TECWERK machine tap DIN 371B VA M3×0.5 HSS‑Co – nitrided and vapour‑coated for high‑strength steels

TECWERK machine tap DIN 371B VA M3×0.5 HSS‑Co is a straight‑fluted machine tap designed for ISO metric M3×0.5 threads in demanding stainless and heat‑resistant steels

• HSS‑Co for high strength materials
• Nitrided and vapour‑coated surface finish
• Straight flute with flank relief
• ISO M3×0.5, tolerance ISO2 / 6H

Consistent cutting performance for demanding alloys

The tap delivers repeatable results when machining stainless and heat‑resistant steels with tensile strengths above >850 N/mm². The HSS‑Co composition provides higher hot hardness than standard high‑speed steels, which reduces wear when cutting tough alloys. The straight flute geometry and flank relief offer stable chip formation in through‑holes, while the identification blue ring and the compliance with DIN 13 ensure straightforward tool selection and process validation in production environments.

Surface treatment and tool life that reduce downtime

A combined nitrided and vapour‑coated treatment increases surface hardness and lowers friction at the cutting edge, extending service life under intermittent production conditions. This surface engineering reduces galling and adhesive wear when tapping corrosion‑resistant materials and therefore helps maintain thread tolerance over longer production runs. The design focuses on predictable consumption so tool change intervals can be planned, supporting efficient maintenance cycles and fewer unplanned stops.

Standards and tolerance for assembly reliability

Manufactured for ISO metric M3×0.5 threads to DIN 13 with tolerance field 6H (ISO2), the tap secures thread fit and interchangeability for fasteners and components. The integrated chip‑relief geometry and the through‑thread cutting chamfer simplify production of blind and through holes, ensuring reliable clamp and assembly behaviour. For customers specifying mechanical interchangeability, this tool supports conformity checks and traceable quality assurance across batches.

Workshop handling and integration into processes

The tool includes a 3.5 mm shank for secure clamping and is produced in the Form B straight‑flute style to suit automatic tapping spindles and toolholders. The measured, industrial‑grade construction eases integration into CNC and tapping stations without extensive parameter tuning. With documented material suitability and a consistent manufacturing standard, the tap allows machining planners to predict cycle times and maintain throughput with fewer trial cuts.
