Machine tap DIN 371C VA M6×1mm HSS‑Co, nitrided and vapour‑coated by TECWERK — right‑hand 40° spiral for blind‑hole threading

Machine tap DIN 371C VA M6×1mm HSS‑Co, nitrided and vapour‑coated — a precision threading tool designed for machine use, ideal for forming ISO metric threads in high‑strength and corrosion‑resistant steels for blind holes

• HSS‑Co material for high wear resistance
• Nitrided and vapour‑coated cutting edges
• 40° right‑hand spiral for blind‑hole threads
• Metric ISO M6×1 with tolerance ISO2 (6H)

Consistent thread quality in high‑strength steels

The HSS‑Co composition provides elevated red hardness and abrasion resistance, which translates into reliable thread form when machining stainless, acid‑ and heat‑resistant steels with tensile strengths above 850 N/mm². The combination of substrate and surface treatment — nitrided and vapour‑coated — reduces flank wear and maintains cutting geometry over longer production runs, resulting in fewer rejects and less rework. Conformity with DIN 13, sheet 1 and the ISO2 (6H) tolerance class ensures the produced threads meet recognised metric standards for interchangeability.

Longer service life through treated surfaces and relief geometry

Surface engineering delivers measurable benefits for workshop productivity. The nitrided layer and vapour coating improve resistance to abrasive wear and adhesion of built‑up edge, while the relieved flanks reduce friction during thread formation. These design choices collectively extend tool life and support predictable performance under repeated loading. The durable finish, paired with the cobalt‑alloyed high‑speed steel, provides a balance between toughness and hardness that is particularly beneficial for short‑chipping, demanding materials.

Efficient blind‑hole threading with optimised helix and form

A 40° right‑hand spiral is specified to facilitate chip control in blind‑hole threads, directing chips away from the cutting edges and reducing the risk of clogging. The tool’s Form C geometry and flank relief contribute to clean chip evacuation and accurate thread flanks, which is essential for tapped blind holes where chip accumulation can compromise thread integrity. The metric M6×1 profile, produced to DIN 13, delivers standardised fit and function for assembly work in precision engineering and maintenance operations.

Practical workshop integration and handling details

The tap is manufactured in the machine tap DIN 371C variant with a 6 mm shank, allowing straightforward clamping in standard machine tool holders. Identification by the blue ring simplifies tool selection on the production floor. Supplied as a single unit per packaging, the design focuses on pragmatic adoption: robust material choice, surface treatment for longevity and geometry targeted at blind‑hole performance. These elements together support a predictable production flow and lower overall tooling cost per part.

FAQ

Is this tap suitable for machining stainless and heat‑resistant steels?
Yes. The Machine tap DIN 371C VA M6×1mm HSS‑Co is designed for rust‑, acid‑ and heat‑resistant steels with tensile strength above 850 N/mm², thanks to the cobalt alloy and surface treatments.

What thread form and tolerance does the tool produce?
The tool produces a metric ISO thread M6×1 in accordance with DIN 13, sheet 1, with a tolerance class of ISO2 (6H) for standardised fit.

Can the tap be used for blind holes?
Yes. The right‑hand 40° spiral and the tool’s geometry are intended for blind‑hole threads, promoting chip evacuation away from the cutting zone.

What are the main wear‑resistance features of this tap?
Wear resistance is achieved through the HSS‑Co substrate combined with nitrided and vapour‑coated surfaces; the relieved flanks further reduce friction during cutting.
