Whilst the Glastar Circle Cutter works very well, it will only cut circles down to about 75 mm (3"). Cutting smaller circles requires a lens cutter.
This cutter cuts precise circles from 0.375 mm to 12.70 cm (3/8" to 5") diameter. It comes with a 3-wheel cutting head for long life. It is excellent for cutting lots of sun-catchers, holiday ornaments and medallions. Replacement cutting wheels are available.
