Frequently Asked Questions

Q: What materials can this circular glass cutter cut?

A: This heavy-duty circular glass cutter is designed primarily for flat glass panels, mirrors, and ceramic tiles. It works best on smooth, flat surfaces and is suitable for windows, artwork glass, bathroom tiles, and similar projects.

Q: How do I set the cutting radius on this adjustable circular cutter?

A: Simply slide the cutter arm along the scale bar to your desired radius and lock it in place. The clearly marked scale makes it easy to set precise measurements from 100 mm up to the maximum radius of your chosen tool size (200 mm to 2000 mm).

Q: Does the suction cup work on all glass surfaces?

A: The suction cup anchor is designed for smooth, flat, and clean glass surfaces. Ensure the glass is free of dust, moisture, or debris before pressing down the suction cup for optimal grip and a stable, accurate cut.

Q: Do I need to add oil to the cutter before use?

A: Yes — for best results, fill the built-in oil reservoir with cutting oil or kerosene before use. Lubrication reduces friction on the cutter wheel, resulting in a cleaner score line and extending the life of the cutting wheel.
