Adjustable Circular Glass Scoring Cutter

Score circular shapes in suitable glass with an adjustable compass-style cutter and suction-cup centre.

✅ Keep the circle centred - The suction cup holds the centre position while the cutting wheel follows the arm.

✅ Set the required circle size - An adjustable arm and scale provide the described radius-setting arrangement.

✅ Guide the movement by hand - A round knob gives you the described grip while rotating the cutter.

Score the circle before separating the glass

A circle cutter helps guide a consistent circular score rather than relying on a freehand line. Place it on clean suitable glass, set the size and check that the suction centre is holding before scoring.

The wheel scores the surface; separating the circle still requires the correct glass-working technique. Use suitable eye and hand protection, and check that the glass type and thickness are appropriate before starting.
