Delux Ring Stretcher

Enlarge, resize, and reshape precious metal wedding bands, plain ring shanks, and custom mountings with smooth mechanical torque. Engineered from solid tool-grade steel, the Deluxe Handheld Rotary Ring Stretcher provides high-efficiency ring expanding without requiring bulky bench-mounted presses or hammer blows. Equipped with a segmented expansion mandrel featuring three different clearly engraved measurement scales.

Why Choose the Deluxe Handheld Ring Stretcher

• Dual-Handle Mechanical Rotary Drive: Combines a textured side stabilizer grip with an oversized ergonomic T-handle turning knob, allowing you to generate smooth, controlled expanding torque with minimal physical effort.

• 3 Clear Engraved Measurement Scales: High-contrast graduations clearly marked along the expansion spline provide real-time visual tracking of ring movement across three distinct reference scales during resizing.

• Upgraded Built-In Spring Return: Features an internal tension spring assembly that automatically retracts the segmented mandrel splines when reversing the T-handle, ensuring smooth ring removal without sticking.

• Double-Lock Anti-Loosen Tip Assembly: The reinforced expansion stick head is secured with a heavy-duty retaining collar to keep the segments aligned and prevent them from loosening under expanding pressure.

• Solid Steel Construction (1.143 kg): Solid, mirror-polished steel mandrel and chrome-plated body resist surface galling, deformation, and wear across thousands of sizing operations.

• Compact & Portable Bench Footprint: At 330 x 95 x 45 mm, it delivers the resizing power of floor- or bench-bolted machines in a compact, portable form factor that stores easily in bench drawers or travel kits.
