Always test on a scrap piece before cutting your final workpiece.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the minimum and maximum circle diameter this cutter can make?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How does the suction cup help with cutting accuracy?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Do I need cutting oil to use this glass circle cutter?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this tool suitable for beginners?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What materials can this adjustable glass circle cutter score?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This tool is designed primarily for flat glass but can also be used to score ceramic, porcelain tiles, and other similar hard, flat surfaces.
