Ball Vise | 360° Swivel Jewelry Engraving and Stone Setting Tool
About This Ball Vise
The ball vise is a manual workholding tool designed for jewelry engraving, gemstone setting, ring holding, and precision bench work. Available in 3-inch and 5-inch sizes to suit different workpiece requirements and bench setups.
Both versions support 360° swivel positioning with an adjustable internal brake, allowing you to change the working angle without re-clamping. The self-centring jaw system secures rings, pendants, and compatible fixtures for controlled engraving and stone-setting work. The chrome-plated steel body provides stable bench mass while remaining practical to reposition.
Size Selection Guide
- 3-Inch — 78 mm ball, 47 mm max jaw opening, 2.6 kg. Best for compact jewelry work, close microscope positioning, and space-conscious benches.
- 5-Inch — 130 mm ball, 98 mm max jaw opening, 10.2 kg. Best for larger workpieces, wider clamping range, and improved bench stability.
Workpiece Fit and Setup Guide
- Choose the right size — Select 3-inch for compact jewelry work or 5-inch for larger workpieces and wider jaw range.
- Select the holder or fixture — Choose a suitable included ring holder, fixture, or jaw plate; protect delicate surfaces from direct marking.
- Mount the ring correctly — For ring work, place the ring around the black ring holder first, then clamp the holder horizontally in the vise.
- Centre and tighten — Align the workpiece between the jaws and tighten only enough to prevent movement.
- Set swivel resistance — Use freer movement for repositioning; increase resistance before applying directional tool pressure.
- Verify before working — Test the hold gently and confirm the vise sits on a stable, level bench surface.

Pro Tips
- Choose the 3-inch for compact jewelry work and microscope positioning; choose the 5-inch when you need a wider jaw opening or heavier bench stability.
- For ring work, mount the ring on the black holder first, then clamp the holder in the vise — do not clamp delicate rings directly without protection.
- Use moderate swivel resistance for small angle corrections, then increase resistance before applying directional tool pressure.
- Match the fixture to the workpiece shape and use protective material on delicate or polished surfaces to reduce marking.
- Remove metal dust and debris from jaw and moving areas after each session; follow the supplied service manual for cleaning and lubrication guidance.
FAQ
What is the difference between the 3-inch and 5-inch versions?
The 3-inch version has a 78 mm ball, 47 mm max jaw opening, and 2.6 kg body — suited for compact jewelry work. The 5-inch version has a 130 mm ball, 98 mm max jaw opening, and 10.2 kg body for larger workpieces and greater stability.
Can the ball rotate through 360 degrees?
Yes. Both versions support 360° swivel positioning with an adjustable internal brake from free movement to a locked position.
Does it require electricity?
No. The vise is fully manual. Engraving tools, setting tools, consumables, and protective equipment are selected separately.
Will it hold irregular shapes?
The self-centring jaws work best with symmetrical pieces. Irregular shapes require a suitable fixture and a stability check before work begins.
Is the 3-inch version suitable for microscope work?
Yes. The compact 78 mm ball and low-profile format suit close bench and microscope positioning, subject to the clearance of your own setup.
How should it be maintained?
Keep jaws and moving areas free of debris. Follow the supplied service manual for cleaning and lubrication guidance.
