M4 Thread Former DIN 2174 (DIN 371) Form C HSS-Co TiN Coating 6HX, 13mm Thread Length - TECWERK

Take advantage of the combination of precise cold forming, durable TiN surface protection and an industry‑standard 6HX tolerance to ensure reliable M4 thread production in ductile metals; order the tool directly via Metav Werkzeuge or consult the specialists for application support.

Thread Former M4 (DIN 2174 / DIN 371) — HSS‑Co, TiN‑coated, Form C — TECWERK

The Thread Former M4 (DIN 2174 / DIN 371) is a carbide‑reinforced HSS‑Co forming tool designed for producing ISO metric M4 threads in ductile non‑ferrous metals and steels, suitable for both through and blind holes.

• HSS‑Co construction for high toughness
• TiN coating for enhanced wear resistance
• Form C straight‑fluted, flank‑relieved geometry
• Tolerance 6HX for ISO metric M4 threads

Faster, chip‑free thread production that improves component strength

Cold thread forming replaces material removal with plastic displacement to create stronger root profiles and a continuous grain flow in the parent material. The Form C geometry with straight flutes and flank‑relieved surfaces reduces forming torque and radial forces, which supports more consistent cycle times on production lines. By avoiding chips, rework and coolant disposal are reduced, resulting in a more efficient process for medium‑run manufacturing environments.

Built for longevity and dimensional accuracy in demanding use

The combination of HSS‑Co substrate and TiN surface treatment provides a balance of toughness and surface hardness that extends tool life under intermittent loads. The 6HX tolerance ensures the formed ISO thread meets common assembly requirements without additional rework, while the straight‑fluted, flank‑relieved design aids in controlled cold flow during forming. These features help maintain repeatable joint performance and reduce downtime for tool changes.

Practical application notes for workshop and production planning

Suitable workpiece materials include non‑ferrous metals and steels with at least 10% elongation, where the forming action achieves optimum results. The tool offers a 13 mm thread length and a 4.5 mm shank, facilitating secure clamping in standard toolholders and compatibility with common spindle chucks. For blind‑hole forming ensure correct pilot hole size and adequate material ductility; for through holes, straightforward feed and secure part clamping typically produce the best outcomes. For detailed process parameters and pilot‑hole recommendations, Metav Werkzeuge provides application guidance.

FAQ

How does a thread former differ from a cutting tap?
A thread former creates threads by plastic deformation rather than cutting; the Thread Former M4 (DIN 2174 / DIN 371) from TECWERK forms chip‑free threads that typically have improved root strength and surface finish compared with cut threads.

Which materials are suitable for this forming tool?
The TECWERK M4 thread former is intended for non‑ferrous metals and steels with at least 10% elongation, where ductility allows controlled material flow during forming.

Can the tool be used for blind holes as well as through holes?
Yes, the Form C geometry and flank relief permit reliable forming in both through and blind holes; pilot‑hole dimension and material ductility should be observed to avoid excessive forming forces.

What does the 6HX tolerance mean for assembly?
Tolerance 6HX specifies the intended fit for ISO metric threads; with the TECWERK forming tool this results in a standardised internal thread suitable for common bolts and fasteners without additional machining.

What are the critical dimensions for holder selection?
Relevant dimensions are the 13 mm thread length and the 4.5 mm shank; these values determine clamping requirements and the clearance needed in the toolholder or chuck.
