Die M39x1 HSS DIN 22 568 – ultra-fine threading of very large cross sections

The M39x1 threading die is a specialized round die for cutting external threads with a diameter of 39 mm and an ultra-fine pitch of 1 mm. Manufactured from high-speed steel (HSS) hardened to 64 HRC in accordance with DIN 22 568, it provides exceptional dimensional precision in the most demanding applications. The M39x1 metric die is designed for machining structural steels with a maximum tensile strength of 800 MPa and special materials.

Key features of the M39x1 HSS round die

  • Hardened to 64 HRC – ensures long-lasting sharpness when cutting ultra-fine threads at very large diameters
  • Ultra-precise pitch of 1 mm at a diameter of 39 mm – an extremely high number of thread turns provides maximum strength and leak tightness
  • Accuracy class 6g according to DIN 22 568 – universal medium fit with controlled clearance for precision applications involving large components
  • One-piece round design – solid construction eliminates thermal deformation when machining large-diameter shafts
  • Material range up to 800 MPa – effective cutting in structural steels, aluminum, and cast iron

The die is used in ultra-high-pressure hydraulics, heavy machinery manufacturing, and wherever the absolute maximum thread count is required at large diameters. Professional workshops use the M39x1 die in the production of high-pressure hydraulic components above 500 bar, precision valves, and wherever maximum connection strength is a priority with limited engagement length in large structures.

Frequently asked questions

The M39x1 ultra-fine thread is used in ultra-high-pressure hydraulic systems above 500 bar, large precision control valves, industrial equipment, and connections requiring maximum leak tightness and strength at large diameters with minimal installation space.

The rod outside diameter should be 38.82-38.92 mm for tolerance class 6g according to DIN 22 568. Chamfer the end of the rod at 45° over a length of 9-10 mm before starting to cut the thread.

Chamfer the end of the rod at an angle of 45°, secure the workpiece in a vise or chuck that eliminates vibration, and guide the die perpendicular to the axis. Reversing half a turn after each revolution and applying generous lubrication with specialized threading oil are mandatory.
