Machine tap DIN 376B, M12 x 1.75 HSS‑Co – Universal Form B (TECWERK)

The Machine tap DIN 376B Universal M12 x 1.75 HSS‑Co vap.6H TECWERK is a universal machine tap designed for producing precise Metric ISO threads in a wide range of engineering materials.

• Cobalt HSS for high wear resistance
• Straight flutes and relief‑ground flanks
• Shear chamfer optimised for through threads
• ISO2 (6H) tolerance for consistent fit

Durable cutting material for higher uptime

The HSS‑Co alloy offers a significantly improved wear resistance compared with standard high‑speed steel, delivering longer service life under demanding conditions. For machining operations in steel, stainless steels, spheroidal graphite cast iron and non‑ferrous metals, the cobalt enrichment raises red‑hardness and thermal stability, which reduces frequent tool changes and supports continuous production. This material choice yields measurable savings in running costs through fewer interruptions and steadier cycle times.

Geometry engineered for precise, repeatable threads

The tap’s DIN 376B specification and Metric ISO thread profile combined with ISO2 (6H) tolerance ensure a predictable clamp and mating fit. Straight flutes promote controlled chip formation and evacuation in through‑thread applications, while the flanks relief‑ground finish reduces cutting forces and the risk of galling. These geometric features lead to consistent thread form and reduced rework, particularly important where assembly tolerances are critical. The tap is supplied with a 9 mm shank compatible with standard machine holders for secure mounting.

Process security and universal application

As a universal (Form B) tap with a vapour‑treated surface and a distinctive green ring identification, this tool is prepared for a broad spectrum of tasks without the need for constant tool swaps. The incorporated shear chamfer is optimised for through threads to produce clean entries and predictable chip flow, enhancing operator confidence and reducing scrap rates. Integration into mixed‑material production lines is straightforward, making it suitable for both jobbing shops and volume environments that demand both flexibility and repeatable quality. For tailored advice on feeds, speeds and machine setup, Metav Werkzeuge’s specialists can provide application‑specific recommendations.

FAQ

What materials can this tap machine for?
The Machine tap DIN 376B M12 x 1.75 HSS‑Co from TECWERK is suitable for steel, stainless steels, spheroidal graphite cast iron and non‑ferrous metals as listed in the product specification.

What does ISO2 (6H) tolerance mean for assembly?
ISO2 (6H) on the TECWERK tap indicates a tighter internal thread tolerance, providing a predictable fit with standard bolts and reducing the need for subsequent adjustment.

How does the vapour‑treated surface affect performance?
The vapour‑treated finish on the TECWERK M12 tap improves surface hardness and reduces friction, which supports longer tool life and more consistent cutting behaviour under load.

Is the tap suitable for through threads only?
The included shear chamfer is optimised for through threads, but the universal Form B design allows the tap to be used in a variety of through‑hole machining scenarios across different materials.

Which machine holders are compatible with this tap?
The 9 mm shank of the TECWERK M12 × 1.75 tap fits standard collets and holders designed for that shank diameter; ensure secure clamping to maintain concentricity and prolong tool life.
