Threading die Form B M5×0.8 HSS‑E 6g, TECWERK — Closed pre‑slit die for hard materials

A Threading die Form B M5×0.8 HSS‑E 6g designed for cutting metric ISO threads in demanding materials where dimensional accuracy and tool life are essential

• HSS‑E with cobalt for enhanced wear resistance
• Metric ISO thread M5×0.8, tolerance 6g
• Closed, pre‑slit Form B for precise thread profile
• Suitable for stainless and heat‑resistant steels

Reliable cutting performance for high‑strength materials

The die is manufactured from HSS‑E (cobalt‑alloyed high‑speed steel) in accordance with DIN EN 22568, providing superior hot hardness and abrasion resistance compared with conventional high‑speed steels. This material choice is particularly beneficial when machining stainless, heat‑ and acid‑resistant steels and special alloys, where elevated temperatures and abrasive wear are frequent. The tool is specified for use in steels with tensile strength up to 1200 N/mm², which supports operations on tougher grades without premature loss of cutting geometry. Such properties translate into fewer tool changes and more stable production cycles.

Accurate thread form with controlled tolerance and profile

The closed, pre‑slit Form B construction secures the full thread profile during cutting while the pre‑slit feature provides limited springing for chip evacuation and slight diameter variation. This combination helps to achieve the specified tolerance field 6g for an M5×0.8 metric ISO thread, reducing the likelihood of rework or assembly fit issues. Conformity to DIN 13 metric thread standards is maintained, so threads produced with this die integrate reliably into standardised assemblies. The modest 7 mm height ensures compatibility with compact die holders and supports fine axial control during manual or light‑machine applications.

Durability, handling and application advantages

Due to the cobalt‑enriched cutting material and robust design, the die offers a balance of longevity and consistent cutting geometry that benefits batch production and maintenance tasks alike. The closed construction protects the cutting edges and helps maintain thread quality over multiple uses; the pre‑slit arrangement reduces clogging risk when working with sticky or gummy materials. Where process reliability matters, these attributes contribute to predictable uptime and lower scrap rates. For specification clarifications or process recommendations, Metav’s consultants are available to support selection and integration into existing tooling layouts.

FAQ

What materials can be machined with this die?
The Threading die Form B M5×0.8 HSS‑E 6g (TECWERK, SKU 2000867842NW) is intended for stainless, heat‑ and acid‑resistant steels as well as many special alloys and steels with tensile strengths up to 1200 N/mm².

Does the die meet metric standards for interchangeability?
Yes, the die is produced to metric ISO thread specifications and references DIN 13, delivering a 6g tolerance suitable for standardised assembly fits.

What advantage does HSS‑E offer compared with standard HSS?
HSS‑E contains cobalt, which enhances hot hardness and wear resistance; this increases tool life and performance when cutting tougher or heat‑generating materials.

How does the closed, pre‑slit Form B affect thread quality?
The closed design ensures a complete thread profile while the pre‑slit feature allows limited flexing and improved chip clearance, supporting consistent tolerance control and fewer machining interruptions.

Is this die compatible with standard die holders?
The 7 mm height and Form B geometry are compatible with common compact die holders intended for metric threading operations; holder compatibility should be confirmed against specific toolholder dimensions.
