Heavy-duty jump ring making combo for 110–120 V benches, pairing the Durston 1309 Complete Jump Ringer with a premium Foredom SR flex shaft kit. Once set up, coils wind and cut smoothly while the motor hums overhead and finished rings fall neatly into place.

- All major components in steel (aluminum stand), giving extra rigidity and stability under continuous use
- Works with a #30 style handpiece and flex shaft to mass-produce jump rings from soft non-ferrous jewelry wire
- Makes jump rings from wire up to approx. 13 ga (1.85 mm) with inside diameters from about 2 mm to 12 mm
- Improved design includes an integrated coil holder in the main base and a movable safety coil winder
- Longer 4-3/4" mandrels and coil holder allow more jump rings per coil for efficient production
- High stem rotates a full 360° to give better hand clearance and comfortable cutting positions
- Included Foredom SR 1/6 HP reversible flex shaft kit (110V) provides smooth, controllable power up to 18,000 RPM

- Foredom SR motor and FCT foot control in this combo are for 110–120 V mains only (115 V rated).
- Not for use with platinum, titanium, steel, or niobium wire.
Notes
- Use only soft, non-ferrous jewelry wire (such as gold, silver, copper) within the specified gauge range.
- Always secure coils in the coil holder and use the safety coil winder correctly before cutting.
- Let the saw blade cut at an appropriate speed and feed rate to reduce burrs and extend blade life.
- Inspect and maintain the flex shaft, handpiece, and jump ringer regularly for smooth, safe operation.
