Machine tap DIN 371C M3 x 0.5 mm – HSS‑Co, TiCN-coated (TECWERK)

The machine tap DIN 371C M3 x 0.5 mm is a workshop-grade, right‑hand spiral tap designed for efficient production of metric ISO threads in blind-hole applications.

• HSS‑Co base metal with TiCN coating
• For blind holes, DIN 371C thread form C
• ISO metric threads to tolerance ISO2 (6H)
• Suitable for stainless and heat‑resistant steels

Reliable tapping for blind‑hole production

The DIN 371C specification ensures a consistent thread geometry that reduces rework and rejects in serial production. The combination of DIN 371C form C geometry with a M3 x 0.5 mm pitch delivers the standardised profile expected in precision assemblies, while the right‑hand spiral assists chip evacuation when working in blind bores. Specifying taps to ISO2 (6H) tolerance provides a close fit suitable for threaded assemblies where clearance and preload are critical, supporting repeatable process results and predictable assembly behaviour.

Reduced tool changes through improved wear resistance

Constructed from HSS‑Co, the tool core maintains cutting performance under higher thermal loads compared with standard HSS, and the TiCN coating lowers friction and increases abrasion resistance. This material and coating pairing is especially advantageous when machining stainless steels and other tough alloys; the tool is rated for steels up to around 1000 N/mm² tensile strength. The net effect is fewer tool changes, longer uninterrupted production runs and lower total process cost per thread—an immediate rational benefit for batch production.

Machine‑ready geometry for consistent cycle times

The tap is supplied in a machine configuration with a compact shaft Ø 3.5 mm, allowing straightforward clamping in standard collets and holders. The right‑hand spiral 40° flute geometry and flanks with relief reduce tapping torque and promote reliable chip control in blind-hole conditions. Conformance to DIN 13 sheet 1 metric standards ensures interchangeable thread quality across different production sites and mating parts. The result is a component‑centric solution that supports stable cycle times and simplifies setup in automated or semi‑automated machining cells.

FAQ

Which materials are suitable for this tap?
This machine tap is intended for stainless and heat‑resistant steels and is specified for materials with tensile strengths up to around 1000 N/mm²; the HSS‑Co substrate combined with the TiCN coating supports these applications.

Is this tap designed for blind holes or through holes?
The geometry and right‑hand spiral 40° flute are optimised for blind holes, aiding chip evacuation away from the bore bottom and reducing the risk of clogging.

What thread accuracy can be expected?
Threads produced to ISO2 (6H) tolerance follow DIN 13 sheet 1 for metric profiles, delivering precise and repeatable fits for M3 x 0.5 mm assemblies.

How is the tool supplied for machine use?
The tap is supplied with a shaft Ø 3.5 mm suitable for standard collets; the compact machine format suits automated tapping cycles and repeatable clamping.
