Machine tap DIN 371C VA M5×0.8 HSS‑Co, nitrided & vapourised (6H) – TECWERK

Machine tap DIN 371C VA M5×0.8 HSS‑Co is a precision metric machine tap designed for forming ISO‑metric threads in blind holes, optimised for stainless and heat‑resistant steels.

• HSS‑Co, nitrided and vapourised finish
• For blind holes, DIN 371C Form C
• ISO2 tolerance (6H) for precision threads
• 6 mm shank, 40° right‑hand helix

Consistent thread quality in high‑strength materials

The combination of a HSS‑Co substrate and nitrided and vapourised surface treatment improves wear resistance and reduces friction during tapping. This results in more consistent thread profiles when working with stainless and heat‑resistant steels that have tensile strengths above 850 N/mm². The benefit for production is straightforward: fewer rejects and longer tool intervals, supporting efficient batch processing and predictable tool costs.

Precision fit through ISO2 tolerance and Form C geometry

Equipped to produce threads to ISO2 (6H) tolerance and manufactured to DIN 13 standards, this tool delivers predictable clearance and engagement for mating fasteners. The designated Form C geometry is optimised for blind holes, ensuring a reliable thread run‑out and minimised risk of tap breakage at the thread root. For applications where assembly accuracy matters, the reduced variation in thread dimensions leads directly to improved component interchangeability.

Improved chip control and machining reliability

A 40° right‑hand helix combined with ground flank relief contributes to controlled chip formation and evacuation when cutting blind holes. Reduced chip packing and smoother clearance lessen the thermal and mechanical load on the cutting edges, extending the service life of the tap and maintaining surface quality. For workshop planning, this translates into fewer interruptions and more stable cycle times on automated tapping operations.

Compatibility with standard toolholding and straightforward handling

The tool is supplied with a 6 mm shank, suitable for common collet and chuck toolholders in machining centres and tapping heads. The metric M5 × 0.8 thread size is widely used across assemblies, making the tap a versatile option in general machining, stainless steel fabrication and maintenance departments. The blue ring identification aids quick selection at the machine, reducing changeover time and supporting orderly tool management.
