TECWERK machine tap M4 x 0.7 mm, DIN 371B, HSS‑Co, 6H

The TECWERK machine tap M4 x 0.7 mm is a Form B, Type AL machine tap designed for through threads in long‑chipping, soft materials and for high‑productivity machining.

• High‑speed cobalt steel (HSS‑Co) construction
• Straight flutes for consistent chip evacuation
• Flank‑relieved geometry for smoother cutting
• Designed for through threads in soft, long‑chip materials

Consistent cutting performance and extended tool life

The tool is manufactured from HSS‑Co (cobalt‑alloyed high‑speed steel) to maintain hardness at elevated temperatures and resist wear during series production. The combination of Form B geometry and flank relief reduces cutting forces and chatter, which leads to more consistent thread profiles and prolongs service intervals. The straight‑flute design promotes controlled chip formation and evacuation, particularly beneficial when machining materials that produce long chips, so cycle times remain stable without frequent interruptions.

Optimised for through‑threading in soft, long‑chip materials

Engineered with a dedicated shearing cut for through threads, this tap reliably forms threads where chip evacuation is critical. The tool is particularly suited to soft, long‑chipping workpieces, delivering a predictable chip flow and minimising the risk of chip jamming. As a result, process stability is improved in repetitive operations and the setup requires fewer manual interventions, supporting efficient production runs and reduced scrap rates.

Precision threads to ISO standards for interchangeability

The tap produces metric ISO threads in accordance with DIN 13 (sheet 1) and is manufactured to the ISO2 tolerance field (6H) for internal threads, ensuring compatibility with standard fasteners and mating parts. The dimensional control guarantees consistent mating behaviour and repeatable assembly quality. The specified M4 x 0.7 mm geometry yields reliable mechanical engagement where thread accuracy is essential for assembly performance.

Workshop integration and handling

A shank diameter of 4.5 mm ensures straightforward clamping in common machine tool collets or holders used for small‑diameter tapping operations. The Type AL designation denotes the specific point and flute treatment that facilitates the intended through‑thread application, reducing rework and minimising cycle interruptions. For integration into existing processes, the tap’s standard compliance and robust material make it suitable for automated tapping units as well as conventional machine tools, supporting both single‑station and multi‑station setups.

FAQ

Which materials is this tap best suited for?
The TECWERK machine tap M4 x 0.7 mm is optimised for long‑chipping, softer workpiece materials where controlled chip evacuation is required, as stated in the product specification.

Does the 6H tolerance ensure interchangeability with standard fasteners?
Yes, the ISO2 (6H) tolerance field corresponds to a common internal thread class that ensures reliable mating with standard metric external threads produced to corresponding tolerance classes.

Is this tap suitable for through‑hole threading?
The tool includes a shearing cut specifically for through threads, enabling effective chip formation and evacuation during through‑hole tapping operations.

What clamping or holder size is needed for this tap?
The tool has a shank diameter of 4.5 mm, which should be accommodated by collets or holders designed for small‑diameter tapping tools; compatibility depends on the machine’s tool‑holding system.

Which standards govern the thread form produced by this tap?
Threads produced conform to DIN 13 (sheet 1) and the DIN 371B form designation, providing standardised geometry and production expectations.
