M8x1.25mm Machine Tap DIN 371B HSS-Co TiN Coated ISO2 6H, Milled Flutes - TECWERK

The combination of HSS‑Co construction, TiN coating and straight flutes ensures precise, long‑lasting M8×1.25 threads in through‑holes, improving cycle stability and reducing rework; procure the TECWERK machine tap directly via Metav Werkzeuge or consult our specialists for application advice.

TECWERK Machine Tap DIN 371B M8×1.25 HSS‑Co TiN 6H – straight‑flute machine tap with TiN coating

The TECWERK Machine Tap DIN 371B M8×1.25 is a straight‑flute, TiN‑coated machine tap intended for producing ISO metric through‑threads in medium‑strength steels.

• HSS‑Co construction for improved tool life
• TiN coating reduces friction and wear
• Straight flutes (Form B) for through‑hole threading
• ISO metric M8×1.25 with 6H tolerance

Consistent thread quality for production use

The TECWERK Machine Tap DIN 371B M8×1.25 is manufactured to DIN 371B and DIN 13 Blatt 1 standards and delivers an ISO metric thread with 6H tolerance. This combination provides repeatable dimensional accuracy and a predefined tolerance class that supports interchangeability of threaded parts in assemblies. For production environments, the result is reduced inspection effort and fewer rejected components, because the thread form and flank run‑out are controlled within the expected industrial limits.

Longer service life through advanced materials and coating

Constructed from HSS‑Co, the tap offers elevated red hardness and toughness compared with standard high‑speed steel, which helps resist wear under higher cutting temperatures. The TiN coating further lowers friction at the cutting edge and improves wear resistance, extending tool life and lowering the frequency of changeovers. In practice this means fewer tool changes per shift and a better cost‑per‑thread ratio when machining comparable steels.

Optimised geometry for reliable chip evacuation and thread form

The straight flutes (Form B) and flanks ground geometry ensure consistent chip flow when producing through threads; the incorporated cutting chamfer (Schälanschnitt) is specifically configured for through‑hole applications to reduce thread burr and promote stable chip removal. A centred shank Ø 8 mm enables secure clamping in standard collets and reduces vibration, which supports a clean thread profile and lessens the need for secondary finishing.

Integrates into workshop workflows and covers common materials

Engineered for steels up to 1000 N/mm², this tap suits a broad range of general engineering and maintenance tasks. The combination of geometry, material and coating makes it suitable for repetitive series work where uptime and consistency are priorities. Linking procurement through Metav Werkzeuge provides access to stock control, expert selection advice and a dependable supply chain that supports continuous production.

FAQ

Is this tap suitable for through‑hole threading in steel up to 1000 N/mm²?
Yes. The TECWERK Machine Tap DIN 371B M8×1.25 (SKU 2000867304NW) is specified for steels with tensile strength up to 1000 N/mm², making it appropriate for common structural and engineering steels.

What advantages does the TiN coating provide?
The TiN coating on this tap reduces friction, increases surface hardness and improves wear resistance, which helps maintain sharpness and extends the effective life of the HSS‑Co tool under continuous use.

Which toolholders or chucks are compatible with the shank?
The shank Ø 8 mm is compatible with standard collets and drill chucks used in machine tapping heads and automatic machines, enabling straightforward integration into typical workshop tooling systems.

What does the 6H tolerance signify for internal threads?
A 6H tolerance (ISO2) designates the internal thread tolerance class and indicates a standard fit with nominal clearance for bolts and screws of corresponding tolerance, ensuring reliable assembly without excessive play or undue interference.

Is this tap recommended for blind holes or internal thread roots?
This variant is designed with a cutting chamfer optimised for through‑threads; for blind holes or where thread‑runout must be minimised at the root, a tap with a different chamfer or spiral flute geometry should be considered.
