Die M30X2.5 left-hand HSS – left-hand threading at large diameters DIN 22 568
The M30X2.5 left-hand metric die is a specialized tool for cutting external left-hand threads with a diameter of 30 mm and a pitch of 2.5 mm. Made from high-speed steel (HSS) hardened to 64 HRC, compliant with DIN 22 568, it provides the highest dimensional precision in applications requiring left-hand threads. The M30X2.5 left-hand round die is designed for use in structural steels with a tensile strength of up to 800 MPa and in nonferrous metals.
Main advantages of the M30X2.5 left-hand HSS threading die
- Left-hand thread (left-hand) – specialized use in mechanisms that prevent self-loosening during clockwise rotation
- HSS steel, 64 HRC – provides lasting sharpness when cutting threads at large diameters
- Pitch 2.5 mm – suitable for general use at a diameter of 30 mm, providing adequate mechanical strength
- Medium tolerance 6g according to DIN 22 568 – standard clearance fit with controlled clearance for general-purpose applications
- Solid round construction – the solid body ensures stability when machining large shafts
The tool is used in rotating machinery where the direction of rotation would cause standard right-hand threads to loosen, in the grain milling industry, and wherever self-locking connections are required. Professional workshops use the M30X2.5 left-hand die in machining shafts that rotate clockwise, producing mill components, and in rotating machinery requiring threads secured against loosening.
Frequently asked questions
Left-hand threads are used in components that rotate clockwise, where centrifugal force or torque could loosen a standard right-hand thread. Typical applications include mill wheels, grinder spindles, bicycle pedals, and connections in rotating machinery.
Left-hand dies have a left-hand (Left Hand) designation in the product code and an arrow or inscription on the body. The thread is cut by turning the die to the left (counterclockwise), opposite to the direction used with a standard tool.
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.
