M5x0.8mm Machine Tap DIN 371C Form C HSS-Co Vapourised 6H For Blind Holes, 6mm Shank - TECWERK

Take advantage of the combination of HSS‑Co durability, a 40° spiral geometry for reliable chip evacuation and an ISO2 (6H) thread tolerance for repeatable assembly results; order the tap directly via Metav Werkzeuge or contact our consultants for tailored advice.

TECWERK Machine tap DIN 371C Universal, M5 × 0.8, HSS‑Co, ISO2 (6H)

The TECWERK Machine tap DIN 371C Universal M5 × 0.8 is a machine tap designed for producing blind‑hole metric ISO threads in steels, stainless steels and non‑ferrous metals.

• HSS‑Co for high wear resistance
• Universal form C with 40° right‑hand spiral
• ISO metric thread to DIN 13, tolerance 6H
• Suitable for blind holes and diverse materials

Consistent thread quality for repeatable assemblies

The DIN 371C geometry combined with the ISO2 (6H) tolerance ensures consistent thread form and reliable interchangeability across production batches. Adherence to DIN 13 Sheet 1 gives a clear reference for fit and function, which supports quality control processes and simplifies inspection routines. The universal form reduces the need for multiple tap variants, helping to standardise thread production and improve process throughput.

Robust material and coating for extended tool life

Manufactured from HSS‑Co (cobalt high‑speed steel) and treated with a vapourised coating, the tool resists built‑up edge and tolerates elevated cutting temperatures better than unalloyed high‑speed steel. The combination reduces wear rate and extends service intervals on the shop floor. Flank reliefs and the specific geometry lower cutting forces, which can reduce vibration and the risk of tap breakage during machine tapping operations.

Designed for blind holes and efficient chip control

The 40° right‑hand spiral is optimised for blind‑hole tapping, actively directing chips back into the hole core and out of the cut zone. This geometry decreases the likelihood of chip packing and minimises rework. The relieved flanks further assist chip formation and evacuation, delivering cleaner threads and reducing post‑process finishing. Where access is constrained, this tap achieves dependable results without complex process changes.

Versatile application across common workshop materials

This machine tap is suited to a broad range of substrates: steel, stainless steel, spheroidal graphite cast iron and non‑ferrous metals. The universal classification and robust material choice make it appropriate for both short runs and repetitive manufacturing tasks. A 6 mm shank diameter permits secure seating in standard machine holders, supporting stable rotation and axial feed for machine tapping cycles.

FAQ

What materials can be tapped with this machine tap?
The TECWERK machine tap is suitable for steel, stainless steels, spheroidal graphite cast iron and various non‑ferrous metals, as indicated in the specification.

Is this tap intended for blind holes or through holes?
This DIN 371C universal tap is optimised for blind holes; the 40° spiral promotes effective chip evacuation in such applications.

What does the ISO2 (6H) tolerance mean for assembly?
ISO2 (6H) denotes a standardised internal thread tolerance that ensures interchangeable fit and consistent assembly quality for metric threads.

How does the vapourised coating affect performance?
The vapourised coating improves wear resistance and heat tolerance, extending tool life under typical machine tapping conditions compared with uncoated taps.

What is the shank diameter and how should it be held in the machine?
The tap has a 6 mm shank diameter, suitable for secure clamping in common machine holders and tap holders used for machine tapping operations.
