Machine Tap DIN 371C VA M8x1.25 HSS‑Co, nitrided & vapour‑coated — TECWERK

The Machine Tap DIN 371C VA M8x1.25 is a precision machine tap for forming ISO metric M8×1.25 threads in blind holes, designed for high‑strength and corrosion‑resistant steels.

• HSS‑Co for high‑temperature performance
• Nitrided and vapour‑coated surface for wear resistance
• ISO2 (6H) tolerance for precise M8×1.25 threads

Durable alloy and surface treatment for extended tool life

The tap is manufactured from HSS‑Co, a cobalt‑alloyed high‑speed steel that retains hardness at elevated temperatures, which significantly reduces softening during intensive tapping cycles. The additional nitrided and vapour‑coated finish enhances surface hardness and corrosion resistance, so the tool remains sharper for longer when cutting hard, stainless steels and other heat‑resistant alloys. For production environments this translates into fewer tool changes and lower downtime, while maintaining consistent thread quality.

Consistent thread geometry and reliable tolerances

Built to DIN 371C, the tap produces ISO metric threads to ISO2 (6H) tolerance, which ensures repeatable fit and interchangeability with standard fasteners. The right‑hand spiral at 40° combined with relieved flanks promotes controlled chip formation and evacuation in blind‑hole situations. Explained simply: the spiral angle and flank relief help to break chips and guide them away from the cutting edge, reducing the risk of clogging and improving the final thread surface without additional finishing steps.

Machine‑ready design for efficient production

As a machine tap with a shaft Ø 8 mm, the tool is compatible with standard collets and tapping holders, allowing fast tool changes and secure clamping. The geometry and coating are tuned for machining steels with tensile strengths above 850 N/mm², offering efficient material removal and stable cutting forces. The result is shorter cycle times and reduced rework — practical benefits that support higher throughput and lower unit costs in batch production.

FAQ

What materials can this tap machine handle?
The TECWERK machine tap is specified for stainless, acid‑ and heat‑resistant steels and for materials with tensile strengths above 850 N/mm², benefiting from the HSS‑Co composition and surface treatment.

Is the tap suitable for blind holes only?
Yes, the geometry and chip evacuation characteristics are optimised for blind‑hole tapping, as indicated in the tool specification.

What does ISO2 (6H) tolerance mean for thread fit?
ISO2 (6H) denotes a standard tolerance class that ensures a close, repeatable fit with mating ISO metric bolts and nuts; the tap produces threads within this defined dimensional accuracy.

How does the nitrided and vapour‑coated surface help in production?
The combined nitrided and vapour‑coated finish increases surface hardness and reduces friction, which leads to improved wear resistance, cooler cutting conditions and longer tool life in continuous machining.

Can the tap be used in common tapping holders?
Yes, the shaft Ø 8 mm and machine‑tap design make it compatible with standard collets and tapping holders used in production environments.
