Durston’s Bracelet Mandrels, created from tool grade steel which is then hardened to 64 RC and highly polished to reduce your finishing work. This is the small round mandrel enabling the shaping and forming of bangles and bracelets from 25mm diameter to 50mm diameter. The mandrel is 380mm long. Like all Durston tools, the bracelet mandrel is designed to last a lifetime in any professional jewellery workshop.
