In the world of machining, the ISO classification is the most important standard. For mixed production, choose ISO-UNI, for steel ISO-P, for stainless steel ISO-M, and for cast materials ISO-K. ISO-N denotes non-ferrous metals, and ISO-S designates high-temperature materials, also known as superalloys. ISO-H designates hardened steels. ISO-O provides tools for composite materials, graphite, and natural materials such as wood.
