TECWERK cutting die M5 x 0.8, Form B (HSS, left‑hand)

A cutting die M5 x 0.8 Form B for producing left‑hand metric ISO threads in workshop and maintenance environments, suitable for steels up to approx. 800 N/mm²

• HSS high‑speed steel for wear resistance
• Metric ISO thread M5 x 0.8, tolerance 6g
• Left‑hand cutting, closed pre‑slit Form B
• Suitable for steels up to circa 800 N/mm²

Consistent thread quality for serial production

The TECWERK cutting die M5 x 0.8 is engineered to deliver reproducible results in repetitive operations. Made from HSS and manufactured to DIN EN 22568, the tool produces metric ISO threads with a 6g tolerance, ensuring parts meet standardised fit requirements. For production planners this translates into fewer rejects and predictable interchangeability. The technical specification of the thread (M5 x 0.8) and the standard compliance support quality control and simplify documentation across procurement and inspection processes.

Robust geometry that reduces downtime

The closed, pre‑slit Form B geometry and a nominal height of 7 mm combine to improve chip control and increase tool life under typical workshop stresses. The pre‑slit design provides controlled chip breaking and easier ejection, which helps avoid thread damage when cutting in tougher materials. Because the die is specified for steels up to approx. 800 N/mm², maintenance teams can rely on the component for repair work and small‑batch production without frequent replacement, improving overall equipment effectiveness and reducing maintenance frequency.

Practical integration and application benefits

The left‑hand cutting orientation is ideal where left‑hand threads are required for mechanical assemblies or for repair tasks on components already manufactured with reversed threads. The compact form and recognised threading standard mean the die fits common die holders and thread‑cutting fixtures, enabling quick set‑up and minimal changeover time. For purchasing managers and workshop supervisors, the combination of HSS construction and standard conformity offers a cost‑effective balance of durability and interchangeability, supporting efficient stock management and reliable on‑the‑job performance.

FAQ

How does Form B differ from other die forms?
Form B is a closed die design with a pre‑slit section that combines precise thread flanks with controlled chip breaking; this makes the TECWERK die particularly suitable for standardised metric ISO thread production where chip control and surface finish are important.

Can this die be used on hardened or alloyed steels?
The die is specified for steels up to approx. 800 N/mm²; use on substantially harder or specially alloyed steels may accelerate wear and is not recommended without testing.

Is the thread compatible with standard die holders?
Yes, the die conforms to metric ISO threading conventions and can be mounted in commonly used die holders and fixtures for thread cutting and repair.

Does left‑hand cutting affect machining direction?
Left‑hand cutting produces threads with reverse orientation; users should ensure the application requires a left‑hand thread and select compatible holders and lathes or manual turning direction accordingly.

What maintenance extends the life of the die?
Regular cleaning of chips, appropriate cutting lubrication and avoiding excessive feed rates will prolong service life and maintain consistent thread quality when using the TECWERK die.
