    General Product Description

    Pre-hardened, precise, predictable steel, now in round bars.

    Toolox® round bars are pre-hardened, ready-to-use quenched and tempered tool steels that come in a wide range of diameters from small to large.

    Suitable for engineering applications in tool holders and in different types of shafts and rolls, the diameter dimensions also provide a better solution for round parts in tooling applications like molding and in dies for aluminium die casting.

    Dimension Range

    Toolox® 44 round bars is available in diameters 21.0 - 282.0 mm. Other dimensions can be available on request.
