Glass cutter Dedra JOBO with 6 steel wheels model S320.0

The Dedra JOBO glass cutter S320.0 is a hand-held tool equipped with six hardened steel cutting wheels designed for scoring and cutting flat glass sheets. Its multi-wheel head provides options to rotate worn wheels into position, extending usable life and helping maintain consistent scoring depth for straight and curved cuts. The compact, lightweight body is intended for manual operation on window glass, mirrors, picture glass and craft glass, offering a practical solution for both DIY and professional tasks where controlled scoring and snap-off are required.

Advantages

The six steel wheels reduce downtime by allowing the user to switch to a fresh wheel as others wear, improving tool longevity without replacing the entire cutter. Hardened wheels deliver predictable scoring with reduced risk of skipped marks, which supports cleaner snaps and fewer edge chips. The hand-held form factor gives tactile feedback during scoring for improved control on detailed or curved cuts. The simple mechanical design requires no power source and is easy to clean and maintain.

Suitable for

• Scoring and cutting window glass and mirror sheets
• Cutting picture frame glass and small craft glass pieces
• Making straight and gentle curved cuts in thin to medium-thickness glass
• Workshop and on-site glazing or repair jobs

Key specifications

• Tool type: hand-held glass cutter with rotating wheel head
• Cutting wheels: six hardened steel wheels for repeated rotation
• Operation: manual scoring requiring subsequent snapping of the glass
• Suitable glass types: flat window glass, mirror glass, picture and craft glass
• Typical use: straight and gentle curved scoring on thin to medium-thickness glass

How to use

Place the glass on a stable, flat surface and support it near the intended score line. Select a fresh wheel if required and hold the cutter at a low, consistent angle with firm but even pressure. Score the glass in a single continuous stroke from one edge to the other without stopping. After scoring, position supports close to the score line and apply gentle bending or use pliers to snap the glass along the score. Inspect the cut edge and finish with a stone or file if required to remove burrs.

Usage recommendations

Use safety gloves and eye protection when scoring and breaking glass. Ensure the glass is clean and free of debris to achieve consistent scores. For thicker or tempered glass, use appropriate tools and techniques, as this hand-held cutter is intended for standard flat glass and mirror sheets rather than tempered or laminated types.
