Take advantage of a high-strength HSS-Co construction combined with a TiN coating to extend tool life and maintain consistent M8 thread quality. The design supports both through and blind holes with a 22 mm thread length and an 8 mm shank for straightforward installation; order directly via Metav Werkzeuge for reliable supply and expert advice.

Thread former DIN 2174 (DIN 371) M8 Form C – HSS‑Co, TiN‑coated (TECWERK)

The Thread former DIN 2174 (DIN 371) M8 Form C is a precision forming tap engineered for producing M8 metric ISO threads in ductile metals and steels, suitable for both through and blind hole applications.

• HSS-Co for increased toughness and wear resistance
• TiN coating for longer tool life and reduced friction
• Forming tap for chipless thread generation
• Suitable for through and blind holes

High-performance forming for consistent production

The HSS‑Co base material delivers elevated toughness and thermal resistance compared with standard high-speed steels, which supports continuous operation under demanding conditions. As a forming tap, the tool creates threads by cold forming rather than cutting; this produces work-hardened thread flanks and eliminates chip management, improving cycle reliability. The TiN surface treatment further reduces friction during forming, extending service intervals and lowering overall process costs while maintaining consistent M8 thread dimensions.

Material compatibility that reduces rework

Designed for use in non‑ferrous metals and steels with ≥10% elongation, the tool reliably forms ISO metric threads without material fracturing when the component ductility is sufficient. The forming process increases root strength of the thread and avoids burr formation typical of cutting taps, thereby reducing secondary finishing. The 6HX tolerance field provides a practical fit class for many assembly situations, offering predictable mating behaviour and easing assembly tolerances for production runs.

Design details that improve thread quality and control forces

The straight‑fluted geometry and flanks undercut lower forming forces and guide material flow into the thread profile, yielding cleaner, more accurate threads across the full 22 mm forming length. A shank diameter of Ø 8 mm ensures compatibility with standard toolholders and reduces vibration during operation. These design choices combine to reduce spindle load and heat build-up, which supports longer tool life and steadier cycle times in serial production.

Practical handling and inspection guidance

For best results, ensure correct hole preparation and lubrication suited to cold forming processes: a properly sized pilot hole and an appropriate forming lubricant will reduce torque peaks and prevent premature tool wear. Regular inspection of formed threads for profile conformity and functional fit keeps assemblies within specification; use calibrated gauges where repeatability is critical. The robust construction of this roll tap minimises downtime and, when paired with Metav Werkzeuge’s supply reliability, supports uninterrupted workshop throughput.

FAQ

What materials can this forming tap process effectively?
The thread former is intended for non‑ferrous metals and steels with ≥10% elongation, where the cold forming process can displace material without fracturing the workpiece.

How does a forming tap differ from a cutting tap for M8 threads?
A forming tap produces threads by material displacement rather than chip removal; the Thread former DIN 2174 (DIN 371) M8 Form C (TECWERK, SKU 2000867620NW) yields stronger, burr‑free threads and eliminates chip handling.

What are the benefits of the TiN coating on this tool?
The TiN coating lowers friction and improves wear resistance during forming, which extends the service life of the tool and stabilises process performance.

Which hole preparation is recommended before using this forming tap?
Use the recommended pilot hole diameter for M8 forming taps and apply a suitable forming lubricant to reduce torque and improve material flow; correct preparation protects the tool and the workpiece.

What does the tolerance field 6HX mean for assembly?
The 6HX tolerance provides a practical clearance class for metric ISO threads, offering consistent fit and simplifying assembly checks in production environments.
