Square-section rings lose their character the moment a corner rounds over. Formed on a round mandrel, square stock distorts; formed on this dedicated square mandrel, the 90-degree geometry survives hammering and truing. The taper runs from 15x15mm down to 6x6mm, covering a wide range of ring sizes in square profile. Choosing between profiles? Our guide to choosing a ring mandrel lays out the options.

It is machined from a single piece of solid steel, so it takes hammer work without complaint, and the 13-inch (approx. 330mm) length gives a generous working area for gold, silver and other non-ferrous stock. The plain cylindrical handle holds securely in a vice or in hand.

David W. ★★★★★

The square edges on this mandrel are precise and sharp, exactly what I needed to keep 10mm sterling silver wire from rolling over. It’s heavy enough that it doesn’t shift on my bench while I’m hammering.

John V. ★★★★★

Finally, a mandrel that keeps my square wire crisp—the taper from 15mm down to 6mm is perfect for sizing rings without wrecking the edges. Corners stay sharp through every hammer blow, no more rounding over.

Ruby ★★★★☆

I was worried the tapers would be too abrupt for my smaller ring sizes, but the 15mm to 6mm range handles them perfectly. The steel really does keep those sharp corners crisp, no rounding at all. Only wish it had a slightly smoother finish right out of the box.
