Machine tap DIN 371C VA M8×1.25 HSS‑Co TiCN 6H – TECWERK, TiCN-coated cobalt high-speed steel, 40° right‑hand helix

The Machine tap DIN 371C VA M8×1.25 is engineered to cut ISO metric M8×1.25 threads in blind holes, especially in stainless and heat‑resistant steels up to 1000 N/mm².

• TiCN coating for extended tool life
• Cobalt HSS (HSS‑Co) for high toughness
• 40° right‑hand helix for reliable chip evacuation
• For blind holes and ISO metric threads 6H

Consistent ISO threads for demanding metals

The DIN 371C machine tap delivers precise ISO metric threads to the ISO2 (6H) tolerance, making it suitable where repeatability and fit are critical. With a metric profile compliant with DIN 13 sheet 1 and a nominal size of M8×1.25, the tool produces threads that match standard fasteners, reducing rework and ensuring reliable assemblies. The design is particularly appropriate for technicians and production engineers who require consistent thread quality in corrosion‑resistant and heat‑treated alloys.

Durable construction for longer tool life and fewer tool changes

Constructed from HSS‑Co and finished with a TiCN‑coating, the tap resists wear and thermal stress during high‑load operations. The coating reduces friction and improves surface hardness, which in turn extends service intervals and lowers tooling costs over time. The blue ring marking provides quick visual identification, while the relief‑ground flanks help maintain cutting edges under intermittent loads. These attributes combine to support uninterrupted workflows in small‑batch production and maintenance shops alike.

Geometry optimised for blind‑hole threading and chip control

A 40° right‑hand helix paired with flank relief‑ground geometry is engineered to evacuate chips effectively in blind holes, minimising the risk of jamming and thread damage. The spiral characteristic directs swarf away from the cutting zone and reduces axial thrust during entry, which is especially beneficial when working with stainless or heat‑resistant steels up to 1000 N/mm² tensile strength. The tool’s shaft diameter of 8 mm suits a wide range of machine holders, enabling straightforward integration into existing machining setups.

Ready for industrial use and straightforward integration

As a Type VA, Form C machine tap, the tool is marked for ease of identification and conforms to recognised standards for interchangeability. The combination of TiCN‑coating, HSS‑Co substrate and the specified helix angle ensures compatibility with common workshop and production processes. The overall package supports machine shops, service departments and production lines that prioritise precision, reproducibility and minimal process disruption; handling and mounting follow standard practice for machine taps of this class.
