Machine tap DIN 376C M22×2.5 HSS‑Co 6H (TECWERK) — Form C, 40° right‑hand helix

The Machine tap DIN 376C M22×2.5 HSS‑Co 6H is a Form C tapping tool designed for producing metric ISO blind‑hole threads in medium‑high strength steels in machine applications.

• HSS‑Co for enhanced wear resistance
• Form C geometry with 40° helix
• ISO2 tolerance (6H) for precision fit
• Designed for blind‑hole threading in high‑strength steel

Consistent ISO‑accurate threads for reliable assembly

The combination of DIN 13 Blatt 1 standards and the ISO2 (6H) tolerance class ensures repeatable thread quality for assembly lines and maintenance work. The specified M22×2.5 profile offers a predictable fit with mating nuts and components, which reduces rework and scrap rates. Using a machine tap conforming to these standards simplifies quality control: thread gauges and go/no‑go checks can be applied directly, shortening inspection times and improving throughput.

Optimised geometry for safe blind‑hole machining

The Form C design together with a 40° helix and relieved flanks promotes controlled chip formation and breakage in blind‑hole applications. This geometry reduces the risk of chip jamming at the thread root and lowers tapping forces, which benefits both tool life and spindle loads. For machine operations where chip evacuation is constrained, this tap’s profile helps maintain consistent cutting conditions and reduces thread defects in enclosed bores.

Cobalt‑alloy high‑speed steel for extended service life

Manufactured from HSS‑Co, the tap delivers improved heat resistance and wear resistance compared with standard high‑speed steels. That metallurgical choice keeps cutting edges stable when tapping steels up to approximately 900 N/mm², offering longer intervals between resharpening or replacement. The material balance supports cost‑effective production: fewer tool changes translate into reduced downtime and steadier cycle times on CNC and industrial tapping machines.

Workshop‑ready shank and simple machine integration

With a shaft Ø 16 mm and machine tap standard dimensions, the tool mounts easily in common tap holders and collet chucks used in industrial workshops. The robust shank reduces the chance of runout, helping to produce concentric, high‑quality threads even under heavy feed or slight alignment deviations. Compatibility with standard holders and the straightforward geometry mean quick setup and predictable performance in repetitive machining tasks.

FAQ

What diameter and pitch does this tap produce?
The tap produces an M22×2.5 metric ISO thread; the specification is stated on the machine tap DIN 376C M22×2.5 HSS‑Co 6H.

Is this tool suitable for blind‑hole tapping?
Yes, the Form C geometry and helix design make the tap particularly suitable for blind‑hole threading, reducing chip packing in the bore.

Which materials can be machined with this tap?
The TECWERK tap is intended for machining steels up to approximately 900 N/mm² and is manufactured from HSS‑Co for improved wear resistance in such applications.

What does the tolerance class ISO2 (6H) mean for mating parts?
ISO2 (6H) indicates a standard internal thread tolerance ensuring a reliable, standard fit with corresponding external threads and fasteners.

How should the tap be mounted for best results?
Use a rigid machine holder or suitable collet chuck with correct alignment; the 16 mm shank diameter provides stable clamping and minimises runout.
