M8x1.25mm Metric Machine Tap DIN 371B HSS-Co Vapourised ISO2 (6H) With Chamfered Lead, 8mm Shank - TECWERK

Take advantage of the combination of HSS‑Co cutting material, ISO2 (6H) tolerance and straight‑fluted geometry for reliable, repeatable threads in production environments; order the tap directly via Metav Werkzeuge or consult the team for application advice.

TECWERK machine tap DIN 371B universal M8×1.25 HSS‑Co, vapourised, 6H

A universal machine tap M8×1.25 for cutting metric ISO threads to DIN 13, designed for use in steel, stainless steels, nodular cast iron and non‑ferrous metals.

• Cobalt HSS for higher hot hardness
• Form B universal, straight‑fluted design
• ISO metric M8×1.25, tolerance ISO2 (6H)
• Vapourised finish and green identification ring

Consistent threads that reduce rework and downtime

The TECWERK machine tap is engineered to deliver consistent, standardised thread quality in serial production. Manufactured to DIN 371B and DIN 13 specifications with a tolerance ISO2 (6H), the tool ensures interchangeability and dimensional conformity, which reduces rejects and secondary processing. The use of HSS‑Co (cobalt high‑speed steel) raises red hardness and wear resistance, so the tap maintains cutting geometry under thermal load and prolonged cycles.

Geometry optimised for through holes and chip evacuation

The straight‑fluted, Form B geometry provides a predictable cutting action and effective chip control when producing through threads. The tap’s design includes a dedicated peel cut for through threads, which eases chip release and lowers thread distortion during insertion. These features make the tool particularly suitable for mixed‑material workshops working with steel, stainless steels, spheroidal graphite cast iron and non‑ferrous metals, offering a balance between thread quality and operational reliability.

Surface treatment and edge preparation for longer service life

A vapourised finish and green identification ring mark the tool’s treated surface, contributing to improved sliding properties and reduced adhesion of swarf. The flanks are ground back to refine the cutting edge and reduce friction on the mating material, which extends tool life and helps keep thread tolerances stable across batches. The result is a robust tap that preserves edge geometry and offers predictable wear behaviour in demanding production runs.

Machine compatibility and practical workshop advantages

With a shank Ø 8 mm and universal Form B dimensions, the tap fits standard toolholders and machining centres used in small and medium workshops. Conformance to ISO metric thread standards and DIN 13 documentation supports quality assurance processes and simplifies procurement for maintenance and series production. For operations seeking reliable thread production with minimal setup variation, this tap offers a clear technical basis for process standardisation.

FAQ

What materials can this tap machine?
The TECWERK machine tap is specified for use in steel, stainless steels, spheroidal graphite cast iron and non‑ferrous metals, matching the material list contained in the product documentation.

Does the tap meet recognised thread standards?
Yes. The tap produces metric ISO threads in accordance with DIN 13 Blatt 1 and is manufactured to the DIN 371B profile with a tolerance field of ISO2 (6H).

How does the vapourised finish help performance?
The vapourised finish on the TECWERK tap reduces friction and improves swarf release, supporting longer tool life and more consistent thread forms under repetitive use.

Is the shank compatible with standard holders?
The shank diameter is 8 mm and is suitable for common collets and toolholders used in machine tapping operations.
