Die M8x0.5 WS DIN 22568 – ultrafine threads for special applications
For producing external threads with a diameter of 8 mm and an ultrafine pitch of 0.5 mm on components requiring maximum joint precision and sealing. Metric die M8x0.5 WS made of high-speed steel (HSS) hardened to 64 HRC in accordance with DIN 22568 (Deutsches Institut für Normung – German Institute for Standardization), delivers repeatable results in precision engineering. The tool is intended for specialized toolrooms, micromachining shops, and facilities manufacturing precision equipment from structural steel.
Distinctive features of the M8x0.5 WS threading die
- HSS hardened to 64 HRC – maximum cutting edge life essential for cutting ultra-fine threads on small cross sections
- Ultra-fine thread with a 0.5 mm pitch – the greatest number of threads provides maximum joint strength and sealing for a diameter of 8 mm
- Tolerance class 6g according to DIN 22568 – general-purpose clearance fit for precision threaded joints in special applications
- Material compatibility – effective thread cutting in steels with tensile strengths up to 800 MPa and in aluminum alloys
- WS design – specialized body design ensuring stability when cutting ultrafine threads
The M8x0.5 WS round die is used in the manufacture of measuring instruments, inspection equipment, and scientific instruments. The tool is used in precision optics, industrial electronics, and wherever maximum sealing and dimensional accuracy are required in small diameters. Choose a solution for ultraprecise special applications.
Frequently asked questions
This tool is designed for threading structural steels with a maximum tensile strength of 800 MPa, as well as aluminum and brass alloys. Do not use it in materials with hardness above 40 HRC.
Chamfer the end of the rod at 45°, clamp the component to prevent vibration, and guide the die exactly perpendicular to the axis. Apply minimal pressure, reverse half a turn after each full turn, and use a specialized lubricant for precision machining.
Tolerance 6g specifies a general-purpose precision class with assembly clearance, allowing nuts to be screwed on without difficulty. It is the most popular standard in precision engineering and instrumentation applications.
