Cork Borer With Plastic Handle, Set Of 6

  A cork borer, often used in a chemistry or biology laboratory, is a metal tool for cutting a hole in a cork or rubber stopper to insert glass tubing. Cork borers usually come in a set of nested sizes along with a solid pin for pushing the removed cork (or rubber) out of the borer. These units are nickel-plated brass with a handle and punch. The handles are numbered for identification.
