Take advantage of the combination of HSS‑Co material, durable TiN coating and ISO2 tolerance class to secure consistent, production‑ready threads; order via Metav Werkzeuge or consult our technical team for application advice.

Machine tap DIN 371B M8×1.25 – HSS‑Co, TiN coated (TECWERK)

The Machine tap DIN 371B M8×1.25 is a universal Form B tap designed for machining metric ISO threads in through holes on steels, stainless steels and non‑ferrous metals.

• HSS‑Co construction with TiN coating
• Form B universal straight flute geometry
• ISO2 tolerance class 6H for accurate threads
• Shank Ø 8 mm for standard machine holders

Consistent thread quality for production parts

The geometry and tolerance of this tool are geared towards repeatable results in series production. The Form B design with straight flutes and relieved flanks produces clean chips and reliable thread profiles, while the ISO2 (6H) tolerance ensures threads meet common assembly specifications. For assemblies that demand interchangeability and low rework rates, this combination reduces scrap and downstream fitting time.

Faster cycle times through improved cutting performance

Constructed from HSS‑Co, the tap sustains cutting forces and thermal loads better than standard high‑speed steels, supporting higher cutting speeds where appropriate. The TiN coating lowers friction, improves wear resistance and extends tool life, which together can reduce tool change frequency and increase effective machining time on busy shift schedules. These properties translate into measurable productivity gains on medium‑to‑high mix production runs.

Versatile material compatibility reduces tool inventory

The tool is specified for a broad range of materials — steel, stainless steel and non‑ferrous metals — making it a flexible choice for workshops that run diverse jobs. Its chamfer is suited for through-hole threads, easing thread start and reducing the tendency to form oversized entries. Selecting a universal tap of this specification helps consolidate tooling stock without compromising on process capability.

Integration with standard machining setups and safety margins

With a shank Ø 8 mm, the tap fits common machine holders and tapping heads, enabling straightforward integration into existing tooling systems. The green ring marking aids quick visual identification on the tool board. When used within recommended machine parameters and appropriate coolant practice, the tool supports stable cycle times and predictable maintenance intervals, contributing to a dependable production flow.

Practical explanation of key terms and benefits

The TiN layer is a thin, hard coating that reduces adhesion and surface wear, extending life especially when machining softer alloys or abrasive stainless steels. HSS‑Co denotes high‑speed steel with cobalt alloying, which improves hot hardness and fracture resistance. Form B taps are a universal geometry suited to a range of hole types; straight flutes facilitate chip evacuation in through‑hole tapping. Understanding these terms supports informed tool selection and process optimisation.

FAQ

What materials can be machined with this tap?
The TECWERK machine tap is specified for steel, stainless steel, spheroidal graphite cast iron and non‑ferrous metals, making it suitable for mixed‑material production.

What does ISO2 (6H) tolerance mean for thread fit?
ISO2 (6H) indicates a medium tolerance class that yields consistent, industry‑standard thread fit for metric assemblies when using the DIN 371B universal tap.

How does the TiN coating benefit production use?
The TiN coating reduces surface friction and wear on the tool, extending service life and helping maintain thread quality over longer production runs.

Is the shank size compatible with common tapping holders?
Yes — the shank Ø 8 mm matches many standard machine holders and tapping heads, facilitating quick integration into existing setups.
