Ring Sizing & Shaping Mandrel — Grooved Aluminium, US Sizes 1–15, Silver

Sizing and truing rings is daily work at the bench, and this mandrel covers both. US sizes 1 to 15 (the numeric scale — UK sizes are letters, A to Z) 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 US 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
