Durston® Hardened Ring Mandrel Oval 8.5 x 11 – 18 x 22

The Durston® Oval Hardened Steel Ring Mandrel is a professional-grade workshop stake engineered for wrapping, rounding, and work-hardening anatomical ring bands, heavy bezel walls, and custom jewelry shanks.

Forged from induction-hardened tool steel and ground to a smooth, matte finish, this 1kg bench tool provides an unyielding metallic foundation. The precise oval taper matches the natural, slightly flattened profile of the human finger, allowing individual creators to forge comfortable, top-heavy statement rings and wide bands smoothly without risking flat spots, edge distortion, or structural marring on highly polished silver and gold stock.

Key Product Features

• Induction-Hardened Solid Tool Steel: Precision-machined from premium hardened steel built to withstand intensive workshop hammering without dimpling, chipping, or bending over a lifetime of active studio service.

• Ground Precision Oval Taper: Features a continuous, seamless 320mm working barrel that expands gradually from an 8.5 x 11mm tip up to an 18 x 22mm base, providing accurate curvature transitions.

• Ergoved Polyurethane Grip Handle: Outfitted with a durable, grooved black handle that dampens high-frequency impact vibrations. The non-slip texture keeps the mandrel stable in your hand or resting inside a standard bench cradle holder.

• High-Density Energy Rebound: Weighs a solid 1kg. The dense structural mass naturally absorbs intense striking shock waves, lowering hand fatigue and stopping annoying bench bounce.
