Key Features
- Wide Compatibility: Scores glass tubing from 1mm to 50mm OD — works on borosilicate and flint glass tubing for clean, precise breaks.
- Tungsten Carbide Cutting Wheel: Hardened tungsten carbide wheel ensures long-lasting sharpness and smooth, consistent scoring with each pass.
- Stainless Steel Construction: Durable, corrosion-resistant stainless steel body provides a secure, comfortable grip and extended tool life.
- Replaceable Cutting Wheel: When the wheel eventually wears down, simply swap it out — no need to replace the entire tool.
- Easy Breaking Technique: After scoring, alternate cold and hot water over the scored line and the glass tube will break cleanly along the path.
- Compact & Handy: Lightweight and easy to manoeuvre, making it ideal for both workshop and lab use.
How to Use
- Position the cutting wheel on the glass tube at your desired cut point.
- Rotate the cutter firmly around the tube's circumference to score a clean line.
- Alternate pouring cold and hot water over the scored groove — the thermal stress will cause a clean break along the score line.
⚠ Safety Notice: Always handle glass with care. Wear protective gloves and eyewear when scoring and breaking glass tubing to avoid injury.

Frequently Asked Questions
Q: What types of glass tubing can this glass tube cutter score?
A: This glass tube pipe cutter is designed to score both borosilicate and flint glass tubing. It handles outer diameters from 1mm up to 50mm and wall thicknesses below 30mm, making it suitable for a wide range of laboratory, craft, and DIY glass tubing projects.
Q: Does this tool cut all the way through the glass tube in one pass?
A: No — this cutter scores a clean groove around the circumference of the glass tube rather than cutting all the way through. Once scored, you alternate pouring cold and hot water over the groove, which causes the thermal stress to snap the tube cleanly along the scored line.
Q: Is the tungsten carbide cutting wheel replaceable?
A: Yes! The tungsten carbide cutting wheel is fully replaceable. When the wheel wears down over time, you can swap it out to restore full cutting performance without needing to purchase an entirely new tool.
Q: What safety precautions should I take when using this glass tube cutter?
A: Always wear protective gloves and safety eyewear when scoring and breaking glass tubing. Handle broken glass with care and dispose of glass fragments safely. Keep the cutter away from children and store it in a secure location when not in use.
