M30X1 HSS die, DIN 22 568 – ultra-fine threading on large industrial diameters

The M30X1 threading die is a specialized tool for cutting external threads with a diameter of 30 mm and an ultra-fine pitch of 1 mm. Made from high-speed steel (HSS) hardened to 64 HRC in accordance with DIN 22 568, it provides the highest dimensional precision in large-scale applications. The M30X1 metric die is designed for machining structural steels with a tensile strength of up to 800 MPa and nonferrous alloys.

Key advantages of the M30X1 HSS round die

  • Hardened to 64 HRC – exceptional wear resistance when cutting ultra-fine threads on large cross sections
  • Ultra-precise pitch of 1 mm at a diameter of 30 mm – an extremely high number of threads ensures maximum connection strength and leak tightness
  • Medium tolerance class 6g per DIN 22 568 – general-purpose clearance fit with a maximum clearance of 0.15 mm for precision applications
  • Solid round construction – the solid body eliminates thermal deformation and ensures thread profile symmetry
  • Material range up to 800 MPa – efficient thread cutting in structural steels, aluminum, brass, and cast iron

The tool is used in high-pressure hydraulics, heavy machinery manufacturing, and the production of components with the highest strength requirements. The 6g tolerance ensures trouble-free assembly with 6H nuts. Professional workshops use the M30X1 die in applications requiring the absolute maximum number of threads within limited installation space and the highest resistance to loosening in environments with extreme vibration and dynamic loads.

Frequently asked questions

The M30X1 ultra-fine thread is used in high-pressure hydraulic systems operating above 400 bar, precision control valves, aircraft and spacecraft components, and connections requiring absolute leak tightness and maximum strength with minimal engagement length.

The outside diameter of the rod should be 29.82-29.92 mm for tolerance 6g according to DIN 22 568. Chamfer the rod end at 45° over a length of 7 mm and remove all burrs and surface irregularities before starting to cut the thread.

Due to the large diameter and ultra-fine pitch, machine threading with an axially compensating holder at 6-10 rpm is mandatory for steel. Reversing half a turn after every two full turns, applying ample lubrication with a pressurized cooling and lubricating emulsion, and eliminating all vibration are essential.
