Machine Tap DIN 5156B VA G 1/2" x 14 HSS‑Co vapourised ISO 228 by TECWERK

A robust Machine Tap DIN 5156B VA G 1/2" x 14 designed to produce Whitworth (BSPP) pipe threads in through-hole applications and for hard-to-machine alloys

• HSS‑Co with vapourised finish
• Whitworth pipe thread G per DIN ISO 228
• Suitable for stainless and heat-resistant steels

Reliable performance on hard-to-machine materials

The cobalt-alloy HSS‑Co construction delivers sustained cutting hardness at elevated temperatures, making the tap well suited for stainless steels and other difficult alloys. The vapourised finish improves surface hardness and reduces built-up edge, which in turn lowers friction and extends tool life. For production runs where consistency matters, this combination of material and surface treatment supports steady cycle times and predictable regrind intervals.

Precise pipe-thread form and stable chip control

Designed for the BSPP G thread form in accordance with DIN ISO 228, the tool creates accurate sealing threads for fluid and gas systems. The straight flutes assist evacuation in through-threading operations while the flank relief (flank ground) maintains clear cutting geometry on the thread profile. These features reduce the risk of thread deformation and ensure repeatable fits in assemblies that demand tight tolerances.

Machine compatibility and clamping advantages

With a 16 mm shank the tap integrates into standard collet or chuck systems used on machining centres and tapping heads. The tool’s Form B specification suits machine tapping where axial alignment and controlled feed are required. Because the tap is intended for through holes, thread forming and extraction are simplified; the design helps avoid thread breakage and supports straightforward chip flow during plunge-and-retreat cycles.

Practical benefits for workshop workflows

Using this tap for pipelines and connection threads in resistant materials reduces secondary rework and increases first-pass yield. The vapourised surface and cobalt alloy composition mean fewer tool changes for many stainless‑steel tasks, which contributes to predictable scheduling and lower downtime. When combined with Metav’s supply chain reliability, the result is less administrative effort and a steady stock supply for recurring production needs.

FAQ

What thread standard does this tap produce?
The tap produces Whitworth pipe threads (BSPP) in accordance with DIN ISO 228; the specification for the Machine Tap DIN 5156B VA G 1/2" x 14 ensures compatibility with standard G‑thread fittings.

Is the tap suitable for stainless steel and other high-tensile materials?
Yes. The TECWERK machine tap with HSS‑Co and vapourised surface is intended for hard-to-machine materials, including stainless and heat-resistant steels with tensile strength above 850 N/mm².

Can the tap be used for blind holes?
This tool is designed for through threads; for blind-hole tapping a different chamfer or tap geometry is recommended to manage chip evacuation.

What shank size is required for clamping?
The tap has a 16 mm shank, compatible with standard collets and chucks commonly used on machining centres and tapping heads.

How does the vapourised finish benefit production?
The vapourised finish increases surface hardness and reduces friction and built-up edge, leading to longer tool life and more consistent cycle times when threading resistant materials.

Is this tap suitable for automatic machine tapping?
Yes. The Form B geometry and straight flutes make the tool appropriate for machine tapping applications where controlled feed and axial alignment are provided.
