Take advantage of the combination of durable HSS‑Co construction, nitrided and vapour‑treated surface and a rigid 22 mm shank for dependable blind‑hole threading in high‑strength steels; order directly via Metav Werkzeuge or ask the consultants for application advice.

Machine tap DIN 376C VA M30×3.5 mm, HSS‑Co, nitrided & vapour‑treated (TECWERK)

The Machine tap DIN 376C VA M30×3.5 mm is a precision cobalt‑alloy threading tool designed for producing metric ISO threads in high‑strength and corrosion‑resistant steels, optimised for blind‑hole applications in industrial machining.

• HSS‑Co for high‑strength alloys
• Nitrided and vapour‑treated finish
• For blind‑hole threads (ISO metric)
• 22 mm shank for machine rigidity

Consistent ISO threads for demanding materials

Manufactured to the DIN 13 standard and matched to the ISO2 (6H) tolerance field, this tap delivers repeatable metric threads for assemblies where fit and alignment matter. The cobalt‑enriched HSS‑Co composition provides improved hot hardness and edge stability when machining tough, stainless and acid‑resistant steels. The combination of Form C geometry and flank relief reduces cutting forces and helps maintain thread profile accuracy under production loads, enabling predictable assembly behaviour and fewer rejects.

Durable surface treatment for longer tool life

The nitrided and vapour‑treated surface improves wear resistance and reduces built‑up edge formation when working with alloys that promote adhesion. The treatment, visible as the blue ring marking, enhances the tool’s resistance to corrosion and thermal influence during intermittent cutting, which translates into longer service intervals and fewer tool changes. For workshops seeking lower total cost of ownership, this surface finishing notably extends usable life compared with untreated high‑speed taps.

Optimised geometry for blind‑hole threading

With a right‑hand 40° helix and flank relief, the threading tool evacuates chips reliably while preventing premature thread damage in blind holes. The geometry is specifically selected for blind‑hole threading, where controlled chip formation and extraction are critical to avoid tap breakage. The tool’s design ensures that the cutting edges engage progressively, reducing torque peaks and improving process stability even in deep blind‑hole operations.

Machine compatibility and secure clamping

The DIN‑compliant shape and a 22 mm shank provide the rigidity required for machine‑tool application, reducing vibration and increasing thread quality. This tap is supplied in the DIN 376C style suited for machine tapping holders and rigid tooling systems; correct clamping in a suitable holder will ensure concentricity and prolong the life of both tap and workpiece. For tailoring to specific machines or spindle interfaces, Metav Werkzeuge offers expert guidance to match the tap to existing tooling equipment.

FAQ

What materials is this tap suitable for?
The Machine tap DIN 376C VA M30×3.5 mm (TECWERK, SKU 2000867564NW) is intended for stainless, acid‑ and heat‑resistant steels and other high‑strength alloys with tensile strength above 850 N/mm².

Can this tool be used for blind‑hole threads?
Yes, the tap is specifically designed for blind‑hole threading; its geometry and chip control features reduce the risk of tap breakage in blind holes.

What tolerance and thread standard does the tap produce?
Threads produced meet DIN 13 specifications and the tolerance field ISO2 (6H) for metric ISO threads, providing a standardised fit for assemblies.

How does the surface treatment benefit production?
The nitrided and vapour‑treated finish increases wear and corrosion resistance, which extends tool life and maintains consistent cutting performance across runs.

What is the recommended clamping for machine use?
Use a rigid machine tap holder compatible with DIN 376C shank dimensions and ensure secure clamping of the 22 mm shank to minimise runout and vibration.
