Stainless Steel Ring Block Ball Vise

Clamp and manipulate rings securely for stable stone setting, bright-cutting, and detailed jewelry finishing. The Stainless Steel Mini Ring Setting Ball Vise is a compact 1.21 kg fixture designed specifically for ring engraving and gemstone mounting. Featuring an expanding mandrel screw assembly paired with 7 split ring collet bushings, it secures the inner shank firmly without marring polished metal surfaces.

Why Choose the Stainless Steel Mini Ring Setting Vise

• Non-Marring Split Ring Bushings: Includes 7 graduated white split collet bushings designed to expand against the inner ring shank, providing a firm hold that prevents surface scratches or metal deformation.

• Flexible Multi-Angle Positioning: Smooth hemispherical base rests in a contoured rubber base ring, allowing technicians to tilt and adjust the working angle freely under a microscope or at the bench.

• Solid Stainless Steel Construction (1.21 kg): Substantial steel core provides stable vibration damping in a compact footprint (8.5 × 7.7 × 7.7 cm), keeping workpieces steady during pavé bead raising and prong tightening.

• Non-Slip Heavy Rubber Base: Contoured rubber base ring grips bench surfaces firmly to prevent shifting during delicate tooling operations.

• Fast Hex Key Setup: Complete with an L-shaped hex wrench for quick clamping, collet changes, and ring adjustments.
