M5x0.8mm Machine Tap DIN 371C HSS-Co Form C Right-Hand 40° Undercut Flanks ISO2 (6H) - TECWERK

Combining HSS‑Co tool steel with a Form C (DIN 371C) geometry and a 40° right‑hand spiral, this machine tap delivers reliable M5 × 0.8 metric threads for blind‑hole applications and is suitable for steels up to approximately 900 N/mm²; order the TECWERK machine tap directly via Metav Werkzeuge or ask our consultants for technical guidance.

TECWERK machine tap DIN 371C M5 × 0.8 HSS‑Co (Form C, 6H)

The TECWERK machine tap M5 × 0.8 is a machine tap designed to produce metric ISO threads in blind holes, combining a Form C profile with a right‑hand spiral for secure chip evacuation in steel applications

• HSS‑Co for enhanced wear resistance
• Form C profile, DIN 371C standard
• Right‑hand spiral 40° for blind holes
• Suitable for steels up to ~900 N/mm²

Precise thread form for consistent assemblies

The Form C profile, specified to DIN 371C, creates a controlled ISO metric thread with tolerance ISO2 (6H), which translates into reliable fit and repeatability in serial production. The geometry minimises dimensional variation and supports secure fastener engagement, reducing rework and downtime. When tight assembly tolerances matter, this tap offers predictable performance and contributes to consistent product quality across batches.

Material selection and cutting performance for tougher steels

Made from HSS‑Co (cobalt‑alloy high‑speed steel), the tool provides improved heat resistance and wear life compared with conventional high‑speed steels. The right‑hand spiral 40° and flank relief promote chip control in blind‑hole tapping, lowering the risk of chip jamming and thread breakage. With a shank diameter of 6 mm, the tool suits standard machine holders and supports stable cutting action when paired with correct speeds, feeds and cutting fluid.

Practical integration into workshop and production lines

This machine tap is intended for machine tapping operations where efficiency and tool life are priorities. The combination of spiral‑point design and HSS‑Co material reduces tool changes and improves uptime, while adherence to established standards simplifies process qualification. For procurement and stocking, the tap is a compact addition to a workshop’s tapping range, offering compatibility with common M5 fastener requirements and straightforward replacement in automated cells.

FAQ

What materials is this tap suitable for?
The TECWERK machine tap M5 × 0.8 is specified for use in steels up to approximately 900 N/mm² and is optimised for ferrous applications where the HSS‑Co composition improves wear resistance.

Can this tap be used for blind holes?
Yes — the right‑hand 40° spiral and relief geometry are designed specifically for blind‑hole tapping, aiding chip evacuation into the flutes and reducing the chance of chip congestion.

Which thread standard and tolerance does it produce?
This tap cuts metric ISO threads M5 × 0.8 to DIN 371C with tolerance field ISO2 (6H), complying with DIN 13 Blatt 1 where repeatable fit and interchangeability are required.

What are the advantages of HSS‑Co in this tool?
The HSS‑Co material offers higher red hardness and improved wear resistance compared with standard HSS, enabling longer tool life and better performance at elevated cutting speeds; the tool features a 6 mm shank for stable clamping.

Is this tap suitable for machine tapping operations?
Yes — the design is intended for machine tapping; the combination of Form C geometry and spiral fluting supports efficient automated use and predictable thread quality (SKU 2000867265NW).
