TECWERK G 3/4" x 14 HSS-Co Universal Machine Tap (DIN 5156B) – vapour-deposited coating, straight flute

The TECWERK G 3/4" x 14 HSS-Co Universal Machine Tap is a machine-grade pipe-threading tool for producing Whitworth (G) threads to DIN ISO 228 in a wide range of workshop and industrial applications

• High-speed cobalt steel for long life
• Universal Form B for versatile threading
• Vapour-deposited coating with green ring
• Straight flute and relieved flanks for clean chips

Consistent, industrial-grade threads with minimal rework

Manufactured from HSS-Co, this tool is designed for high thermal resistance and extended edge retention on continuous production runs. The tap complies with DIN ISO 228 for Whitworth (G) thread geometry, which supports interchangeability and reliable joint sealing in pipework assemblies. The vapour-deposited coating provides improved surface hardness and wear resistance, so the tool maintains cutting performance over longer cycles and reduces the frequency of regrinding or replacement.

Clean chip control and dependable through-threading

The straight flute geometry combined with relieved flanks and a dedicated peel chamfer for through-threading yields controlled chip formation and safe evacuation during machining. This results in fewer stalled cycles, less thread damage and a reduced need for secondary finishing. For automated or semi-automated machinery where uninterrupted cycle times matter, the design helps maintain process stability and lowers scrap rates.

Suitable for a broad range of workshop materials

Engineered for versatility, the tool cuts effectively in steel, stainless steel, spheroidal cast iron and non-ferrous metals, covering the most common demands in maintenance and production shops. Its universal specification (Form B) enables a balance between performance and robustness, making it appropriate for general-purpose threading tasks without frequent tool changes. Material-specific process parameters should be adjusted to exploit the tool’s cobalt alloy and coating advantages.

Machine integration and secure mounting for stable operation

The solid design includes a 20 mm shank for positive clamping in standard collets and holders used on production machines. The tool’s universal machine-tap profile supports straightforward integration into tool lists and fixtures, enabling rapid changeovers and consistent concentricity. As a result, set-up times are shortened and part-to-part repeatability is improved, supporting efficient throughput on mid- to high-volume runs.

FAQ

What materials can this machine tap cut reliably?
The TECWERK machine tap is suitable for steel, stainless steel, spheroidal cast iron and various non‑ferrous metals, leveraging its HSS‑Co composition and vapour‑deposited coating for sustained performance.

Which thread standard does the tap produce?
The tool produces Whitworth pipe threads conforming to DIN ISO 228 for G 3/4" × 14, ensuring compatibility with standard pipe fittings.

How does the peel chamfer benefit through-threading?
The peel chamfer reduces entry forces and promotes controlled chip removal in through‑holes, improving thread integrity and cutting stability during continuous machining.

Is the shank size compatible with standard machine holders?
Yes, the 20 mm shank is intended for standard collets and holders, offering secure clamping and consistent concentricity on production equipment.

What distinguishes Form B (Universal) for this tap?
Form B provides a general-purpose balance between cutting aggressiveness and robustness, making the tap versatile across common threading tasks without specialised tooling.
