Jump Ring & Loop Forming — Mini Triangle Mandrel Set, 6 Sizes 4–14 mm, with Handle

Triangular jump rings and angular wire components are awkward to form freehand; wound on a mandrel they come out identical every time. This set gives you six triangular formers from 4 mm up to 14 mm, so a whole run of findings — jump rings, links, decorative elements — comes off the tool with the same crisp profile. Our wire gauge guide helps when planning stock for a batch.

Each steel mandrel locks into the handle's set-screw chuck, with a flat ground on the shank so it cannot rotate under winding tension. A slot at the tip anchors the wire end before you start the wrap. Six sizes, one handle, and a small footprint in the tool drawer.

• Features six interchangeable steel mandrels covering a 4mm to 14mm size range.
• The supplied handle uses a set-screw chuck to securely grip each mandrel bit.
• Each mandrel blade has a triangular profile for forming sharp, consistent loops.
• A slot at the tip of each mandrel secures the wire end to make wrapping easier.
• Mandrel shanks are flattened on one side to prevent rotation within the handle.

Who it's for

A practical tool for UK bench jewellers, jewellery students, and wire artists creating their own findings or distinctive wirework designs. It is ideal for producing small batches of triangular jump rings and decorative components with a consistent profile.
