Cork Borer, Set of 12
This set of six cork borers allows you to make uniform holes in rubber stoppers and corks to meet a variety of laboratory needs. The standard holes in rubber stoppers are 3 mm or 5 mm depending on the stopper size. Often a larger hole is needed to attach glass tubing, thermometers, funnels, glassware, or other equipment.
This set of twelve nickel-plated brass cork borers ensures you can always make the right size hole when you need it. You can also make your own holes in economical corks instead of pre-drilled rubber stoppers or just keep a few solid rubber stoppers on hand instead of pre-drilled stoppers in every size.
Includes 12 borers allowing you to create holes ranging from 4.5mm to 13mm in diameter, and a push rod cleaning the borers.
