Die M26x1.5 left-hand HSS DIN 22 568 – left-hand fine threading, designation 800

The M26x1.5 left-hand HSS 800 metric die is a professional round die for cutting external left-hand threads with a diameter of 26 mm and a fine pitch of 1.5 mm. Made from high-speed steel (HSS) hardened to 64 HRC with designation 800, compliant with DIN 22 568, it guarantees high dimensional accuracy in demanding applications. The M26x1.5 left-hand HSS 800 threading die is designed for use in structural steels with a maximum tensile strength of 800 MPa and nonferrous alloys.

Main advantages of the M26x1.5 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 fine thread with a 1.5 mm pitch – dual protection through the left-hand direction and increased number of thread turns for maximum strength
  • Hardened to a hardness of 64 HRC – ensures lasting edge sharpness when cutting left-hand fine threads
  • Accuracy class 6g according to DIN 22 568 – general-purpose medium fit with controlled clearance for mechanical applications
  • Solid round construction – solid body construction guarantees stability when machining medium-diameter shafts

This die is used in rotating machinery, industrial transmissions, and wherever protection against loosening and high strength are required. Class 6g ensures compatibility with 6H left-hand nuts. Professional workshops use the M26x1.5 left-hand HSS 800 die in the production of industrial spindles and transmission components rotating clockwise, and in repairs to machines with specific directions of rotation requiring maximum strength and protection against loosening.

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 outside diameter of the rod should be 25.80-25.92 mm in accordance with tolerance 6g per DIN 22 568. Chamfer the end of the rod at 45° over a length of 6 mm before starting to cut the left-hand thread.

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.
