Slide the arm along the guide rail and lock it at your desired radius to cut everything from small porthole-style circles to larger decorative disc shapes in flat glass.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this glass cutter suitable for mirrors as well as window glass?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The tungsten carbide cutting wheel scores cleanly on standard flat glass, window glass, and mirror glass. It is designed for use on flat glass surfaces — it is not intended for tempered, laminated, or safety glass.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How does the suction cup anchor work?\u003c\/h4\u003e\n\u003cp\u003eA: Simply press the central suction cup firmly onto the clean, flat glass surface at your desired center point. The suction holds the pivot in place while you rotate the cutter arm around it, ensuring a stable, consistent score line throughout the cut.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Do I need any special equipment to complete the cut after scoring?\u003c\/h4\u003e\n\u003cp\u003eA: After scoring, you can use a glass running plier or gently tap along the score line from underneath to propagate the break cleanly. No power tools are required — this is a fully manual process.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What size circles can this circular glass cutter cut?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The adjustable compass arm allows you to set a wide range of circle diameters.
