The Durston 1509 Steel Plain Round Mini Bezel Mandrel is a precision-ground forming tool designed for shaping small round bezels and other circular metalwork in non-ferrous metals including gold, silver, and brass. Tapering from a minimum diameter of 4mm (5/32") at the narrow end to a maximum diameter of 12.5mm (1/2") at the widest point, this miniature mandrel covers a practical range for fine bezel and ring work at a smaller scale. The total length including the tang measures 270mm (10‑3/4"), giving the jeweler secure grip and control during use.
Crafted from steel, this plain-surface mandrel provides a smooth working profile ideal for forming and sizing round components without interference from taper steps or markings. Its compact diameter range makes it especially well-suited for small stone settings, tube bezels, and fine forming tasks where a standard-sized mandrel would be too large.
