with some muscle power . I have had them for 3 years and they are worth the high price I paid for them.

They have to be sharp to work good with rubber stoppers. They also come in handy as leather punches, which you might need for your belt as you age
and get fatter.

I recently read somewhere that if a rubber bung is placed in the freezer a neat hole can be then be drilled in it using a drill press (while still
cold). This is obviously not as elegant as a hole borer but might work OK in the home lab setting.

Tim, Probably not the sort of hole you could get a good seal with when using <10mm osd glass tube…

I've always hated using hand held borers.
Neoprene stoppers are awkwardly shaped. They are also very tough, rubbery, and hard to bore. The borer is very sharp.
If you haven't used cork borers before, watch out. When they slip off, or they "pop" through.....They can produce exquisitely painful wounds.
Just absentmindedly testing the tip of a really sharp borer, with a finger-tip, can cut you pretty good.
Naturally, the bigger the required hole, the greater the force required to bore it.
And, "large" holes are damn hard to produce. Nasty work!
Boring holes through frozen stoppers, with the aid of a drill press, sounds like a good idea to me. I'll try it.

Most of the textbooks I've seen recommend using glycerine as a lubricant. I find it to be lacking in its ability to lubricate.
Try some liquid soap mixed with water, you might be surprised at how well it works. It cuts through the rubber like butter.

I concur. The hardest part though is getting the glass tubing through the new hole! That definately calls for the Dawn dishwashing liquid! That
stuff is great! When water is warmer than 50C Dawn really picks up palm and coconut oils well considering the high saturated fat content!

And that's the story of how I put a glass tube right through my hand.

I saw a cork boring machine like the one in the picture in an antique store and on Ebay before. I never bought one, but I found one later on in a
dumpster at a university without the borers.

Avoiding shipping and payment was my point

Boring corks is serious chemistry! But I do love ground joints.
I don't believe that anyone has mentioned that cork borers must be sharpened fairly frequently if they are to bore a nice hole with a minimum of elbow
grease. I have one like this:
http://www.onlinesciencemall.com/Shop/Control/Product/fp/vpi...
United Nuclear also sells a nice looking hand-driven boring machine ($85). I haven't tried it, but if I were buying a cork borer, this would be on
the top of my list (scroll down):

Hell yeah. So's trying to find a supplier for tubing other than greasing up to the local high school
