TECWERK Machine Tap DIN 376C M20×2.5 HSS‑Co TiCN (6H), Form C

The TECWERK Machine Tap DIN 376C M20×2.5 is a high‑performance machine tap for producing metric ISO threads in stainless, acid‑ and heat‑resistant steels, optimised for blind‑hole applications.

*HSS‑Co core for high wear resistance *TiCN coating for longer tool life *Designed for blind‑hole threading *Suitable for stainless and heat‑resistant steel

Consistent metric threads for critical assemblies

This tool delivers precise M20×2.5 metric threads in line with DIN 376C and the ISO2 (6H) tolerance field, which reduces the need for post‑processing and ensures interchangeable parts fit first time. The combination of a high‑grade HSS‑Co substrate and controlled geometry provides dimensional stability during production runs; this lowers scrap rates and supports predictable cycle times in series manufacture. The result is repeatable accuracy where component tolerances are non‑negotiable.

Optimised geometry for reliable blind‑hole tapping

Engineered with a 40° spiral right‑hand flute and specific flank relief, the tap promotes efficient chip formation and evacuation when working in blind holes. This geometry minimises chip packing and the associated risk of thread damage, thereby improving process reliability on interrupted or deep‑bottomed threads. The design therefore supports faster, uninterrupted tapping cycles and reduces the frequency of tool changes in a production setting.

Coating and identification that extend tool life

A hard TiCN coating enhances surface hardness and wear resistance while reducing built‑up edge formation in difficult materials; identification is simplified by the blue ring marking. The coating, together with the cobalt alloy substrate, is suited to machining stainless, acid‑ and heat‑resistant steels up to 1000 N/mm² tensile strength, offering longer service life and fewer tool interventions. Fewer tool changes mean higher machine uptime and lower per‑part tooling cost over series production.

Secure clamping and workshop integration

The tap features an Ø16 mm shaft for robust toolholding and compatibility with standard machine tap holders, supporting concentricity and reducing chatter. Form C construction and the specified flute geometry ensure compatibility with automated tapping cycles and common machining centres. Integration into existing tooling systems is straightforward, enabling quick adoption without specialised adaptors and facilitating a seamless workflow on the shop floor.

FAQ

What materials is this tap suitable for? This TECWERK machine tap is suitable for stainless, acid‑ and heat‑resistant steels and is rated for materials up to 1000 N/mm² tensile strength.

Is the tap suitable for blind holes only? The tool is optimised for blind‑hole threading thanks to the 40° spiral and flank relief, but it can also be used where chip evacuation is manageable in through‑holes.

What does the TiCN coating provide? The TiCN coating increases surface hardness and reduces built‑up edge, extending tool life when machining tough alloys and stainless steels.

Which tolerance does the tap achieve? Threads are produced to the ISO2 (6H) tolerance field in compliance with DIN 13 and DIN 376C specifications for metric internal threads.

What is the shaft diameter for machine holding? The tap has an Ø16 mm shaft, providing secure clamping in standard machine tap holders.
