Take advantage of a robust combination of HSS‑Co construction, right‑hand spiral geometry and ISO tolerance to ensure consistent thread quality and reduced rework in serial production; order directly via Metav Werkzeuge or consult the Metav specialists for application-specific recommendations.

Machine thread tap DIN 376C M16×2 HSS‑Co 6H – TECWERK

Machine thread tap DIN 376C M16×2 HSS‑Co 6H is a spiral‑fluted, right‑hand machine tap designed for producing metric ISO blind threads in medium‑strength steels.

• HSS‑Co for increased heat resistance
• Right‑hand spiral 40° for efficient chip evacuation
• Tolerance ISO2 (6H) for precise metric threads
• Suitable for blind holes in steels up to 900 N/mm²

High‑precision threads with durable cobalt HSS

The machine tap is manufactured from HSS‑Co, a cobalt‑alloyed high‑speed steel that improves hot hardness and wear resistance compared with standard HSS. This material choice maintains cutting edge stability during continuous operation and supports higher cutting parameters, which in turn reduces tool change frequency and downtime. The DIN 376C specification and ISO2 (6H) tolerance ensure the resulting threads meet established metric standards, providing reliable interchangeability and minimising rejects in production.

Efficient chip control and blind‑hole performance

Built in Form C with a right‑hand spiral 40°, the tool promotes axial chip evacuation into the flutes rather than back into the hole, which is particularly advantageous for blind hole applications. The flanks are relieved to aid entry and reduce friction during tapping; this lowers torque peaks and diminishes the risk of tap breakage. For workshops machining steels of up to 900 N/mm², this geometry balances cutting action and chip removal to achieve a consistent surface finish and thread profile while reducing operator adjustments.

Workshop compatibility and practical handling

The tap features a shank Ø 12 mm, compatible with common machine holders and quick‑change systems, enabling fast tool set‑up and secure clamping during automated or manual use. The specification aligns with DIN 13 sheet 1 for metric threads, simplifying quality control and documentation. By selecting a tool optimised for blind threads and using HSS‑Co, workshops benefit from predictable tool life, fewer rejects and a lower cost per thread in medium‑series production runs.

FAQ

Which materials can be machined with this tap? This tap is designed for machining steels up to approx. 900 N/mm²; the HSS‑Co composition provides the necessary hot hardness for these applications.

Is the tool suitable for blind holes? Yes, the spiral geometry and relieved flanks of the TECWERK machine thread tap make it particularly suitable for blind hole thread production.

What does the tolerance ISO2 (6H) mean for production? The ISO2 (6H) tolerance specifies a standard metric internal thread tolerance that ensures interchangeability and reliable fit with mating external threads produced to the same tolerance class.

How does the 40° spiral affect performance? The right‑hand spiral 40° promotes axial chip evacuation away from the hole bottom, reducing chip congestion and the risk of tap breakage in blind holes.

What machine holders are compatible with the tap? With a shank Ø 12 mm, the tap fits standard holders and quick‑change systems used in milling machines, tapping heads and CNC tapping units.
