olid steel mandrels for shaping and forming rings. The steel is strong enough to handle blows from a hammer when shaping or sizing. This mandrel features laser etched markings for ring sizes 1 to 16 (US) in 1/4 sizes. American made.
As with all PEPE Tools products, these mandrels are made with uncompromising quality for the price.
The mandrel is made of steel hardened to 44 hRc. That is hard enough not to be dented by missed hammer blows. The mandrel is also nickel and chrome plated them polished to a beautiful finish. The sizes measured to exacting ISO standards making it arguably the most accurate ring mandrel in the world.
This mandrel has a groove that is useful for rings that have stones set low in the ring with the culet exposed underneath.
