BÖHLER S607 – “The wear-resistant one” This grade has very high wear resistance while maintaining high toughness and perfectly acceptable machinability.

BÖHLER S630 – “The economical one” Tungsten-molybdenum high-speed steel with aluminum alloy for great toughness and good machinability. Universally usable for taps and twist drills, reamers, metal saws, mills of all types, and woodworking tools.

BÖHLER S690 MICROCLEAN – “The simple one” The tough high-speed steel for challenging machining and cold forming.

BÖHLER S705 – “The industrial one” The conventional high-speed steel for industrial applications in machining. With a well-balanced alloy position and cobalt content, this type always manages to get the job done. Cobalt-alloyed molybdenum high-speed steel with high hardness, excellent cutting properties, outstanding compressive strength, high hot hardness, and good toughness.

BÖHLER S790 MICROCLEAN – “The 1st MICROCLEAN” High-speed steel manufactured in a powder metallurgy process, with good hot hardness, compressive strength, and wear resistance. PM technology gives it good toughness and excellent workability, including the best machinability.

Uddeholm Vanadis 23 SuperClean is a high alloyed powder metallurgical high speed steel with a good abrasive wear resistance in combination with a high compressive strength. It is suitable for demanding cold work applications like blanking of harder materials such as carbon steel or cold rolled strip steel and for cutting tools. Benefits Uddeholm Vanadis 23 SuperClean is a powder metallurgical tool steel offering an excellent combination of wear resistance and toughness. The machinability and grindability are superior to conventional high speed steel and so is the dimensional stability after heat treatment.
