Sizing and truing rings is daily work at the bench, and this mandrel covers both. UK sizes 1 to 15 are engraved in half-size increments for reading a shank at a glance — worth pairing with our guide to measuring ring size when a customer only knows 'about a medium'. The continuous groove along the taper seats the ring and stops it slipping while you work.

Solid aluminium keeps the weight down compared with steel — something your forearm notices by the end of a resizing session — and the smooth cylindrical handle holds well in hand or vice. The squared-off tip stops the mandrel rolling off the bench. A sound first mandrel for a student, and a light second one for the established bench.

  • Clearly engraved UK ring sizes from 1 to 15 with half-size increments.
  • A continuous groove along the tapered body secures the ring during forming.
  • Solid aluminium construction is lightweight for comfortable, extended use.
  • Smooth, cylindrical handle provides a secure grip in the hand or vice.
  • Squared-off tip helps prevent the tool from rolling on the bench.

Who it's for

An essential sizing and forming tool for UK bench jewellers, silversmiths, and jewellery repair workshops. Also well-suited for students and apprentices learning ring making and alteration techniques.

Customer Reviews (4.6 / 5 · 5 reviews)

John ★★★★★

The grooves are deep enough that the ring doesn't slip even when I'm hammering a stubborn kink out, and the silver finish doesn't tarnish after a few weeks of sweaty workshop use. Sizing a shank against the half-marks takes seconds now.

Miles ★★★★★

The engraved half-size markings are crisp and easy to read even under a loupe, which saves time when truing a bent shank. It’s solid enough to handle repeated hammering without dents forming on the surface.

Penelope V. ★★★★★

The grooves are deep enough that my ring doesn't slip even when I'm hammering it back into round, which was my main worry with a cheaper mandrel. The engraved numbers are also surprisingly easy to read in dim bench light, so I don't squint every time I check a size.
