TECWERK M18×2.5 Machine Tap (DIN 376B) — HSS‑Co, TiN, ISO2 (6H)

TECWERK M18×2.5 machine tap for precise metric threading in demanding workshop and production environments, optimised for through threads and steels up to 1000 N/mm²

• Cobalt HSS for improved wear resistance
• TiN coating for extended tool life
• Straight flutes with honed flanks
• For through threads; ISO2 (6H) tolerance

Precision threading that stands up to continuous use

The combination of a cobalt high‑speed steel (HSS‑Co) substrate and a hard TiN coating provides a balance of toughness and surface hardness, which translates into longer tool life and consistent results. The tool meets DIN 376B and DIN 13 sheet 1 specifications and is produced to the ISO2 (6H) tolerance class, ensuring repeatable thread form and dimensional reliability on every part. These standards support process stability and reduce scrap rates in medium‑ to high‑volume production.

Reliable chip control and clean through threads

Designed with straight flutes and flanks honed, the tap promotes predictable chip evacuation and smooth thread surfaces. The built‑in cutting chamfer for through threads reduces the load at first engagement and improves lead‑in, which is particularly valuable when producing long batches of through holes. The result is reduced chatter, improved thread geometry and fewer interruptions in the machining cycle, supporting faster cycle times and consistent quality.

Compatibility with common machine tool setups

The tap’s Form B design and 14 mm shank suit standard machine holders and automated tapping units, enabling seamless integration into existing tooling rigs. Its metric M18×2.5 geometry and suitability for steels up to 1000 N/mm² make the tool appropriate for a wide range of components in general mechanical engineering and maintenance workshops. The solid construction supports stable torque transmission and repeatable alignment in machine tapping operations.

Built for durability and predictable quality assurance

The surface treatment and honed flank geometry decrease friction and the risk of built‑up edge, extending service intervals and lowering total tooling cost per thread. Compliance with recognised standards provides a verifiable quality basis for procurement and inspection plans. When traceability and process assurance are required, the consistent manufacture and documented specifications of this tap support quality control and audit processes across production lines.
