Ring Sizing & Forming Mandrel — Solid Steel, Round, US Sizes 1–16, 13 Inch, Grip Handle
The reference tool for ring work: check a band against the engraved US 1–16 scale with its half-size markings, true a shank that has gone oval, or form new work directly on the taper. Solid steel gives it the mass and rigidity to take real hammer blows without deflecting — the quality our guide to choosing a ring mandrel tells you to look for first.
The working surface is hardened, smooth and evenly tapered, so rings glide on and off without marring, while the knurled steel handle keeps your grip certain mid-strike. At 13 inches overall there is room to work the metal and read the scale at the same time.
- Machined from solid steel for essential weight and rigidity when hammering.
- Engraved with US ring sizes 1 to 16, with clear markings for half sizes.
- Knurled steel handle provides a secure, non-slip grip during forming operations.
- Smooth, hardened, and tapered working surface allows rings to glide on without marring.
