G 3/8" x 19 HSS Hand Tap DIN 5157 Right-Hand Thread Through & Blind Holes, 12mm Shank - TECWERK

Take advantage of the robust combination of precision thread form, durable HSS cutting material and a secure 12 mm shank to ensure consistent pipe connections in production and maintenance tasks; order the item directly via Metav Werkzeuge or consult their specialists for application guidance.

Hand tap G 3/8" x 19 tpi – HSS, DIN ISO 228 (TECWERK)

The hand tap G 3/8" x 19 tpi is a tool for cutting Whitworth pipe threads to DIN ISO 228 standard, suitable for general workshop and industrial pipe‑fitting applications.

• HSS construction for durable cutting
• Whitworth pipe thread G 3/8″ × 19 tpi
• Right‑hand cutting for through and blind holes
• 12 mm shank diameter for secure clamping

Consistent pipe-thread form for reliable connections

The tap produces the Whitworth pipe thread defined by DIN ISO 228, delivering a standardised thread profile appropriate for many fluid and gas fittings. Manufactured from HSS, the tool maintains cutting geometry under the loads typical for pipe‑threading, which helps reduce rework and leak risks. The right‑hand cutting geometry supports both through and blind holes, providing predictable chip formation and thread quality in materials with tensile strengths up to 900 N/mm².

Secure clamping and practical workshop handling

A 12 mm shank enables stable clamping in hand tap wrenches or suitable collets, improving concentricity during manual tapping operations. The combination of a standardised shank and a conventional tap length makes the tool compatible with common workshop fixtures, reducing setup time. This physical compatibility, together with the tool’s straightforward geometry, supports a smoother workflow and lowers the probability of cross‑threading or tap breakage.

Material compatibility and cutting performance

Designed for machining steels up to approximately 900 N/mm², the tool’s HSS composition balances hardness and toughness for repeated use in mixed‑material environments. The specification indicates suitability for non‑hardened steels and typical workshop alloys; the robust cutting material helps the tap retain a sharp cutting edge longer than standard carbon steel alternatives, which benefits throughput and tool life. The thread pitch of G 3/8" × 19 tpi provides fine engagement suitable for many pipe assemblies where sealing integrity is essential.

Integration into production and maintenance routines

Incorporating a standardised, HSS hand tap from TECWERK into routine maintenance or production kits supports operational consistency across multiple workstations. The tap’s compatibility with both through and blind hole applications reduces the need for specialised variants and simplifies inventory. For procurement and supply chain reliability, the tool is supplied in single units and can be ordered to replenish workshop stocks or to standardise tooling across departments.

FAQ

What thread form does the tap produce?
The tap cuts a Whitworth pipe thread to DIN ISO 228, specified as G 3/8" × 19 tpi for the TECWERK hand tap (SKU 2000867106NW).

Which materials can be machined with this tap?
The tool is suitable for steels up to approximately 900 N/mm² tensile strength and comparable workshop alloys when using the recommended cutting conditions.

Can the tap be used in blind holes?
Yes, the right‑hand cutting geometry of the TECWERK hand tap is designed for both through and blind holes, offering controlled chip evacuation.

What clamping or driving interface is required?
A secure clamping method compatible with a 12 mm shank—such as a tap wrench or collet—is recommended to ensure concentricity and reduce breakage risk.

Is the tap appropriate for production or occasional maintenance?
The HSS construction and standard thread form make this tap suitable for both regular maintenance and light production tasks where standardised pipe threads are required.
