According to the EN ISO 683-4 standard, free-cutting steels fall into the category of unalloyed or low-alloy quality steels with an increased sulphur content, although some variants may also contain lead. This special composition gives free-cutting steels their outstanding properties. The exceptional machinability of these steels is due to the presence of manganese sulphide and lead inclusions. These inclusions contribute to the excellent chip-breaking properties that make machining one of the main areas of application for free-cutting steels.

SwissCut® is a bright steel from the range of special free-cutting steels. A decisive feature in favor of this steel is its profitability. The high-performance free-cutting steels have been specially developed for high cutting speeds combined with long tool life.

The SwissCut® special free-cutting steels SC30, SC37, SC30Pb and SC37Pb have been specifically developed to maximize wear reduction and optimize cutting processes. This effect is particularly evident at cutting speeds above 100 m/min, while the SwissCut® special free-cutting steels SC37Pbplus and SC620Pbplus have an optimum chemical analysis to reduce the tendency to stick to the tool surfaces.

• Higher cutting speeds: The specific material modifications in SwissCut® enable higher cutting speeds, resulting in faster machining times.
• Longer tool life: An ingenious design of oxide inclusions suppresses tool wear, resulting in longer tool life.
• Very good chip formation: The precise design of the materials in SwissCut® enables optimal chip formation, resulting in smooth machining processes.
• High uniformity across batches: SwissCut® is characterized by remarkable consistency and uniformity across different batches.
• Marked increase in productivity: Thanks to the improved properties of SwissCut®, manufacturing companies can see an impressive increase in their productivity.
• High surface quality: The use of SwissCut® ensures outstanding surface quality of machined parts.
