Achieve consistent bangle diameters with this cast iron stepped mandrel, ideal for forming round bracelets at the bench.

What it does

This robust, ten-inch steel mandrel provides four precisely machined, fixed diameters, eliminating the guesswork of tapered tools. Form repeatable bangle sizes from 2 to 2-3/4 inches with confidence. The square tang ensures a secure grip when mounted in a bench vise, allowing for controlled, forceful shaping of sheet metal and wire. Its solid construction offers durability for frequent use.

How to use it

  • Secure the tang firmly in a bench vise.
  • Hammer or form your metal around the desired step.
  • Wipe clean after use to prevent tarnish.

Who it's for

An indispensable tool for UK silversmiths, bench jewellers, and jewellery students. It streamlines the production of identical bangles and bracelets, replacing the need for multiple individual mandrels or imprecise forming methods for batches.

Common questions at the bench

UK or US sizing?
Our steel ring mandrels carry both UK alphabetical and US numerical scales unless the product specifically notes UK-only or US-only in the description. Hardwood and aluminium mandrels are unmarked — use a separate ring sizer to measure.
Can I hammer directly against the mandrel?
Steel mandrels yes — that is what they are designed for. Hardwood mandrels are for forming and finishing only; hammering against them dents the wood and marks the workpiece. Aluminium mandrels: light planishing only, no forging.
What is a stepped mandrel for?
Stepped (tiered) mandrels let you work batches of rings or bangles in fixed standard sizes — useful for production work where you are making matched pairs or a series. Tapered mandrels suit one-off resizing where you need every size in between.
How do I store it without rust?
Wipe with a light camellia or 3-in-1 oil after wet work or polishing, then store in a dry drawer or wall rack. A small silica gel pack in the drawer is cheap insurance against humidity in unheated workshops.
