Machine tap DIN 376C M20x2.5 HSS‑Co 6H — TECWERK machine tap with 40° right‑hand spiral

A machine tap DIN 376C M20x2.5 HSS‑Co 6H engineered for efficient production of metric ISO threads in blind holes, suitable for machining medium‑high strength steels.

• HSS‑Co wear resistance
• Right‑hand spiral 40° for chip removal
• For blind‑hole threads
• Shank Ø 16 mm for secure clamping

Built for consistent production and reduced downtime

The tap is manufactured from HSS‑Co, a cobalt‑alloyed high‑speed steel designed to maintain cutting performance at elevated temperatures, which translates into longer tool life under continuous machine use. With Form C geometry and compliance with DIN 13, the tool produces a metric ISO thread to 6H tolerance; this combination ensures repeatable, standardised threads that reduce rework and scrap. For production environments where component conformity matters, the proven geometry and material composition deliver predictable results and minimise unplanned stoppages.

Geometry that prevents jamming and improves surface finish

A right‑hand spiral 40° actively channels chips away from the cutting edge when creating blind holes, reducing the risk of chip packing and thread breakage. The tool’s flank relief (flanks undercut) lowers friction between tap and workpiece, aiding evacuation and improving thread flank integrity. Together these features support smoother tapping cycles and a superior surface finish, which benefits downstream assembly and coating processes and increases first‑pass yield on batches.

Durability and suitability for demanding steels

Rated for use in steels up to approximately 900 N/mm², the cobalt‑alloyed microstructure of the tool preserves hardness and edge stability during the heat and stress of cutting. This resilience means fewer tool changes and consistent dimensional control across runs. The material choice and heat‑resistant properties ensure the tap can cope with higher cutting temperatures common in higher strength steels, making it a robust option for maintenance shops and production lines alike.

Compatibility with machine tooling and practical handling

Designed for machine tapping, the item features a 16 mm shank for secure clamping in standard toolholders, supporting stable rotation and precise coaxial alignment. Compatibility with the DIN 376C specification simplifies tool selection for metric thread programmes. For application advice, Metav’s specialists can provide recommended feed and spindle settings based on the workpiece material and machine type to optimise cycle time and tool life, ensuring integration into existing production workflows with minimal setup time.
