For jewellers hammer-forming five-sided bangles, maintaining a crisp pentagonal profile is essential. This solid wood mandrel provides the five flat faces required for shaping, ensuring the geometry is not lost, which can happen when using a standard round or oval mandrel.
Key features
Features a true pentagonal cross-section for accurately forming five-sided profiles.
Crafted from solid wood to prevent marring of non-ferrous metals during forming.
Provides five stable, flat faces to support the bangle's geometry during hammering.
Measures 14 inches in length, offering ample space for shaping and adjustments.
Supplied as smooth, unfinished wood, ready for immediate use at the bench.
Who it's for
A specialist tool for UK bench jewellers and silversmiths creating contemporary bangles with a pentagonal cross-section. It is also suitable for students and apprentices learning geometric forming techniques in silver, copper, and other non-ferrous metals.

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.
