Precision round steel – ground and ready for use
Perfect application for shafts, molding tools, and rotating components.
When maximum dimensional accuracy and perfect rotational symmetry are essential, our ground precision round steel is the first choice. With tight tolerances—e.g., h8—and high-quality surfaces, it is ideal for demanding applications such as shafts, guides, forming tools, and other rotating components.

FAQ
Here you will find answers to frequently asked questions. For detailed technical data or
price information, please visit our online shop directly.
What is the tolerance range for precision round steel?
Our precision round steel is supplied in a ground finish and in the narrow tolerance class h8.
What is the surface finish of the precision round steel?
The round steel is delivered bright ground or bright drawn/fine peeled/ground and has a scale-free surface.
For which applications is precision round steel particularly suitable?
It is ideal for molding tools, punching tools, machine parts, standard parts, and construction elements, as it has perfect rotational symmetry thanks to its precision machining.
What materials are available for round steel?
We stock a selection of heat-treated and non-heat-treated tool steels, cold work steels, and plastic mold steels. Other materials are available on request.
