Cutting tools made of High-Speed Steel achieve high hot hardness, wear resistance and fracture resistance at a hardness of over 60 to 67 HRC through hardening and tempering. The main alloying elements are Carbon, Tungsten, Molybdenum, Vanadium and Cobalt. High contents of carbide-forming elements lead to the formation of wear-resistant carbides in the microstructure.
High‑Speed Steels are engineered for the most demanding cutting applications—including drilling, milling, threading, broaching, gear cutting and reaming—where extreme wear resistance, hot hardness and toughness are essential.
Combining advanced alloy design with state‑of‑the‑art remelting and powder metallurgical technology (PM), these steels deliver high edge retention, thermal stability above 600 °C and outstanding fracture resistance.
Premium PM grades known as BÖHLER’s MICROCLEAN series offer ultra‑clean microstructures and exceptional carbide uniformity, ensuring longer tool life, fewer tool changes and highly reproducible machining performance. These qualities make BÖHLER high‑speed steels the preferred choice for industrial cutting tools, automotive tooling, consumer goods tooling, and precision cold‑forming applications.
The extensive portfolio enables tailored solutions for each cutting task, while value‑adding services—heat treatment, PVD coatings and additive manufacturing—further optimize tool performance.
Developed and produced in the specialized BÖHLER plant located in Kapfenberg, Austria, these HSS materials provide the reliability, durability and productivity required for modern high‑precision manufacturing.
