TECWERK machine tap DIN 5156C – G 3/4" × 14, HSS‑Co

The TECWERK machine tap DIN 5156C G 3/4" × 14 is a universal cobalt high‑speed steel tap designed to produce Whitworth pipe threads (DIN ISO 228) in blind holes and standard bores across a wide range of workshop materials.

• HSS‑Co construction for high wear resistance
• Whitworth pipe thread G 3/4" × 14
• Vapourised surface with green ring marking
• Suitable for steel, stainless and non‑ferrous metals

High‑performance threading for consistent pipe connections

The tapped thread quality is driven by the HSS‑Co substrate and the Form C, universal geometry which together deliver reliable thread form and long tool life. Conformity with DIN 5156C and DIN ISO 228 ensures compatibility with established Whitworth pipe systems, reducing the risk of misfits and sealing issues. This translates into fewer rejects and lower rework rates on assemblies where leak‑tight joints are essential. The combination of geometry and material enables efficient metal removal while maintaining the required pitch and flank form for durable pipe fittings.

Material versatility that reduces tool inventory

Designed for machining a broad range of materials, the tool performs well in steel, stainless steel, spheroidal cast iron and non‑ferrous metals, widening its applicability across general workshop and industrial applications. Using a single universal tap for multiple substrates reduces the need for frequent tool changes, streamlines setup procedures and lowers stocking complexity. The result is improved uptime on production lines and a simpler spare‑parts strategy for maintenance teams and small workshops alike.

Geometry engineered for blind holes and controlled chips

The tap features a 40° right‑hand helix and flank honing to promote chip control and reduce the tendency for jamming in enclosed holes. Intended for blind‑hole thread production, the honed flanks and helix angle assist chip evacuation and prevent premature wear at the cutting edges. The solid shank with 20 mm diameter offers secure clamping in standard holders, contributing to concentricity and repeatable thread accuracy when used on conventional tapping heads or CNC tapping spindles.

Protective finish, clear marking and machine compatibility

A vapourised surface treatment with a green ring marking increases surface hardness and wear resistance while helping to reduce galling in stainless materials. The universal Form C profile and the HSS‑Co material make the tool robust under moderate cutting conditions and compatible with a wide range of machine tool setups. Packaged as a single unit, the tap is ready for immediate integration into workshop tooling systems and supports efficient maintenance routines thanks to predictable service life and straightforward handling.
