Machine tap DIN 371B, M4 x 0.7, HSS‑Co, 6H – TECWERK (Form B, Type H)

The Machine tap DIN 371B M4 x 0.7 HSS‑Co 6H TECWERK is a straight‑fluted metric tap engineered for efficient through‑thread production in high‑strength steels

• HSS‑Co for demanding materials
• Straight flute for reliable chip evacuation
• Optimised for steels >1000 N/mm²
• ISO2 tolerance class 6H for precise fit

Consistent thread quality for high‑stress assemblies

The combination of DIN 371B geometry and M4 x 0.7 metric profile ensures reproducible thread form suited to assembly work where fit and repeatability matter. The 6H tolerance (ISO2) provides a standardised internal tolerance class that supports reliable mating with bolts and fasteners, reducing rejects and rework. This technical certainty benefits production flow by lowering the need for post‑machining inspection and minimising downtime.

Cutting geometry optimised for through‑holes

A straight flute design paired with a specialised peel cut enables controlled chip formation and fast evacuation when producing through threads, which helps prevent clogging in deep or blind operations. The flute and flank relief geometry reduce cutting forces, allowing steady feed rates and more consistent surface finish on the thread flanks. The result is improved cycle times on automated tapping cycles and fewer interrupted threads.

Cobalt‑alloy HSS for enhanced durability

Manufactured from HSS‑Co, the tap exhibits increased heat resistance and hardness retention compared with standard HSS, making it suitable for machining high‑tensile steels with strengths exceeding 1000 N/mm². That material choice translates into longer service life under tough machining conditions and more taps per shift, supporting cost efficiency and predictable maintenance intervals for the toolroom.

Seamless workshop integration and handling

Engineered as Form B, Type H with a shank Ø 4.5 mm, the tool fits common machine tap holders and collets used in production environments. Conformity with DIN 13 Blatt 1 and metric ISO thread standards simplifies quality assurance and inventory management.

FAQ

What materials are suitable for this tap?
The TECWERK machine tap (SKU 2000867214NW) is intended for machining high‑tensile steels and is specified for steels with tensile strength above 1000 N/mm².

Does the tap meet standard thread tolerances?
Yes; the tool produces metric ISO threads to ISO2 (6H) tolerance, compatible with DIN 13 Blatt 1 specifications for internal threads.

How does the peel cut affect performance?
The peel cut is designed for through threads, promoting controlled chip flow and cleaner thread starts, which assists in maintaining cycle reliability on production machinery.

What toolholder compatibility is required?
The tap features a shank Ø 4.5 mm and is suitable for standard machine tap holders and collets used in industrial tapping units.

Is the material heat‑resistant for elevated cutting speeds?
Constructed from HSS‑Co, the tap offers improved heat resistance and hardness retention compared with conventional HSS grades, supporting performance in demanding cutting conditions.
