Take advantage of the combination of high wear resistance from the TiCN coating and the toughness of HSS‑Co for consistent ISO threads; order the component directly via Metav Werkzeuge or contact the consultants for application advice.

TECWERK machine tap DIN 371C GG M3 x 0.5 mm — TiCN-coated HSS‑Co, tolerance 6HX

TECWERK machine tap DIN 371C GG M3 x 0.5 mm is a precision threading tool for industrial machining, designed for reliable production of ISO metric threads in cast‑iron materials.

• HSS‑Co substrate with TiCN coating
• Straight fluted with flanks ground for accuracy
• Tolerance field 6HX for ISO metric M3 x 0.5
• Suitable for grey and graphite cast irons

Reliable thread quality for cast‑iron components

The tap combines a HSS‑Co substrate with a TiCN surface finish to deliver a balance of toughness and wear resistance that suits abrasive cast materials. The 6HX tolerance field ensures that threads comply with ISO metric standards, reducing rejects and rework in series production. The combination of material choice and coating is particularly effective when machining grey cast iron and graphite cast iron, where edge stability and reduced built‑up edge extend tool life and maintain consistent thread form.

Consistent cutting behaviour and dimensional stability

A straight fluted geometry with ground flanks provides stable chip control and precise thread profiles, especially when producing both through and blind holes. The DIN 371C Form C design and Type GG classification contribute to predictable performance in automated tapping operations, while the modest shank Ø 3.5 mm supports secure clamping and alignment in dedicated tapping spindles. These features translate into measurable gains in process reliability and less downtime for tool changes.

Practical advantages for workshop and production use

The TiCN coating reduces friction and increases surface hardness, which means longer intervals between tool replacements and improved cost efficiency in the long run. The tool is specified for both through‑hole and blind‑hole tapping, enabling flexible use across repair work and repetitive production tasks. Clear identification via the white ring simplifies inventory handling and ensures the correct tool is selected at the machine, supporting a smoother workflow on the shop floor.

Selection and application guidance

For optimal results, select cutting parameters that match the base material and hole type; the HSS‑Co core tolerates higher thermal loads than standard HSS, while the TiCN layer favours moderate cutting speeds with reliable surface protection. When used in materials such as grey cast iron, the tool gives a balance of life and dimensional accuracy; in graphite cast iron and tempered cast types, its robustness reduces the risk of premature failure. Consider slight pecking cycles for deeper blind holes to aid chip evacuation and maintain thread integrity.
