Die M4 left-hand HSS – a specialized tool for precision left-hand threaded connections
The M4 left-hand HSS die is a tool for cutting left-hand external threads with a diameter of 4 mm and a pitch of 0.7 mm. Its dimensions of 20 x 5 mm make it ideal for working with small-section components, while the high-speed steel (HSS) material ensures long-lasting cutting edge sharpness.
Key properties of the M4 left-hand die for precision work
- Left-hand geometry (LH) produces threads that resist loosening on their own in rotating mechanisms and equipment subjected to vibration
- High-grade HSS steel allows machining of steel, aluminum and brass with a tensile strength of up to 800 MPa
- Compact dimensions of 20 x 5 mm allow easy operation in confined spaces and with delicate components
- DIN 22 568 standard with 6g tolerance confirms dimensional conformity and proper mating with standard nuts
- Form B chamfered lead-in ensures easy thread starting and clean formation of the first threads
The M4 left-hand die is suitable for manufacturing locking screws for optical equipment, fasteners for industrial automation, medical device components, and precision mechanical parts. Essential for repairs and production where the operating direction requires a reverse thread. Invest in precision – M4 LH HSS die will ensure repeatability and quality in every project requiring a small left-hand thread.
Frequently asked questions
The HSS tool can machine carbon and stainless steels, aluminum, brass, and bronze. The maximum material strength should not exceed 800 MPa.
Left-hand threads protect joints against loosening caused by vibration or rotation. In precision mechanisms, this is critical for safety and durability.
Position the tool perpendicular to the rod axis and turn it counterclockwise. Lubrication and reversing every half turn to break chips are recommended.
