M4x0.7mm HSS-Co Machine Tap Form C TiN Coating ISO Metric 6H For Blind Holes 40° Helix - TECWERK

Take advantage of a high-performance HSS‑Co cutting geometry combined with a TiN wear layer for longer tool life and consistent M4 x 0.7 thread quality; the universal Form C design and 40° right‑hand helix ensure reliable blind‑hole threading in steels and non‑ferrous materials. Order the tap directly from Metav Werkzeuge or consult their specialists for compatibility checks.

TECWERK Machine Tap M4 x 0.7 DIN 371C — HSS‑Co, TiN‑coated

The TECWERK machine tap M4 x 0.7 is a universal Form C tap for metric ISO threads, designed for blind‑hole applications in a range of metals

• HSS‑Co construction for extended tool life
• TiN coating for reduced friction and wear
• Designed for blind‑hole threading
• ISO2 (6H) tolerance for consistent fit

High‑performance cutting for repeatable threads

The TECWERK machine tap combines cobalt‑alloyed HSS (HSS‑Co) with a titanium nitride (TiN) coating to provide a balance of toughness and surface hardness that supports high‑quality thread profiles. The result is consistent thread form and reduced breakage risk when machining metric threads M4 x 0.7. For production environments where thread reliability is essential, this combination delivers measurable gains in uptime and process stability by slowing flank wear and preserving the cutting edge over longer runs.

Broad material compatibility and precise tolerance

Configured to the DIN 371C standard and produced to ISO2 (6H) tolerance, this tool supports machining in steel, stainless steels, spheroidal cast iron and non‑ferrous metals, enabling a single tap to serve multiple material families. The universal Form C geometry and 40° right‑hand helix promote controlled chip formation, especially important for blind‑hole applications, where chip evacuation must be managed to prevent back‑tapping and damage to finished threads.

Reduced tooling inventory and improved economy

By offering a universal cutting form and a corrosion‑resistant surface finish, the tap helps reduce the number of specialised tools required in a workshop. The TiN layer lowers friction and thermal loading, which translates to slower wear and fewer tool changes; the result is lower tooling expenditure over time and less production disruption. The 4.5 mm shank diameter suits standard holders, simplifying integration into existing tool sets and automated tapping heads.

Engineering details that support everyday use

Precision flank honing and a carefully ground flank geometry assist in smooth thread entry and predictable torque behaviour during tapping operations. The Form C universal shape ensures compatibility with common tapping sequences, while the compact design is optimised for blind‑hole depth control. Combined with Metav's distribution and quality assurance, this tap is suitable for both small jobbing shops and larger production lines seeking repeatable M4 x 0.7 thread results.

FAQ

What materials can be tapped with this machine tap?
The TECWERK machine tap is specified for steel, stainless steels, spheroidal cast iron and non‑ferrous metals, making it suitable for varied workshop applications.

Is this tap suitable for blind‑hole threading?
Yes, the tool is designed for blind‑hole applications; the 40° right‑hand helix and flank honing support controlled chip flow in closed‑end holes.

What tolerance does the tap produce?
Threads produced conform to ISO2 (6H) tolerance, corresponding to the DIN 13 standard for metric threads.

What advantages does the TiN coating provide?
The TiN coating reduces friction, increases surface hardness and extends tool life, which helps maintain consistent thread quality over longer runs.

What is the shank diameter and how is the tap held?
The tap has a 4.5 mm shank diameter, compatible with standard holders and many tapping heads used in production and workshop settings.
