3mm Thread Forming Tap M3 Form C TiN Co HSS-Co 6HX For Through And Blind Holes - TECWERK

Benefit from a durable TiN coating, cobalt high‑speed steel construction and a straight‑fluted geometry that together enable reliable ISO metric M3 threads in both through and blind holes; order this form tap directly via Metav Werkzeuge or contact our consultants for technical advice.

Thread former DIN 2174 (DIN 371) M3 — Form C, HSS‑Co, TiN — TECWERK

A Thread former DIN 2174 (DIN 371) M3 designed for producing ISO metric M3 threads in ductile metals and steels, suitable for both through and blind hole applications.

• HSS‑Co construction for high wear resistance
• TiN coating for extended tool life
• Straight flutes with relieved flanks
• Tolerance 6HX for ISO metric M3 threads

Longer service intervals through robust materials and coating

The combination of HSS‑Co (cobalt high‑speed steel) and a TiN coating gives a clear advantage in demanding production environments: improved wear resistance and lower thermal sensitivity translate into longer tool life and fewer tool changes. Forming taps rely on displacement rather than cutting; the cobalt alloy base material sustains the stresses of material flow during forming, while the TiN layer reduces friction and adhesion. This makes the tool a rational choice where consistency and uptime matter most, particularly in repetitive assembly or batch production.

Consistent, repeatable ISO M3 threads with controlled fit

Engineered as a form tap with straight flutes and relieved flanks, the tool produces reliable threads without chip evacuation, delivering a clean, work‑hardened thread root that often improves thread strength. The specified tolerance 6HX ensures consistent dimensional results for ISO metric M3 threads and predictable assembly behaviour when paired with standard mating parts. For customers less familiar with tolerance classes: 6HX denotes a reproducible internal thread tolerance aimed at standard fits, helping to avoid surprises during component assembly.

Application guidance and material suitability

This forming tap is intended for ductile materials — listed uses include non‑ferrous metals and steels with at least 10% elongation — where material displacement is possible without fracture. Its geometry supports both through and blind hole forming, offering flexibility across component types. The tool’s thread length of 11 mm and shank diameter of 3.5 mm provide concise engagement and stable clamping in standard toolholders. When selecting a forming tap, ensure the workpiece material meets the ductility requirement; otherwise, a cutting tap should be chosen instead.

FAQ

What materials can be formed with this tool?
The TECWERK form tap is suitable for non‑ferrous metals and steels that exhibit at least 10% elongation; such ductile materials allow the displacement process necessary for forming threads.

Is this tap suitable for blind holes?
Yes — the tool is specified for both through and blind hole applications and is designed to form M3 threads without chip formation in appropriate materials.

What does the tolerance 6HX mean for assembly?
The 6HX tolerance field indicates a reproducible internal thread tolerance for ISO metric M3 threads, supporting predictable fit and assembly performance when used with standard mating parts.

How does a forming tap differ from a cutting tap?
A forming tap displaces material to create the thread profile rather than removing chips; this usually produces stronger thread roots and avoids chip management, but it requires sufficiently ductile workpiece material.

What are the key dimensions to check before ordering?
Check the M3 thread size, the thread length of 11 mm and the shank diameter of 3.5 mm to ensure compatibility with the workpiece requirements and the toolholder.
