Machine tap DIN 5156C Univ.G 1 in x 11 – TECWERK (HSS‑Co, vapour‑coated)

Machine tap DIN 5156C Univ.G 1 in x 11 – TECWERK is a universal machine tap designed for producing Whitworth G pipe threads in blind holes, compliant with DIN ISO 228

• HSS‑Co high‑performance cutting material
• Vapour‑coated for improved wear resistance
• Right‑hand spiral 40° for reliable chip control
• Suitable for steel and non‑ferrous materials
• 25 mm shank for stable machine mounting

Precise thread form and consistent production results

The combination of HSS‑Co and the universal Form C geometry delivers a stable cutting edge and predictable tool life in series production. The tap is manufactured to meet DIN ISO 228 for Whitworth G thread tolerances, which ensures interchangeability and reduces rework in assemblies. For machining blind holes the design provides reliable chip formation and evacuation, lowering the risk of thread defects and subsequent repair work. These attributes translate into consistent throughput and fewer production interruptions.

Optimised chip flow and reduced breakage risk

A right‑hand spiral 40° and flank relief ground geometry promote controlled chip flow away from the cutting zone, particularly important when working with sticky materials. The vapour‑coated surface improves lubricity and wear resistance, helping heat and friction management during high‑volume tapping. As a result, the tool sustains performance in mixed‑material workshops and decreases the incidence of tool breakage, which supports higher overall equipment effectiveness.

Workshop compatibility and efficient tool handling

With a 25 mm shank and universal type shank form, the tap integrates easily with standard tapping heads and machine tool holders, reducing changeover time. The tool is suitable for a broad range of materials including steel, stainless steel, spheroidal cast iron and non‑ferrous metals, making it a versatile choice for fabrication, maintenance and MRO tasks. The robust construction of the tap supports repeatable thread quality across batches, helping to streamline procurement and tool inventory for production planners.
