Hand tap DIN 5157 No.2 G 3/4" x 14 HSS (ISO 228) – TECWERK

A hand tap DIN 5157 No.2 G 3/4" x 14 HSS engineered for Whitworth pipe-threading to ISO 228, suitable for right‑hand threads in through and blind holes and for steels up to approx. 900 N/mm² tensile strength

• HSS high‑speed steel cutting edges
• Whitworth pipe thread to DIN ISO 228
• Suitable for through and blind holes
• 20 mm shank for secure clamping

Reliable cutting performance for consistent production results

The TECWERK hand tap DIN 5157 No.2 is manufactured from HSS, delivering the hardness and toughness required for routine threading tasks in workshop environments. The tool’s geometry and material choice enable stable cutting behaviour and prolonged edge life when used within its specification for steels up to approx. 900 N/mm² tensile strength. This results in fewer tool changes and reduced process interruptions, supporting a smoother production flow and predictable throughput.

Compatibility with Whitworth pipe systems simplifies assembly work

Designed specifically for Whitworth pipe thread (G) in compliance with DIN ISO 228, the tap produces a 3/4" x 14 tpi thread that matches common pipe fittings and components. Conformity to these standards ensures interchangeability and reduces the risk of misfitting parts in plumbing, hydraulic and machine-installation applications. The right‑hand cutting direction and standard thread form make the tool straightforward to integrate into existing workshop procedures.

Practical design that eases setup and improves clamping security

A 20 mm shank provides a stable interface for chucks and tool holders, improving centring and minimising vibration during manual or light‑machine tapping. The solid shank diameter helps achieve consistent thread coaxiality and reduces the risk of breakage in demanding hand‑tapping operations. For maintenance teams and production technicians, this translates into faster setups and reliable repeatability across batches.

Standards-based construction for dependable workshop use

Complying with DIN 5157 No.2 and ISO 228 means the tool is compatible with established quality expectations and workshop norms. The tap is suitable for both through and blind holes, offering flexibility across repair and manufacturing tasks. Given its specification and robust HSS material, the tool is particularly well suited for routine mechanical workshops, service departments and industrial maintenance where standardised pipe threads are frequently required.

FAQ

What thread does the tap cut?
The TECWERK hand tap cuts a Whitworth pipe thread G 3/4" x 14 tpi in accordance with DIN ISO 228, suitable for standard pipe fittings.

Is the tap suitable for hardened steels?
This tap is designed for use in steels with a tensile strength of up to approx. 900 N/mm² and is not intended for high‑hardness or case‑hardened materials beyond that range.

Can the tap be used in a tapping machine?
The tool is primarily a hand tap but the 20 mm shank and robust HSS construction allow use in light tapping machines or holders that securely accept the shank diameter.

What distinguishes DIN 5157 No.2 specification?
The DIN 5157 No.2 designation describes the tap style and geometry suitable for general-purpose threading tasks, offering a balance between strength and chip evacuation for standard workshop use.
