TECWERK machine tap DIN 371B VA M3×0.5 HSS‑Co TiCN 6H

The TECWERK machine tap DIN 371B VA M3×0.5 HSS‑Co TiCN 6H is a straight‑flute, TiCN‑coated machine tap designed for producing through metric threads in stainless, acid‑resistant and heat‑resistant steels.

• HSS‑Co construction for improved durability
• TiCN coating reduces wear and extends life
• For through threads in stainless and heat‑resistant steels
• Shank Ø 3.5 mm for secure clamping

Reliable thread quality for assembly and inspection

The combination of DIN 371B geometry and ISO2 (6H) tolerance delivers a consistent thread profile for demanding assemblies. The tap's metric M3×0.5 pitch and the standardised form guarantee interchangeability with DIN‑conforming fasteners, reducing rework and quality checks. Where traceability and repeatable results matter, this machine tap secures a measurable production outcome and supports downstream inspection routines.

Longer tool life and predictable process performance

Manufactured from HSS‑Co and finished with a TiCN coating, the tool resists abrasive wear and thermal degradation during repetitive tapping. The TiCN coating lowers friction and promotes smoother chip evacuation with the straight‑flute geometry, while the pecking or peeling cut is optimised for through threads to avoid material build‑up. The net effect is fewer tool changes and steadier cycle times, improving overall process economy.

Practical handling and material compatibility

Feature details such as relieved flanks, a blue ring identification and a shank Ø 3.5 mm support secure clamping and quick visual sorting at the machine. The tap is specified for use in stainless, acid‑resistant and heat‑resistant steels up to 1000 N/mm² tensile strength, making it suitable for structural components, valves and fittings where corrosion resistance and strength are required. Clear labelling and standard shank diameter simplify integration into existing tool holders.

FAQ

What thread form and tolerance does this tap produce?
The TECWERK machine tap produces a metric M3×0.5 thread to DIN 371B with an ISO2 (6H) tolerance suitable for standardised fastener fits.

Which materials is the tap suitable for?
This tap is specified for stainless, acid‑resistant and heat‑resistant steels up to 1000 N/mm² tensile strength and is therefore appropriate for demanding corrosion‑resistant applications.

How does the TiCN coating benefit performance?
The TiCN coating on the tap reduces friction and wear, improving tool life and enabling more consistent cutting performance when machining tough alloys.

Is the tap suitable for through threads only?
The tap features a peeling cut optimised for through threads, providing clean chip flow; it is configured primarily for through‑hole tapping applications.

What shank size is required for clamping?
The tap has a shank Ø 3.5 mm, which must be matched to the tool holder or collet for secure clamping.
