For bench jewellers and silversmiths forming oval bangles to repeatable sizes. This stepped cast iron mandrel provides four distinct oval profiles, removing the guesswork of a tapered tool and ensuring consistent geometry during hammer forming. It's the ideal forming tool for batch production work.

Key features

  • Four graduated steps provide distinct, repeatable sizes for bangle forming.
  • True oval cross-section maintains correct bangle geometry on every step.
  • Heavy-duty cast iron construction withstands repeated hammer forming.
  • Square tang ensures a secure, non-slip grip when held in a bench vice.
  • Smooth, machined working surface helps prevent marring of softer metals.

Who it's for

A core forming tool for UK silversmiths, bench jewellers, and jewellery makers working with silver, copper, and other non-ferrous metals. It is also suitable for apprentices and students learning fundamental shaping techniques.

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.
