Machine tap DIN 5156B Univ. G 1/2" x 14 HSS‑Co — Universal straight‑flute pipe tap by TECWERK

The Machine tap DIN 5156B Univ. G 1/2" x 14 HSS‑Co is a universal, straight‑flute pipe tap designed for cutting Whitworth G threads to DIN ISO 228 in through‑hole applications across a wide range of metals

• HSS‑Co construction for long‑life performance
• Universal Form B, straight flute design
• Vapourised coating with green ring identification
• Ground flanks for improved thread quality
• Suitable for Whitworth G threads to DIN ISO 228

Consistent cutting performance under industrial loads

The combination of HSS‑Co substrate and Form B universal geometry ensures a balance of toughness and wear resistance that favours industrial throughput. Straight flutes provide predictable chip control when producing pipe threads, while ground flanks reduce friction at the cutting edge and improve the dimensional accuracy of each thread. These properties translate into fewer reworks and a steadier production rhythm in demanding workshop environments.

Clean through‑threads and reduced rework

A dedicated through‑thread chamfer supports fast entry and continuous chip evacuation for through holes, minimising the risk of chip packing that can cause thread damage. The vapourised coating lowers adhesion and improves sliding properties, which helps to preserve edge geometry during repeated cycles. Conformity to Whitworth G threads and DIN ISO 228 guarantees compatibility with standard pipe fittings and eases integration into existing production processes.

Broad material compatibility for versatile use

The tool is specified for ferrous and non‑ferrous applications, including steel, stainless steel, spheroidal graphite cast iron and non‑ferrous metals, enabling a single tap to cover multiple job types. A 16 mm shank offers robust clamping in standard holders, providing mechanical stability during threading and reducing vibration‑related wear. This versatility reduces tooling inventory and simplifies order management for maintenance and production teams.

Designed for reliable workshop integration

Robust manufacturing and clear identification (green ring) support quick selection and replacement on crowded tool racks. The combination of robust construction and predictable chip behaviour improves overall tool life, reducing unplanned downtime and contributing to a more economical machining process. Where higher cutting speeds or particularly abrasive alloys are in use, pairing this tap with appropriate lubrication and machine settings extends service intervals and supports consistent throughput.
