High-precision threading and robust cutting performance are combined in this TECWERK machine tap: HSS‑Co construction, 40° helix and ISO 6H tolerance deliver reliable M4 x 0.7 metric threads in blind holes; order via Metav Werkzeuge or consult the technical advisors for application support.

Machine tap DIN 371C Univ. M4 x 0.7 mm HSS‑Co (TECWERK) — 40° helix, vapourised finish

Machine tap DIN 371C Univ. M4 x 0.7 mm HSS‑Co is a universal machine tap engineered for producing accurate metric ISO threads in blind holes and suited to a wide range of engineering materials.

• HSS‑Co high‑speed steel, Form C
• Metric ISO thread M4 x 0.7, DIN 13-1
• Spiral right‑hand flutes, 40° helix
• Suitable for blind holes; ISO tolerance 6H

Consistent thread accuracy for assembly and interchangeability

The M4 x 0.7 thread is produced to DIN 371C with an ISO 6H tolerance, ensuring interchangeability and predictable fit in assembly lines. The cobalt‑alloyed HSS‑Co material gives the tool elevated hot hardness and wear resistance compared with standard high‑speed steels, which translates into fewer rejects and longer in‑service life. This is particularly relevant where repeated, tight‑tolerance threading is required; the specified ISO tolerance class reduces scrap rates and supports reproducible quality across batches.

Geometry and finish that improve productivity

A 40° helix combined with spiral right‑hand flutes promotes efficient chip control when machining blind holes, minimising the risk of chip packing and rework. The vapourised finish contributes to reduced friction and easier chip flow under interrupted cuts, while the relieved flanks reduce contact stresses at the thread crest for smoother cutting action. Together these features help shorten cycle times and reduce machine downtime, making the tap a pragmatic choice for production environments where throughput and consistency matter.

Versatile performance across commonly used materials

Designed as a universal solution (Form C), the threading tool is suitable for steel, stainless steels, spheroidal graphite cast iron and a variety of non‑ferrous metals, offering flexibility when a single tool must cover diverse workpieces. The combination of geometry and material grade allows stable performance across these substrates, reducing the need for specialised inventories. For workshop planners this means fewer tool changes and simpler tooling logistics while maintaining the quality of internal threads in critical components.

Practical fitment and machine integration

The tap features a compact shank with a shank diameter of 4.5 mm, making it compatible with a wide range of machine holders and collets for automated tapping cycles. Its design for blind holes and the metric standardisation (DIN and ISO references) make it straightforward to integrate into CNC setups and machining cells. The universal classification reduces stocking complexity, and the clearly defined technical parameters support quick verification during setup and quality control.

FAQ

What materials can be tapped with this machine tap?
This Machine tap DIN 371C Univ. M4 x 0.7 mm HSS‑Co is designed for use in steel, stainless steels, spheroidal graphite cast iron and various non‑ferrous metals.

Is the tap suitable for blind holes or through holes?
The TECWERK tool is specifically set up for blind holes and incorporates a helix and flute geometry that assists chip evacuation in such applications.

What does ISO 6H tolerance mean for threaded parts?
ISO 6H indicates the tolerance class for internal metric threads; the Machine tap DIN 371C Univ. M4 x 0.7 mm HSS‑Co produces threads within that tolerance for consistent fit and interchangeability.

How does the vapourised finish affect performance?
The vapourised finish reduces friction and improves chip flow, which can enhance tool life and reduce torque during cutting when using the TECWERK tap.

Which standard does this threading tool comply with?
The tap conforms to DIN 371C and references DIN 13‑1 for metric ISO threads, ensuring standardised dimensions and compatibility.
