Category: Jewellery Making Tools

Master ring resizing with this dual-action jewellery machine, precisely stretching and reducing bands at the bench.

What it does

This robust bench-mounted tool efficiently alters ring sizes. Its hardened steel, six-spline mandrel smoothly expands plain bands up to size 16. For reduction, a rotating plate with eight polished cavities offers controlled shrinking. The substantial cast-metal body and long lever ensure consistent, measured force application for precise adjustments.

How to use it

  • Securely mount the machine to your workbench.
  • Select the appropriate mandrel or reduction cavity.
  • Apply steady lever pressure for size adjustment.

Who it's for

Essential for UK bench jewellers and repair workshops, this tool streamlines resizing plain gold, silver, and other malleable metal bands. It replaces separate stretching and reducing tools, offering a consolidated and efficient solution for professional workflows.

Customer Reviews (4.4 / 5 · 5 reviews)

Elizabeth F. ★★★★★

The wooden handle gives you way more control than I expected, and swapping between stretching and reducing took me maybe two minutes to figure out. I've used it on several bands from 4 to 14 and the hardened steel dies haven't shown a single mark yet.

William ★★★★★

Took a size 9 band down to a 7.5 without any wobble or slippage — the hardened steel rollers held it steady the whole time. The dual-action really does save you from owning two separate machines.

Owen O. ★★★★★

Finally, a tool that handles both stretching and reducing on the same machine — the wood handle gives it a nice, solid grip during use. My size 6 band went up to a 7 without any trouble, and the bench mount kept everything steady.
