Machine tap DIN 371C M3 × 0.5 HSS‑Co TiN (6H) by TECWERK

The Machine tap DIN 371C M3 × 0.5 HSS‑Co TiN (6H) by TECWERK produces ISO metric M3 × 0.5 blind threads for medium-strength steels and workshop environments requiring repeatable thread quality

• Cobalt high-speed steel (HSS‑Co) body
• TiN coating for extended tool life
• Form C geometry, right‑hand 40° spiral
• Tolerance ISO2 (6H) for precise fit

Consistent blind-thread performance for workshop series production

The TECWERK tap is designed for reliable creation of blind holes with a geometry tailored to minimise plug‑up and improve chip evacuation. The combination of Form C fluting and a 40° right‑hand spiral supports controlled chip formation, reducing downtime for clearing swarf. This results in a measurable increase in processing stability when producing small ISO metric threads in batches, which is particularly relevant for component assembly processes that demand repeatable torque behaviour.

Material compatibility and hard-use capability explained

Constructed from HSS‑Co, the tool is suitable for machining steels up to 1000 N/mm² tensile strength, offering improved hot‑hardness compared with conventional high‑speed steels. The TiN coating reduces friction and wear, extending tool life under elevated cutting temperatures. For maintenance planning, this means fewer tool changes and lower cumulative tool cost per thread — a direct efficiency gain for production lines that balance cutting performance with predictable life cycles.

Precision fit and tolerance control for secure assemblies

The defined ISO2 (6H) tolerance class ensures thread accuracy compatible with standard ISO metric fasteners, giving assemblies consistent preload and reduced variability in joint strength. The relieved flanks provide a clean thread profile that eases installation while maintaining mechanical integrity. For quality assurance, the DIN 371C designation and referenced standards provide a verifiable basis for procurement decisions and process documentation.

Practical integration into existing tooling systems

With a shank Ø 3.5 mm, the tap is ready for collet or chuck mounting in conventional tapping spindles and CNC tapping heads, enabling straightforward integration into workshop tooling fixtures. The tool’s geometry and coating support stable operation in interrupted and continuous cuts, reducing the need for special cycle changes. For planners seeking predictable throughput, the tap offers an efficient balance of wear resistance and thread accuracy for small‑diameter metric threads.

FAQ

What materials can this tap machine effectively cut?
The TECWERK Machine tap DIN 371C M3 × 0.5 HSS‑Co TiN (6H) is specified for use in steels up to 1000 N/mm² tensile strength and is optimised for common ferrous workshop materials.

Is the tap suitable for blind holes or through holes?
The tool geometry and spiral angle are configured for blind hole threading, providing improved chip control in confined depths.

What does the TiN coating provide in practice?
The TiN coating on the TECWERK tap lowers friction and enhances wear resistance, which contributes to longer tool life and more consistent thread quality under elevated temperatures.

How precise are the threads produced with this tap?
Threads conform to ISO2 (6H) tolerance, delivering repeatable, standardised fit for metric fasteners and reliable joint performance.

What mounting options are compatible with the tap’s shank?
With a shank Ø 3.5 mm, the tap can be held in collets, chucks or dedicated tapping holders compatible with small‑diameter tooling.
