Die M76x4 HSS DIN 22 568 – coarse thread for structures of extreme dimensions
The M76x4 die is a specialized round tool made of high-speed steel (HSS) with a hardness of 64 HRC, designed for cutting external metric threads with a very large diameter of 76 mm and a coarse pitch of 4 mm. The large thread pitch enables very fast cutting while maintaining sufficient mechanical strength in steel structures of the largest dimensions. Compliance with DIN 22 568 and a 6g tolerance ensure a proper fit with 6H nuts in heavy industry applications. This tool is used in specialized workshops serving the power industry, shipyards, and steel structures of extreme dimensions.
Key advantages of the M76x4 coarse-pitch die
- Coarse pitch of 4 mm for maximum efficiency – the largest pitch increases threading speed by as much as 50-60 percent compared with a 2 mm pitch while maintaining adequate strength
- Diameter of 76 mm for the largest structures – the size makes the tool suitable for main turbine shafts, rods of large cylinders, and foundation components
- HSS with a hardness of 64 HRC – provides exceptional wear resistance when cutting threads of the largest diameters in structural steels up to 800 MPa
- 6g tolerance according to ISO – standard fit with normal clearance allows nuts to be installed without binding despite the extreme dimensions
- Solid round construction – one-piece construction provides the maximum rigidity absolutely essential when cutting coarse-pitch threads of extreme diameters
The M76x4 die is a tool for the most specialized industrial workshops serving the power industry, shipyards, mining, and steel structures of extreme dimensions. It is suitable for cutting threads on the largest shafts, pins, and foundation rods. Due to the dimensions, threading requires a powered drive, very rigid holders, and highly qualified operators.
Frequently asked questions
Prepare the rod (diameter 75.2-75.3 mm) with a 45° chamfer. Due to the extreme dimensions, a powered drive is mandatory – a lathe or a specialized threading machine. Keep the die perpendicular using this cycle: two turns forward, one reverse movement of half a turn. Use very rigid workholding.
With such a large diameter and coarse pitch, use intensive lubrication with threading oils or a cooling and lubricating emulsion. Apply generously before starting and every 2-3 turns. Due to the high cutting forces, lubricant must be present at all times – consider an automatic lubrication system on the machine.
At extreme dimensions, problems are particularly dangerous. Stop the drive immediately and back the die off in reverse. Check the rod diameter carefully – at 76 mm, even a deviation of 0.5 mm can cause problems. Clean the flutes, verify lubrication, and resume with maximum caution and more frequent reversing (every 1.5 turn).
