TECWERK Machine Tap M4×0.7 (DIN 371B, HSS‑Co, TiCN, 6H)

TECWERK Machine Tap M4×0.7 — a straight‑fluted, Form B machine tap engineered for producing metric ISO through‑threads in corrosion‑ and heat‑resistant steels up to 1000 N/mm²

• HSS‑Co material with TiCN coating
• Straight‑fluted Form B for reliable chip evacuation
• ISO metric thread M4×0.7, tolerance 6H
• Suitable for stainless and heat‑resistant steels

Consistent thread quality for assembly‑ready parts

The TECWERK machine tap delivers reproducible thread form by combining a specified ISO metric thread M4×0.7 with the tighter ISO2 (6H) tolerance band. The flanks are precision ground, which stabilises the cutting geometry and minimises dimensional variation between batches. As a result, components enter assembly with fewer rejected parts and less post‑processing, supporting predictable cycle times and improved first‑pass yield.

Efficient machining in demanding alloys

Manufactured from HSS‑Co and finished with a TiCN coating, the tool excels when cutting corrosion‑, acid‑ and heat‑resistant steels up to 1000 N/mm². The straight flute geometry promotes controlled chip formation for through‑hole tapping, while the specialised peel chamfer reduces insertion torque for clean starts. Together, these features shorten machining cycles and lower the risk of tap breakage under elevated cutting forces.

Reduced downtime through robust design and handling

Durability is supported by a hardened core and wear‑resistant surface treatment, which extend tool life under continuous production use. The tap’s shank Ø 4.5 mm and clear identification via a blue ring simplify changeover and tool identification in toolholders. Maintenance is straightforward: predictable wear patterns make it easier to schedule replacements and keep spindle uptime high, thereby reducing overall production interruptions.

Seamless integration into industrial workflows

Conforming to DIN 371B and supplied as a Form B / Type VA geometry, the tap fits standard machining setups and inspection routines. The combination of standardisation and robust design supports automated manufacturing lines and mixed‑lot production. If application requirements need verification, Metav’s technical advisors can provide guidance on machine speeds, lubrication and clamping to ensure the tap performs optimally in each specific environment.

FAQ

What materials can this tap machine through reliably?
The TECWERK machine tap is suitable for corrosion‑, acid‑ and heat‑resistant steels and is specified for materials up to 1000 N/mm², making it appropriate for many stainless and high‑strength alloys.

What does the TiCN coating provide?
The TiCN coating on this tap improves wear resistance and reduces friction, extending tool life and helping to maintain consistent thread quality across longer production runs.

Which tolerance class does the thread conform to?
Threads produced with this tool meet the ISO2 (6H) tolerance class for metric threads, ensuring compatibility with standard mating components and reliable assembly fits.

Is this tap suitable for through‑hole applications?
Yes — the tap features a peel chamfer specifically designed for through‑threading, facilitating chip escape and lowering insertion torque for cleaner starts.

What identification and handling features aid production use?
The tap is supplied with a blue ring for quick visual identification and a 4.5 mm shank suited to common toolholders, which supports fast changeovers and orderly tool management.
