Mandrel V Groove 10mm to 25 x 350mm

Made in Italy with High Grade Steel. This V-Groove Ring Mandrel is designed for forming, sizing, and repairing stone-set rings without damaging delicate settings. The precision V-shaped groove provides clearance for the underside of prong and claw settings, allowing rings to be worked on safely while protecting stones and mountings from impact. Manufactured from hardened, polished steel, the mandrel offers a durable and smooth working surface for hammering, shaping, and resizing. The V-groove helps maintain the ring's shape and structural integrity, preventing distortion or warping that can occur when working on a standard flat mandrel. An essential tool for jewellers working with set stones and intricate ring designs. Mandrel sizes - 10 mm to 25 mm Total length - 350 mm
