We are currently reclassifying our product data in stages: in accordance with the international standard ISO 13399.

What is ISO 13399? And what does this mean for HORN customers?
ISO 13399 is the international standard specifically for cutting tools and ensures that tool data can be seamlessly imported into CAM, CNC and tool management systems. The reclassification results in new drawings and attributes. Item numbers, the ordering process, product range and quality remain unchanged.

You can find the revised product data in the updated catalogues, leaflets and in our eShop. The transition is taking place in stages: flyers detailing the innovations for 2026, which we are presenting at the AMB in Stuttgart, will feature ISO values exclusively. We are gradually updating our catalogues. You can download a list providing an overview of all parameters here.
