Description
The Cork Borer Set, also known as a laboratory stopper hole punch set, is designed for boring clean holes in corks and rubber stoppers. It is suitable for school laboratories, university teaching laboratories, chemistry laboratories, biology laboratories and general laboratory preparation areas where stoppers need to be prepared for inserting glass tubing. The nickel-plated brass borer set includes multiple cork borers with a rod for practical bench handling. The listed six-piece set includes inside bore sizes of 8.45 mm, 7.5 mm, 6.3 mm, 4.9 mm, 4.0 mm and 3.4 mm, allowing users to select the required hole size according to the stopper, tubing and apparatus setup.
These cork borers are commonly used when assembling laboratory apparatus that requires glass tubing to pass through a cork or rubber stopper. They support cleaner and more controlled hole preparation compared with forcing tubing through an unprepared stopper. The tools are also listed for taking samples during experiments and punching holes on agar plates. These tasks should be performed using suitable laboratory technique, appropriate supervision and the correct borer size for the material being used.
The overall length of the listed borer set is stated as 100 mm, supporting controlled handheld use during routine preparation work. Users should apply steady pressure and avoid twisting or forcing the tool beyond its suitable cutting capacity. The chrome-plated metal cork borer sharpener is designed to restore cork borers when the cutting edge becomes dull over time. Keeping the cutting edge sharp supports cleaner holes, easier operation and longer useful tool life.
LabChoice Australia supplies Cork Borer Sets and Cork Borer Sharpeners for school science laboratories, university teaching laboratories, chemistry laboratories, biology laboratories and general educational laboratory settings. These tools are suitable for preparing cork and rubber stoppers, inserting compatible glass tubing, supervised sampling activities and agar plate hole punching under appropriate laboratory supervision.
