M90x2 HSS DIN 22 568 die – threading extremely large diameters in industrial applications

The M90x2 die is a round tool with multiple cutting edges, made of high-speed steel (HSS) with a hardness of 64 HRC, designed for cutting external metric threads with an extremely large diameter of 90 mm and a pitch of 2 mm. This tool is a specialized solution for shops servicing the largest industrial machines, steel structures, and power generation equipment. Compliance with DIN 22 568 and a 6g tolerance ensure proper fit with 6H nuts in the largest heavy industry applications. The 90 mm diameter is one of the largest standard die sizes, making this tool essential equipment for specialized industrial shops.

Main advantages of the M90x2 die for extremely large dimensions

  • Diameter of 90 mm for the largest structures – this size makes the tool suitable for turbine main shafts, large cylinder rods, and structural foundation components in power generation and heavy industry
  • Standard pitch of 2 mm – conventional pitch providing adequate mechanical strength of the connection while allowing efficient thread cutting despite the extremely large dimensions
  • HSS steel hardness of 64 HRC – provides exceptional abrasion resistance and maintains cutting performance when cutting the largest-diameter threads in structural steels with tensile strengths up to 800 MPa
  • 6g tolerance according to ISO – standard medium fit with normal clearance allows nuts to be fitted without binding despite the extremely large dimensions of the threaded connection
  • Solid round construction – one-piece construction without segments provides the maximum rigidity essential for threading the largest diameters under extreme cutting forces

The M90x2 die is a tool for highly specialized industrial shops serving the power generation industry, shipyards, mining, and steel structures with dimensions exceeding all typical standards. It is suitable for cutting threads on the main shafts of the largest machines, large hydraulic cylinder rods, and foundation rods in bridges and industrial structures. Due to the extremely large dimensions, threading requires a powered drive (lathe or specialized threading machine), highly rigid die stocks, generous lubrication, and highly qualified operators.

Frequently asked questions

The recommended stock diameter is 89.5 to 89.6 mm. At the extremely large diameter of 90 mm, even minimal deviations from the recommended diameter can drastically increase cutting forces and the risk of tool damage.

Manual threading at a diameter of 90 mm is virtually impossible due to the extreme torque required. A powered drive is mandatory – a lathe, a specialized threading machine, or at least an electric drive with a reduction gearbox.

Threads with a diameter of 90 mm are used in the largest power generation machines (steam turbines, generators), shipyards (ship drive shafts), the extraction industry (mining machinery), and bridges, dams, and industrial structures requiring the largest threaded connections.
