M55x1.5 HSS DIN 22 568 die – metric fine threading of large diameters
The M55x1.5 die combines large dimensions with a metric fine thread, creating a specialized tool for demanding industrial applications. Made of high-speed steel (HSS) with a hardness of 64 HRC, it enables precise cutting of external threads with a diameter of 55 mm and a fine pitch of 1.5 mm. This pitch, significantly smaller than the standard pitch for this diameter, provides increased thread contact area, better sealing, and greater resistance to vibration loads. Compliance with DIN 22 568 and the 6g tolerance ensure proper mating with 6H nuts in large precision mechanisms requiring the highest reliability.
Key features of the M55x1.5 die for special applications
- Metric fine thread with a pitch of 1.5 mm at a diameter of 55 mm – an unusual combination providing exceptional fatigue strength and joint sealing in applications exposed to extreme dynamic loads
- HSS material, 64 HRC – the high hardness of high-speed steel enables prolonged thread cutting in structural steels with a tensile strength Rm of up to 800 MPa without cutting edge degradation
- Diameter of 55 mm for large structures – its size makes the tool suitable for working on precision shafts, critical studs, and turbine components in the power generation industry
- Tolerance class 6g – medium accuracy grade with controlled clearance ensures a proper fit in mechanisms requiring dimensional stability at large diameters
- Solid round design – solid construction eliminates cumulative errors and provides the maximum rigidity required when threading large diameters with a fine pitch
This tool is designed for specialized workshops serving industries with the most demanding quality and safety requirements. The M55x1.5 die is used in aerospace, power generation, the nuclear industry, and critical structures where standard threads do not meet strength and reliability requirements. Due to the combination of a large diameter and a fine pitch, threading requires careful material preparation, secure clamping, suitable highly rigid die stocks, and high-quality cutting fluids to minimize cutting forces and temperature.
Frequently asked questions
Metric fine threads at large diameters are used in applications requiring maximum vibration resistance, the highest sealing performance, or in precision adjustment mechanisms. A greater number of threads per unit length significantly improves strength characteristics under fluctuating and high loads.
The initial diameter should be between 54.6 and 54.7 mm. For a large-diameter metric fine thread, material preparation tolerances are critical – even small deviations can drastically affect profile quality and the torque required for cutting.
Large-diameter fine threads are used in the aerospace industry (critical landing gear and engine components), power generation (high-speed turbines, generator shafts), the nuclear industry (safety-critical components), and precision machinery requiring the highest reliability of threaded connections under extreme loads.
