Frequently Asked Questions

Q: What materials can this adjustable glass circle cutter score?

A: This tool is designed primarily for flat glass but can also be used to score ceramic, porcelain tiles, and other similar hard, flat surfaces. Always test on a scrap piece before cutting your final workpiece.

Q: What is the minimum and maximum circle diameter this cutter can make?

A: The adjustable arm allows you to score circles with a diameter ranging from 12 cm (approximately 4.7 inches) up to 20 cm (approximately 7.9 inches), covering a wide variety of common project sizes.

Q: How does the suction cup help with cutting accuracy?

A: The wear-resistant rubber suction cup acts as a central pivot point, anchoring the tool firmly to the glass surface. This prevents the center point from slipping during rotation, ensuring the cutter wheel traces a true, even circle every time.

Q: Do I need cutting oil to use this glass circle cutter?

A: Cutting oil is strongly recommended as it lubricates the carbide cutter wheel, reduces friction, extends the wheel's lifespan, and produces a cleaner, smoother score line. The bundle options (Types B–E) include cutting oil in the package.

Q: Is this tool suitable for beginners?

A: Yes! The round knob handle, anti-slip suction cup base, and clearly marked measurement scale make this glass circle cutter user-friendly for beginners while still delivering the precision that experienced craftspeople expect.
