Die M18x1.25 left-hand HSS DIN 22 568 – left-hand fine threading, designation 800
The M18x1.25 left-hand HSS 800 threading die is an advanced round die for cutting external left-hand threads with a diameter of 18 mm and a fine pitch of 1.25 mm. Manufactured from high-speed steel (HSS) hardened to a hardness of 64 HRC with designation 800 in accordance with DIN 22 568, it ensures high dimensional accuracy in demanding applications. The M18x1.25 left-hand HSS 800 metric die is designed for machining structural steels with a maximum tensile strength of 800 MPa.
Main advantages of the M18x1.25 left-hand HSS 800 round die
- HSS 800 designation – material specification indicating a maximum workpiece material tensile strength of up to 800 MPa
- Left-hand metric fine thread – dual protection through the left-hand direction and increased number of thread turns for high strength
- Hardened to a hardness of 64 HRC – increased abrasion resistance when cutting fine left-hand threads
- Fine pitch of 1.25 mm at a diameter of 18 mm – optimal thread density ensures strength and resistance to varying loads
- Accuracy class 6g according to DIN 22 568 – standard fit with controlled clearance for general-purpose applications
This die is used in the machinery industry, hydraulics, and wherever protection against loosening is required. Class 6g ensures compatibility with 6H left-hand nuts. Professional workshops use the M18x1.25 left-hand HSS 800 die in the production of transmission components rotating clockwise, hydraulic components, and wherever protection against self-loosening is required together with increased strength in working machinery exposed to intense vibration.
Frequently asked questions
The designation 800 indicates the maximum tensile strength of the workpiece material in megapascals. The HSS 800 die is suitable for structural steels with a tensile strength of up to 800 MPa, corresponding to a maximum hardness of 37 HRC for safe machining.
The rod diameter should be 17.77-17.88 mm in accordance with tolerance 6g per DIN 22 568. Chamfer the end of the rod at 45° over a length of 4-5 mm to facilitate engagement of the first cutting edges of the left-hand die.
Yes, die stocks are universal and suitable for both right-hand and left-hand threads. The only difference is the direction of rotation during threading - a left-hand die is turned counterclockwise instead of clockwise, using the same half-turn backing-off technique.
