TECWERK machine tap MF12×1.5 DIN 374B – HSS‑Co, Form B

The TECWERK machine tap MF12×1.5 DIN 374B is a machine tap engineered for producing metric ISO fine threads in steels, malleable cast iron and long‑chip non‑ferrous metals with consistent dimensional accuracy.

• HSS‑Co for enhanced wear resistance
• Form B with straight flutes and relieved flanks
• Tolerance field 6H for precise thread fit

Reliable material performance for demanding threads

The threading tool is manufactured from HSS‑Co (cobalt high‑speed steel), a material selected to provide improved hardness and wear resistance when machining tougher grades. Combined with the tolerance field 6H and compliance with DIN 13, the tool produces metric ISO fine threads with reproducible fits, which is essential where thread accuracy affects assembly performance and interchangeability. This composition and specification support machining in steels up to ca. 1000 N/mm², malleable cast iron and long‑chip non‑ferrous metals, ensuring the tool sustains dimensional stability over longer production runs.

Optimised geometry for clean chip control and reliable starts

The Form B geometry with straight fluted design and relieved flanks improves chip formation and evacuation when cutting fine threads, reducing the risk of jamming in through holes. The integrated shear chamfer for through threads enhances the thread start and minimises burr formation, which shortens secondary finishing operations. These features translate into fewer interruptions, steadier cycle times and a more reliable machining process in automated or manual tapping setups.

Practical design for workshop integration and tool life

With a shank Ø 9 mm, the tool is designed for secure clamping in standard machine holders and collets, allowing straightforward integration into existing production equipment. The combination of a machine‑grade shank and the cobalt alloy matrix ensures improved resistance against softening at elevated cutting temperatures, extending useful service life and reducing replacement frequency. The tool’s specification as a machine tap makes it suitable for production environments where repeatability and throughput matter, while the geometry minimises rework and supports efficient downstream assembly.

FAQ

What materials can be machined with this machine tap?
The TECWERK machine tap MF12×1.5 DIN 374B is suitable for steels up to ca. 1000 N/mm², malleable cast iron and long‑chip non‑ferrous metals as indicated in the product specification.

What does the tolerance field 6H mean for thread fit?
Tolerance field 6H, specified for this machine tap, denotes the standard internal thread tolerance for metric ISO threads and ensures consistent, snug fits in typical assembly applications.

How does the shear chamfer help with through threads?
The integrated shear chamfer on the tool improves the thread start and chip separation when producing through threads, which reduces burrs and the need for secondary finishing.

Is the shank diameter compatible with standard machine holders?
Yes, the shank Ø 9 mm is intended for secure clamping in common collets and holders used in machine tapping operations.

Why is HSS‑Co chosen for this tap?
HSS‑Co (cobalt high‑speed steel) provides higher hot hardness and wear resistance compared with standard HSS, which benefits thread quality and tool life when machining tougher materials listed for this tap.
