Machine Tap DIN 371B M8×1.25 HSS‑Co (6H) – TECWERK

The Machine Tap DIN 371B M8×1.25 HSS‑Co TECWERK is a form B, straight‑flute tap designed for producing ISO metric internal threads in through holes, primarily for steels up to approximately 900 N/mm².

• HSS‑Co for high wear resistance
• Straight flute, form B design
• Metric ISO thread, tolerance 6H

Reproducible, standardised threads for production

This tool follows DIN 371B and produces ISO metric threads with the ISO2 (6H) tolerance field, ensuring interchangeability and repeatable fit in serial production. The standardised geometry reduces scrap rates and simplifies quality control because the thread profile and tolerance class are specified and verifiable. Using a tap with a defined tolerance class supports controlled assembly processes and predictable component behaviour in mechanical systems.

Material performance and why HSS‑Co matters

Manufactured from HSS‑Co, the tap offers increased red hardness and wear resistance compared with standard high‑speed steel, which benefits machining at elevated temperatures and under sustained use. It is specified for use in steels up to approx. 900 N/mm² tensile strength, meaning it is suitable for many construction and engineering steels encountered in workshops and production lines. The material choice extends tool life and maintains thread quality over longer production runs, lowering tool change frequency and downtime.

Geometry that improves chip control and thread quality

The Form B shape with straight flutes supports reliable chip evacuation on through holes, while the flanks honed finish reduces the risk of brittle notch formation and improves thread flank contact. The tap features a specialised chamfer for through‑threading that eases entry and reduces the chance of chip packing at the start of the thread. These design choices translate directly into fewer broken taps, cleaner threads and less rework, especially in automated tapping operations where consistent chip flow is essential.

Practical application, handling and supply reliability

As a machine tap, this tool is intended for powered tapping in a production or maintenance environment; the shaft Ø 8 mm allows secure clamping in common holders. The tap is delivered as a single item in its packaging unit, suitable for immediate integration into machining processes. For complex specifications, batch orders or advice on holder compatibility and process parameters, Metav Werkzeuge provides technical consultation and reliable supply from its European distribution centre, supporting uninterrupted workshop operations and straightforward sourcing for procurement departments.
