Die M56X4 HSS DIN 22568 – very large-diameter metric fine threads
For cutting external threads with a diameter of 56 mm and a fine pitch of 4 mm on large shafts and structural components. M56X4 metric die made of high-speed steel (HSS) hardened to 64 HRC in accordance with DIN 22568, provides precision and durability in heavy industry. The tool is designed for manufacturing plants, industrial workshops, and maintenance departments servicing large steel structures.
Key benefits of the M56X4 threading die
- HSS steel hardness of 64 HRC – long service life without loss of sharpness when threading very large cross sections under industrial conditions
- Fine thread with a 4 mm pitch – the German Institute for Standardization (Deutsches Institut für Normung) standard provides increased joint strength compared with the standard M56X5.5 thread
- Tolerance class 6g according to DIN 22568 – general-purpose clearance fit for very large diameters in machinery applications
- Range of machinable materials – effective thread cutting in steels with tensile strengths up to 800 MPa and gray cast iron
- Round design – solid body construction ensures uniform cutting forces at very large dimensions
Heavy industry specialists use the M56X4 round die in the production of main shafts, turbine components, and steel structures in the power generation industry. The tool is suitable for the shipbuilding and mining industries, as well as repairs to large industrial machines. Choose a tool designed for demanding applications involving large components.
Frequently asked questions
Chamfer the edge of the shaft at 45°, secure the workpiece in a lathe chuck or specialized fixture, and guide the die perpendicular to the axis. Due to the very large diameter, operation by two people or the use of a powered die holder is recommended. Apply lubricant generously after each full turn.
The designation 6g specifies a general-purpose level of accuracy with assembly clearance, allowing trouble-free nut installation. It is the most common standard in heavy industry and large machinery structures.
The tool is designed for machining structural steels with a maximum tensile strength of 800 MPa and gray cast iron. The maximum hardness of the workpiece material is 40 HRC.
