Hand tap set DIN 5157 G 1/4" HSS ISO 228 — TECWERK, right‑hand cutting

The Hand tap set DIN 5157 G 1/4" provides HSS taps for Whitworth pipe threads to ISO 228, suitable for through and blind holes and for steels up to approx. 900 N/mm²

• HSS cutting material for durability
• Whitworth pipe thread G to ISO 228
• Right‑hand cutting for conventional machines
• Suitable for steels up to approx. 900 N/mm²

Precise Whitworth threads for reliable pipe joints

This tap set is designed specifically for producing Whitworth pipe threads to ISO 228, which ensures compatibility with standard fittings and avoids mismatched connections. Conformity to the standard means the produced threads meet expected dimensions and tolerances, reducing assembly time and the need for rework. For operations requiring dependable sealing and mechanical integrity, the set delivers repeatable results that integrate into existing production and maintenance procedures.

Durable high‑speed steel for consistent performance

Manufactured in HSS (high‑speed steel), the cutters combine toughness with heat resistance to withstand typical workshop stresses. The material choice helps maintain cutting geometry across multiple operations, extending tool life when working with medium‑strength steels — specified here up to approx. 900 N/mm². Because the taps are right‑hand cutting, they are compatible with standard tapping procedures and common tapping handles, enabling rapid changeover and predictable machining behaviour in everyday industrial use.

Two‑step system for efficiency and reduced breakage

The set comprises a starter tap (Vor‑schneider) and a finishing tap (Fertigschneider), a sequence that eases chip evacuation and reduces torque during thread generation. Using a tapered or starter cutter first produces a guiding thread, then the finishing cutter brings the thread to full dimensions and surface quality, improving thread accuracy and lowering the risk of tap breakage. This two‑step approach is particularly beneficial in blind‑hole applications and where consistent thread form is a production priority.

Workshop compatibility and handling benefits

With a shank diameter of 11 mm, the taps fit common tap handles and adapters used in professional shops, simplifying storage and tool selection. The set is suitable for both through and blind holes, offering flexibility across maintenance, plumbing and fabrication tasks. Clear labelling and ISO conformity make inventory control and procurement straightforward for purchasing departments that prioritise standardisation and traceability.
