Ring Stretching & Enlarging Tool, Sizes 2–14 — Manual Metal Expander with Black Handle
A robust manual ring stretcher designed for controlled resizing of plain metal bands on the jeweller's bench.
What it does
This tool precisely expands rings using a screw-driven mechanism, offering a gentler alternative to hammering. Its hardened steel segmented mandrel, precisely machined for accuracy, gradually increases the ring's diameter without deforming its profile. The ergonomic T-handle provides leverage for controlled, incremental adjustments, ensuring a secure fit for customer repairs and custom work. The polished metal construction signifies its durability for daily workshop use.
How to use it
- Place the ring onto the segmented mandrel.
- Turn the T-handle to gradually expand the ring.
- Wipe clean after use to maintain the finish.
Who it's for
Essential for UK bench jewellers, silversmiths, and repair technicians working with plain bands. This tool is ideal for those moving beyond basic resizing or seeking a more controlled method than a hammer. It's a practical addition for apprentices and hobbyists needing a reliable, bench-ready solution.
