Die M25x1 left-hand HSS DIN 22 568 – left-hand extra-fine threading on large cross sections
The M25x1 left-hand metric die is a specialized round die for cutting external left-hand threads with a diameter of 25 mm and an extra-fine pitch of 1 mm. Made from high-speed steel (HSS) hardened to 64 HRC, compliant with DIN 22 568, it ensures the highest dimensional precision in the most demanding applications. The M25x1 left-hand threading die is intended for use in structural steels with a maximum tensile strength of 800 MPa and nonferrous alloys.
Main advantages of the M25x1 left-hand HSS round die
- Left-hand ultra-fine thread – triple protection through a left-hand thread direction, an extremely high thread count, and maximum frictional contact area
- Hardened to a hardness of 64 HRC – ensures lasting edge sharpness when cutting extra-fine left-hand threads on large diameters
- Ultra-fine pitch of 1 mm at a diameter of 25 mm – extremely high thread count ensures maximum connection strength and leak tightness
- Accuracy class 6g according to DIN 22 568 – general-purpose medium fit with controlled clearance for precision applications
- Solid round construction – solid body construction eliminates deformation when machining large-diameter shafts
This die is used in high-pressure hydraulics, rotating machinery, and wherever self-locking protection with the absolute maximum strength is required. Class 6g allows easy assembly with 6H left-hand nuts. Professional workshops use the M25x1 left-hand die in the production of high-pressure hydraulic components, precision spindles rotating clockwise, and wherever the priority is the maximum number of thread turns with protection against loosening in large-diameter assemblies.
Frequently asked questions
The combination of an extra-fine pitch of 1 mm and a left-hand thread at a diameter of 25 mm is used in high-pressure hydraulic systems, precision spindles rotating clockwise, and wherever maximum leak tightness, strength, and protection against loosening are required with limited thread engagement length.
The outside diameter of the rod should be 24.82-24.92 mm in accordance with tolerance 6g per DIN 22 568. Chamfer the end of the rod at 45° over a length of 6 mm before starting to cut the left-hand thread.
Chamfer the end of the rod at 45°, secure the workpiece in a vise or chuck that prevents vibration, and keep the die perpendicular to the axis. Turn counterclockwise instead of clockwise, back off half a turn after each full turn, and apply plenty of specialized threading oil.
