$59.4 $99 In stock

Introducing a unique oval mandrel crafted from a specialized drop forge process, this tool boasts a super fine mirror finish for flawless work. The mandrel is expertly hardened to a range of 48-52HRC, ensuring resilience and long-lasting performance.


The sleek black mandrel is treated with an advanced Diamond Like Composition (DLC) coating, achieving a stunning, wear-resistant black finish. With a nano-hardness of 2300HV and a low friction coefficient of 0.1, it promises unparalleled quality. Alternatively, choose the radiant gold TiN variant, coated with Titanium Nitrite for an extra hard, golden surface that translates its superior finish to your workpiece, ensuring it is smooth, flat, and perfect.

The mandrel measures a total of 330mm (13 inches) in length, including a 100mm (4 inches) handle measuring 20mm diameter for a comfortable grip. The working area extends 230mm (9 inches), featuring an oval taper that starts at 34mm x 12mm at the bottom and narrows down to 26mm x 8mm, allowing for a range of ring sizes and shapes.

Your mandrel arrives in a protective box, perfect for safe storage and transport. The felt-lined box has a custom-fit cutout that snugly secures the mandrel, providing protection against wear. Whether for professional jewelers or hobbyists, this mandrel offers the perfect blend of beauty and functionality, ensuring your creations are as flawless as your craft demands.

Grace P. ★★★★★

I was a bit skeptical about the mirror finish, but it's so smooth that my metal slides off without any snagging. The oval shape is perfect for the ring designs I've been working on.

Miles J. ★★★★★

The drop-forged construction gives it a solid, balanced heft that you can feel the moment you pick it up. Even after working with it for a while, the mirror finish still looks flawless and hasn't picked up any scratches. Hardness sits right where you'd want it for shaping without worrying about ding

Ava ★★★★★

The mirror finish on this mandrel is flawless, and it handled a delicate bezel shaping project without leaving a single scratch. The drop forge process clearly makes a difference in the durability.
