Die M28x1.5 left-hand HSS – left-hand fine threading in accordance with DIN 22 568
The M28x1.5 left-hand metric die is a specialized round die for cutting external left-hand threads with a diameter of 28 mm and a fine pitch of 1.5 mm. Manufactured from high-speed steel (HSS) hardened to 64 HRC in accordance with DIN 22 568, it guarantees high dimensional accuracy and long service life in professional applications. The M28x1.5 left-hand threading die is designed for cutting threads in structural steels with a maximum tensile strength of 800 MPa.
Key advantages of the M28x1.5 left-hand round die
- HSS steel hardened to 64 HRC – ensures long-lasting sharpness during intensive cutting of left-hand threads in structural steels
- Accuracy class 6g according to DIN 22 568 – standard medium fit with controlled clearance for universal mechanical applications, ensuring easy assembly with 6H nuts
- Solid round design – one-piece body construction increases stability and eliminates deformation when cutting threads on rotating shafts
- Left-hand fine thread with a pitch of 1.5 mm – prevents spontaneous unscrewing in clockwise-rotating components, while higher thread density increases connection strength
- Material range up to 800 MPa – efficient thread cutting in structural steels, aluminum, and brass
The die is used in toolrooms, machine shops, and precision mechanics. Tolerance class 6g provides standard clearance in the connection, eliminating assembly problems with left-hand threaded connections. Professional workshops use the M28x1.5 left-hand die to cut threads on grinding machine spindles, industrial mill components, and clockwise-rotating machines requiring protection against loosening.
Frequently asked questions
Class 6g defines a medium degree of accuracy with controlled axial clearance, allowing easy assembly with 6H left-hand nuts. It is a universal standard for mechanical connections in industry, providing a suitable balance between ease of assembly and leak tightness of the threaded connection.
The die is intended for structural steels with a tensile strength of up to 800 MPa and nonferrous metals such as aluminum and brass. The maximum workpiece material hardness is 37 HRC; above this value, HSSE dies are recommended.
Chamfer the end of the rod with a diameter of 27.80-27.92 mm at an angle of 45° over a length of 7 mm and secure the workpiece firmly in a vise. Guide the left-hand die perpendicular to the axis while turning it counterclockwise, reverse half a turn every two full revolutions, and apply generous lubrication with threading oil for structural steel.
