Round die Form B M3×0.5 mm HSS, left‑hand cutting (6g) – TECWERK

A Round die Form B M3×0.5 mm designed for cutting left‑hand metric ISO threads to DIN 13, suitable for external threading in workshop and maintenance contexts.

• HSS high‑speed steel construction
• Left‑hand cutting for reverse threads
• Metric ISO thread to DIN 13, tolerance 6g
• Closed, pre‑slotted Form B design

Durable cutting performance for repeatable threads

The HSS construction provides a robust cutting edge that maintains form under repeated use, delivering consistent thread geometry and reducing rework. As a compact external threading tool, the round die supports rapid setup in common die holders and is particularly suited to small‑diameter applications such as machine maintenance and prototype assembly. The design emphasis is on longevity and repeatable results, so production flow remains uninterrupted and inspection findings stay within tolerance.

Controlled tolerance and left‑hand thread capability

The 6g tolerance class, specified to DIN 13, ensures threads meet standard external thread clearances required in metric assemblies. The Form B shape, which is closed yet pre‑slotted, guarantees stability during cutting while allowing slight material relief via the slot for consistent chip evacuation. The left‑hand cutting orientation produces reverse threads where required by design, eliminating the need for additional fixturing changes and supporting specialised assemblies.

Application range and material suitability

Rated for use with steels up to 800 N/mm² tensile strength, the tool is built to handle most common workshop steels without accelerated wear. With a thickness of 5 mm, the die offers a balance between stiffness and accessibility for small external thread runs. This combination supports reliable results in maintenance, fabrication and small‑batch production, providing the practical advantage of a standardised threading solution that integrates with existing tooling systems.

Practical handling and workshop integration

The compact geometry of the die, together with its pre‑slotted Form B configuration, simplifies alignment and start‑up for external threads, helping to reduce set‑up time. When used in a compatible die stock it enables steady, concentric engagement and controlled cutting forces. For operators and procurement teams seeking a dependable external threading option, the component represents a technically sound choice that aligns with established metric thread standards.

FAQ

What materials can be machined with this die?
The die is suitable for machining steels with tensile strengths up to approx. 800 N/mm²; the TECWERK HSS construction provides the necessary wear resistance for such applications.

Is the die suitable for left‑hand threading only?
Yes, the tool is a left‑hand cutting round die, intended to produce reverse (left‑hand) external threads in metric ISO form.

What does Form B and pre‑slotted mean for performance?
Form B indicates a closed die geometry that, being pre‑slotted, allows controlled chip relief and stable engagement for repeatable external threads.

Which standard does the thread conform to?
Threads produced conform to metric ISO requirements as specified by DIN 13, with a tolerance class of 6g for external threads.
