TECWERK machine tap DIN 5156B — G 3/8" × 19, HSS‑Co, vapourised

The TECWERK machine tap DIN 5156B is a universal straight‑flute tapping tool designed for producing Whitworth pipe threads G 3/8" in steel, stainless steels, spheroidal graphite cast iron and non‑ferrous metals

• HSS‑Co for high wear resistance
• Whitworth pipe thread G to DIN ISO 228
• Straight flutes with flank relief
• 12 mm shank for secure clamping

High endurance for continuous production

Built from HSS‑Co, this machine tap delivers increased wear resistance and consistent thread quality under continuous use. The vapourised treatment improves surface hardness and reduces built‑up edge, which translates into longer tool life and fewer interruptions in production. The universal geometry (Form B) offers a balance between robustness and cutting action, enabling predictable cycle times in repetitive machining processes. Such performance reduces downtime and supports stable process planning on milling or tapping heads.

Clean chip control and precise Whitworth pipe threads

The straight flutes combined with flank relief and a dedicated peel cutting edge for through threads ensure reliable chip evacuation and a defined thread profile. Conforming to DIN ISO 228, the tap produces parallel Whitworth pipe threads G 3/8" × 19, suitable where standard pipe fittings and seals are required. The straight‑flute design is particularly advantageous for through holes and helps to avoid chip packing; this yields a cleaner thread form and minimises rework in assembly operations.

Versatile application and secure clamping

Engineered for a wide material spectrum, the tool is suitable for steel, stainless steels, spheroidal graphite cast iron and non‑ferrous metals, making it a practical choice for mixed production runs. The 12 mm shank gives reliable retention in collets and tool holders, improving concentricity and reducing runout. As a universal tap, it is designed to simplify tooling inventories while maintaining the capacity to meet varied component specifications; the single‑piece packaging supports straightforward integration into workshop workflows.
