🛠️ Adjustable Glass & Tile Circle Cutter – Precision Suction Cup Tool
⭕ Cut Clean, Accurate Circles with Confidence
Set the size, lock the suction cup and make one smooth score—ideal for glass projects, mirror work and suitable ceramic tile.
😤 Tired of Slipping Tools, Uneven Circles and Wasted Glass?
Freehand scoring can drift, repeated passes can chip the edge, and a weak base can ruin an expensive sheet. This adjustable cutter keeps the center fixed and the cutting path consistent.
🛠️ Built for DIY Renovators, Makers and Trade Professionals
Create controlled circular openings for craft pieces, mirrors, vents, lighting projects and home upgrades without relying on paper templates or shaky freehand lines.
The clear scale and large adjustment knob make setup approachable for beginners, while the stable base and oil-feed head support repeatable professional-style results.
- 🎯 Accurate Adjustable Sizing: Choose from two adjustable cutting ranges: 12–20cm (4.7–7.9in) or 12–40cm (4.7–15.7in), depending on the selected option.
- 🧲 Centered, Stable Cutting: The vacuum suction base helps prevent sliding and keeps the cutting path aligned.
- 💧 Smoother Oil-Fed Scoring: The integrated reservoir supplies lubricant to the wheel for a more continuous score.
- 🔒 Quick, Secure Adjustment: The large textured knob makes size changes and locking easier, even with work gloves.
🧡 Why It Works Better on Real Projects
Use the visible scale to set your target size without tracing separate circular templates.
A clean, locked suction cup keeps the pivot point stable as the arm rotates.
The oil-feed head helps reduce drag and supports a smoother single-pass score.
The broad base, lever lock and textured knob give you a steadier setup before scoring.
🧲 Strong Suction Helps Stop Costly Cutting Errors
Clean the surface, press the base flat and lock the lever. The vacuum cup holds the center point in place so the arm can rotate smoothly around one consistent path.
For best grip, use on a clean, smooth, non-porous surface and confirm the base is secure before applying cutting pressure.
💧 Self-Oiling Head for a Cleaner, More Consistent Score
The built-in oil reservoir feeds lubricant toward the cutting wheel as you work. This helps the wheel glide with less drag and reduces the need to stop repeatedly for manual lubrication.
⚠️ Use on Compatible Materials—Never Tempered Glass
Designed for non-tempered flat glass, mirror and suitable ceramic or glazed tile. Suitable for materials approximately 3–15mm (0.12–0.59in) thick, depending on the material and cutting technique.
Do not use on tempered, laminated or safety glass. Tempered glass can shatter when scored. Always confirm the material type and test on scrap material first.
🛠️ Four Steps to a Better Circle Cut
Lay the material on a flat, padded surface. Clean away dust, oil and moisture.
Adjust the scale to the required diameter, tighten the knob and lock the suction cup.
Rotate the arm with steady, even pressure. Complete one continuous pass—do not retrace.
Lightly tap along the score line, then work from the center outward to release the circle.
🏠 Made for Projects That Need a True Circular Opening
A practical tool for home improvements, repairs and creative glass work. Always confirm that the material is compatible before cutting.
⚖️ Adjustable Circle Cutter vs. Freehand Scoring
| Comparison | This Circle Cutter | Freehand / Template Method |
|---|---|---|
| Sizing | Calibrated Adjustable Scale | Separate Measuring & Tracing |
| Center Stability | Locking Suction Cup | Depends on Hand Control |
| Lubrication | Integrated Oil Feed | Manual Reapplication |
| Scoring Path | Consistent Circular Rotation | Higher Risk of Wandering |
⭐ Customer Review Templates
“I used it for a six-inch opening in a mirror project. The scale was easy to set, and scoring once gave me a much cleaner line than tracing by hand.”
“The suction cup held well after I cleaned the glass. I practiced on scrap first, then made the final cut without the center shifting.”
“The large adjustment knob is easier to tighten than the small screws on my old cutter. The ruler also saved time when making two matching circles.”
“The oil-feed head kept the wheel moving smoothly. It still takes patience to release the center, but the scored circle came out even and accurate.”

❓ Frequently Asked Questions
🪟 Can I use it on tempered glass?
No. Tempered glass can shatter when scored. Use only on compatible non-tempered materials and verify the glass type before starting.
📏 What circle sizes can it cut?
Two adjustable range options are available: 12–20cm (4.7–7.9in) and 12–40cm (4.7–15.7in). Select the range that matches your project and test the setting on scrap material first.
💧 Do I need to add cutting oil?
The head includes an oil reservoir. Add a suitable glass-cutting lubricant as needed and avoid overfilling. Follow the lubricant manufacturer's directions.
⭕ Why should I score the circle only once?
Retracing can create multiple fracture lines and increase chipping. Use steady pressure to make one continuous score, then release the circle gradually.
