Toolox 33 round bars

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

Toolox 33 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.
