Cork Drills
Cork Drills (Product Code: SCI-661/031) are hand-operated steel cork borers used to cut clean holes in corks and rubber stoppers so that glass tubes, thermometers and delivery tubes can be fitted into laboratory apparatus. The set covers 3 sizes from 5 mm to 7.5 mm in polished, chemical-resistant steel, a practical addition to lab equipment accessories in India. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Are Cork Borers Used For?
Building apparatus from stock parts nearly always means making a hole. With a cork borer, a solid stopper becomes the top of a gas generator carrying a delivery tube, a flask closure that holds a thermometer for distillation, or the head of a simple wash bottle. Choose a borer slightly smaller than the outside of the glass tube, so the finished hole grips the tube firmly. Schools and colleges buying lab equipment in India usually keep at least one set in the preparation room for this reason.
Mark the centre of the stopper, wet the cutting edge with water or glycerine when boring rubber, and press with a steady turning motion rather than brute force. Bore from the narrow end towards the wide end, keeping the borer upright for a straight hole. Clear the cut plug from the borer before the next hole, wipe the steel dry and store the borers so their cutting edges do not knock together.
What to Specify When Ordering
- The number of sets required (each covers 3 sizes, 5 mm to 7.5 mm).
- The outside diameters of the glass tubes or thermometers you will fit, so suitable sizes can be confirmed.
- Whether stoppers, corks or a borer sharpener should be quoted too.
OEM Manufacturer
Cork Drills are produced by Jain Scientific Equipments Private Limited, trading as ScienceLab, which is the OEM and makes them at its own licensed factory at Saha, Ambala, Haryana, India. Because the borers come from the manufacturer rather than a stockist, laboratories get one point of contact for quotations, extra sets and later top-ups — just ask us. Schools, colleges, dealers and importers are served factory-direct; details are on the ScienceLab company profile.
Related Laboratory Equipment
Boring a stopper is one step; these items complete the job:
- Cork Borer Sharpener — restores the cutting edge after repeated use.
- Rubber Stoppers without Holes Of Different Diameters — solid stoppers ready for boring.
- Cork Stoppers — natural corks to bore for tubes and thermometers.
- Glass Pipes of Different Diameters — tubing to pass through the new hole.
More bench tools are listed in the Laboratory Equipment category.
Frequently Asked Questions
Which sizes are included in Cork Drills?
Cork Drills come in 3 sizes spanning 5 mm to 7.5 mm. Choose the size slightly smaller than the outside diameter of the glass tube or thermometer you want to fit, so the finished hole grips it firmly. Ask us if you need each borer's size confirmed.
Can Cork Drills bore rubber stoppers as well as corks?
Yes, Cork Drills can bore both corks and rubber stoppers. For rubber, wet the steel cutting edge with water or glycerine and turn it steadily while pressing lightly; this gives a cleaner hole than forcing the borer straight through.
What are they made of?
Cork Drills are made of steel with a polished, silver finish and are described as chemical resistant. Wipe them clean and dry after boring to keep the polished surface and the cutting edges in good order between practical sessions.
Who manufactures Cork Drills?
Cork Drills are manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), acting as OEM, at its own licensed factory in Saha, Ambala, Haryana, India. The company sells them factory-direct to schools, colleges, dealers and importers, so quotations come from the maker itself.
How do I keep the borers sharp?
Keep Cork Drills sharp by storing them so the cutting edges do not knock together and by honing them when holes start to tear rather than cut cleanly. A cork borer sharpener, listed separately by ScienceLab, restores the edge.
What should a quotation request include?
To get a quotation for Cork Drills, send the number of sets, your delivery location and any stoppers, corks or glass tubing to be priced together through the contact page. Bulk and export enquiries for India and international markets are welcome.
