M40x1.5 left-hand HSS die DIN 22 568 – left-hand ultra-fine threading in very large cross sections
The M40x1.5 left-hand threading die is a specialized round die for cutting external left-hand threads with a diameter of 40 mm and an ultra-fine pitch of 1.5 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 M40x1.5 left-hand metric die is designed for machining structural steels with a tensile strength of up to 800 MPa and special materials.
Main advantages of the M40x1.5 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 64 HRC – provides long-lasting sharpness when cutting ultra-fine left-hand threads at very large diameters
- Ultra-fine pitch of 1.5 mm at a diameter of 40 mm – extremely high thread count ensures maximum connection strength and leak tightness
- Fit 6g according to DIN 22 568 – a standard class for applications in very large machinery
- Solid round construction – the solid body construction eliminates deformation when machining shafts with very large diameters
The die is used in the marine industry, large-scale power generation, and the production of very large machinery. Class 6g allows easy assembly with 6H left-hand nuts. Professional manufacturing facilities use the M40x1.5 left-hand die in the construction of marine engines, power generation turbine units, and wherever protection against loosening is required with the absolute maximum number of threads and very large diameters under critical dynamic loads.
Frequently asked questions
The combination of an ultra-fine pitch of 1.5 mm and a left-hand thread at a diameter of 40 mm is used in marine engines with the highest power outputs, clockwise-rotating power generation turbine units, and wherever maximum leak tightness, strength, and protection against loosening are required at very large diameters.
The outside diameter of the rod should be 39.80-39.92 mm in accordance with tolerance 6g per DIN 22 568. Chamfer the end of the rod at 45° over a length of 10 mm before starting to cut the left-hand thread.
No, the very large diameter of 40 mm requires a high-torque machine drive. A holder with axial compensation and secure clamping that prevents any vibration during left-hand threading are absolutely essential.
