The solid 25 mm shank and right-hand cutting make the tap suitable for both through and blind holes; order the tool via Metav Werkzeuge or consult the technical team for selection support.

TECWERK HSS hand tap DIN 5157 No.2 — G 1" x 11 tpi, 25 mm shank

The TECWERK HSS hand tap DIN 5157 No.2 is a manual pipe-threading tap for Whitworth G pipes (ISO 228), engineered for workshop threading in steel and general maintenance applications

• High-speed steel (HSS) design
• Whitworth pipe thread G 1" x 11 tpi
• Suitable for through and blind holes
• For steels up to ~900 N/mm² tensile strength

Consistent pipe threads through proven materials and standards

Manufactured from high-speed steel (HSS), this hand tap is built for consistent performance when cutting Whitworth pipe threads. Conforming to ISO 228 and DIN 5157 No.2, the geometry ensures that each pass produces repeatable results suitable for assembly and maintenance tasks. The right-hand cutting configuration is compatible with standard tap holders and manual tap wrenches, while the robust flute form supports reliable chip evacuation. The tool’s specification for steels up to ≈900 N/mm² gives a clear indication of mechanical limits, allowing production planners and workshop technicians to select the correct tool for mild and medium-strength steel workpieces.

Practical benefits for workshop workflows and repair tasks

The combination of an established G 1" x 11 tpi thread form and a 25 mm shank offers practical advantages: stable clamping in holders, reduced vibration, and consistent thread profiles that lower rework rates. Designed for both through and blind holes, the tap handles common pipe-threading situations without the need for multiple specialised tools. The HSS cutting material provides a balance of hardness and toughness, meaning longer tool life under typical workshop conditions and predictable maintenance intervals. Clear standards compliance (ISO 228, DIN 5157) simplifies quality assurance and documentation in regulated environments.

Where this tap adds value and reduces downtime

In maintenance, plumbing retrofit and light production environments, this hand tap enables precise threading with minimal setup. The solid shank diameter aids secure holding in manual or light machine tap holders, promoting alignment and reducing the risk of damaged threads. For operations that prioritise uptime, the durability of HSS and the standardised G thread form support quick replacements and straightforward spare-part management. Overall, the tool helps streamline workflows by delivering reliable threads, cutting down on assembly failures and improving overall process efficiency.

FAQ

Which materials can be machined with this tap?
The TECWERK HSS hand tap is designed for machining steels and is specified for use in materials up to approximately 900 N/mm² tensile strength; it is suitable for typical workshop steelwork.

Is the tap suitable for blind-hole threading?
Yes, the tool is intended for both through and blind holes and features flute geometry that supports chip evacuation in blind-hole conditions.

What thread standard does the tap produce?
The tap cuts a Whitworth pipe thread in accordance with ISO 228 — specifically G 1" x 11 tpi — and complies with DIN 5157 No.2.

How should the tap be clamped for best results?
A secure clamping arrangement matching the 25 mm shank is recommended; stable holding in a manual tap wrench or tap holder reduces runout and ensures consistent thread quality.
