Die M20x1.25 HSS DIN 22 568 – precision tool for metric fine threads
The M20x1.25 die is a professional round tool made of high-speed steel (HSS) with a hardness of 64 HRC, designed for cutting external metric fine threads with a diameter of 20 mm and a pitch of 1.25 mm. Compliant with DIN 22 568, it ensures precise thread cutting to tolerance 6g – a standard fit class providing normal clearance with 6H nuts. The round, solid construction guarantees a stable cutting process in structural steels with a tensile strength of up to 800 MPa, making it ideal for machine shops and maintenance departments.
Main advantages of the M20x1.25 metric fine thread die
- Fine thread, 1.25 mm – a smaller pitch than a standard thread provides greater resistance to dynamic loads and vibration, ideal for the automotive and machinery industries
- HSS with a hardness of 64 HRC – guarantees long tool life when cutting threads in structural steels, free-cutting steels, and materials with a tensile strength of up to 800 MPa
- 6g tolerance according to ISO – a standard medium fit with normal clearance allows easy assembly of 6H nuts without the risk of components binding
- Solid round construction – a solid die without separate segments eliminates the risk of loss of geometry and ensures repeatable thread dimensions
- Compliance with DIN 22 568 – standardized external dimensions simplify tool holder selection and guarantee compatibility with clamping systems
The M20x1.25 die is a choice for professionals producing one-off and small batches of threaded components requiring increased connection strength. It is ideal for threading shafts, mounting pins, and threaded studs in precision engineering. Use with threading lubricants (e.g., threading oils) is recommended to extend cutting edge life and achieve a smooth thread surface.
Frequently asked questions
The M20x1.25 thread has a fine pitch of 1.25 mm instead of the standard 2.5 mm. The smaller pitch increases resistance to vibration loads and provides more precise tightening adjustment in automotive and machinery applications.
The high-speed steel (HSS) tool effectively cuts threads in materials with a maximum hardness of 37 HRC. It performs well in structural steels with a tensile strength of up to 800 MPa and nonferrous metals such as aluminum and brass.
Standard round die stocks with three-point clamping fit this die. External dimensions compliant with DIN 22 568 guarantee versatile mounting in manual die stocks with handles and machine holders.
