TECWERK machine tap DIN 5156B G 1/2" × 14 HSS‑Co

The TECWERK machine tap DIN 5156B G 1/2" × 14 HSS‑Co is a machine tap designed for cutting parallel Whitworth pipe threads in through‑hole applications, suitable for steels and malleable cast iron under industry conditions.

• HSS‑Co construction for increased tool life
• Straight fluted Form B for reliable chip removal
• Whitworth pipe thread G to DIN ISO 228 standard
• For steels up to 1000 N/mm² and malleable cast iron

Precision and durability for continuous production

The HSS‑Co composition delivers improved red hardness and abrasion resistance compared with standard high‑speed steels, resulting in longer service life under higher temperatures. Combined with a solid 16 mm shank, the tool provides stable clamping and reduced vibration in powered tapping machines, which supports consistent thread geometry and dimensional repeatability. These material and design choices translate directly into fewer tool changes and predictable tool life for production runs.

Consistent thread form and improved surface quality

The Form B geometry with straight flutes is optimised for through threads, promoting effective chip escape and uniform cutting action across each thread flute. The flanks are honed (flanks honed) to remove micro‑burrs and to moderate the cutting edge, improving surface finish and thread fit. By conforming to DIN ISO 228 for Whitworth pipe thread G, compatibility with standard parallel pipe fittings is ensured, reducing the risk of assembly issues and rework.

Efficient chip evacuation and machining reliability

Straight‑fluted taps are particularly advantageous where chips must be ejected through the workpiece rather than consolidated in the flute. This chip evacuation behaviour reduces the likelihood of tap breakage in deeper through holes and keeps cycle times stable. The tool’s geometry and heat‑resistant alloy facilitate reliable performance even during longer sequences, which helps maintain throughput while protecting machine spindles and tapping holders from undue load.

Broad applicability and concise specification

Intended for cutting parallel pipe threads G 1/2" with 14 tpi (threads per inch), the tap is specified for use in carbon and alloy steels up to approximately 1000 N/mm² tensile strength and in malleable cast iron, making it suitable for many maintenance, repair and production environments. The adherence to standard dimensions and thread form supports interchangeability across assemblies.

FAQ

What does Form B mean for tapping performance?
Form B indicates a straight‑fluted geometry suitable for through‑hole taps; the TECWERK tap with Form B promotes reliable chip evacuation and steady cutting action in longer through threads.

Which materials can this tap machine effectively?
The TECWERK HSS‑Co tap is specified for steels up to approximately 1000 N/mm² tensile strength and for malleable cast iron, making it suitable for a wide range of mechanical and hydraulic components.

Is the G 1/2" thread compatible with standard pipe fittings?
Yes; the G 1/2" thread to DIN ISO 228 is a parallel Whitworth pipe thread standard, ensuring compatibility with fittings designed to that specification when used with appropriate sealing methods.

What advantages does the HSS‑Co alloy provide?
HSS‑Co offers higher red hardness and wear resistance compared with conventional HSS, which improves tool life and dimensional stability of threads under elevated temperatures and continuous operation.

Can this tap be used for blind holes?
This specific tap is optimised for through threads; for blind holes a dedicated tap geometry designed to control chip formation in enclosed cavities is recommended.
