For jewellers forming contemporary square-section rings, maintaining crisp corner geometry is critical. This UK-stocked, solid steel square mandrel provides a dedicated forming surface, preventing the distortion that occurs when using a standard round mandrel for square-profile wire and stock.

Key features

  • Tapers from 15x15mm down to 6x6mm to form a wide range of ring sizes.
  • Machined from a single piece of solid steel suitable for hammering.
  • Maintains true 90-degree corners on square-profile wire and stock.
  • Measures 13 inches (approx. 330mm) in total length for a generous working area.
  • Features a plain cylindrical handle for secure holding in a vice or by hand.

Who it's for

An essential forming tool for UK bench jewellers, silversmiths, and jewellery students working with square-profile stock. Ideal for creating contemporary rings in gold, silver, and other non-ferrous metals whilst preserving the integrity of the design.

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.
