Jeu de 4 triboulets ronds miniatures pour chatons – Fabriqués en Allemagne

This set of four German-made mini high-carbon steel bezel mandrels is engineered for jewelers and metalsmiths who demand precision in bezel and jump ring work. Hardened to 58 HRC, each mandrel in this set is intentionally short, which means less taper across the covered size range — a significant advantage when forming tight, accurate bezel settings. The four mandrels together span 1.5 mm to 16.0 mm, giving you continuous coverage across a wide range of sizes. Top-quality German precision manufacturing throughout.

Product Tip: Carbon steel will rust if exposed to humidity. Moisture from fingerprints can cause rust, so keep steel tools clean after each use. A light coating of oil is all you need to protect the steel. Store tools covered with an oily rag when not in use. If rust appears, remove it with fine sandpaper. Carbon steel is far stronger than stainless steel and is the preferred material for professional jewelers' tools, including pliers, mandrels, and rolling mills.
