M20x2.5mm Die Form B HSS-Co For Hard-to-Machine Alloys, Form B 18mm - TECWERK

Take advantage of a durable HSS‑Co cutting grade and a precise 6g tolerance to produce repeatable M20×2.5 metric threads in demanding materials; order the TECWERK threading die via Metav Werkzeuge or consult the Metav team for application matching.

Threading die Form B, M20×2.5 HSS‑Co 6g — TECWERK (Metrical ISO thread)

Threading die Form B, M20×2.5 HSS‑Co 6g designed for cutting ISO‑metric threads in hard‑to‑machine steels and special alloys, with a closed, pre‑slotted configuration for reliable chip control

• HSS‑Co grade for high wear resistance
• Metric ISO M20×2.5 DIN 13 threading
• Tolerance field 6g for precise fit
• Suitable for steels up to 1200 N/mm²

Consistent, industrial‑grade thread quality for production use

The HSS‑Co cutting material (cobalt‑alloy high‑speed steel) provides elevated hot‑hardness and abrasion resistance compared with standard HSS, so the tool sustains its cutting geometry under thermal load. Specified as DIN EN 22568 and intended for metric ISO threads, the die produces a repeatable M20×2.5 profile in accordance with DIN 13, which supports interchangeability on assemblies. The closed design ensures a full‑profile thread, while the pre‑slotted geometry aids chip breaking to maintain surface finish and reduce rework.

Reduced downtime and extended service life for demanding materials

Designed for processing stainless, heat‑ and acid‑resistant steels and a range of special alloys, the die is rated to handle workpiece strengths up to 1200 N/mm², enabling use on tougher substrates without premature wear. The 6g tolerance delivers a reliably snug fit where thread engagement and assembly integrity matter; this reduces the need for corrective machining and streamlines production flow. For workshops focused on throughput, the combination of durable material and precise tolerancing lowers total rework time.

Practical application and handling recommendations for workshop integration

With a nominal height of 18 mm and Form B configuration, the component fits standard die holders and handles conventional cutting fluids for improved chip evacuation and surface finish. The designation Type VA indicates the manufacturer variant and compatibility within the same product family. For best results on high‑strength or stainless steels, use appropriate lubricant and stable fixturing; the robust construction supports repeated use in a production setting while preserving thread geometry and dimensional accuracy.

FAQ

What materials can this die machine effectively?
The TECWERK threading die is suited for stainless, heat‑ and acid‑resistant steels and various special alloys, and is specified for applications up to 1200 N/mm² tensile strength.

What does the 6g tolerance mean for assembly?
Tolerance 6g indicates the external thread fit class in the metric ISO system, providing a consistent fit that supports reliable assembly without excessive clearance.

Is the die compatible with standard die holders?
Yes; the Form B geometry and 18 mm height align with common die holder dimensions used in machining and maintenance shops.

Why choose HSS‑Co over standard HSS for threading?
The HSS‑Co grade offers improved hot‑hardness and wear resistance, extending tool life and maintaining cutting edges during intermittent heat exposure typical of stainless and high‑strength steels.

What is the function of the pre‑slotted, closed form?
The closed, pre‑slotted form ensures full‑profile threads while the slots help break chips and reduce clogging, improving surface finish and reducing the risk of tool seizure.
