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.
