Machine tap DIN 5156B VA, G 5/8" × 14 tpi – HSS‑Co, vapourised finish (TECWERK)

The Machine tap DIN 5156B VA, G 5/8" × 14 tpi is a specialised tool for producing Whitworth pipe threads in through holes according to ISO 228, designed for demanding materials and industrial production.

• HSS‑Co construction for high wear resistance
• Nitride and vapourised surface for longer life
• Straight flutes with relieved flanks for chip control
• Whitworth G 5/8" × 14 tpi for sealed pipe threads

Durable cutting performance for demanding alloys

The tap is manufactured from HSS‑Co, providing a tougher microstructure that resists abrasive wear and thermal softening in interrupted or heavy cutting. The nitride and vapourised surface treatments reduce friction and improve resistance to built‑up edge, which translates into fewer tap replacements and longer uninterrupted production runs. For workshops and small series production, this combination reduces downtime and contributes to a predictable tool life in quantities where repeatability matters.

Reliable Whitworth pipe threads with reduced rework

Conforming to DIN ISO 228, the tool generates consistent Whitworth G thread form for sealed pipe connections, minimising subsequent fitting or reworking. The specification 14 tpi is implemented with tight dimensional control to ensure compatibility with standard fittings. Because the geometry is optimised for through threads, chips are guided away from the cutting zone, lowering the risk of thread damage and improving first‑pass yield in pipework and hydraulic component manufacture.

Geometry and surface finish that improve process stability

The straight flutes and relieved flanks are designed to provide controlled chip evacuation and reduced radial cutting forces, resulting in cleaner thread flanks and better surface integrity. The shank Ø 18 mm promotes rigid clamping in standard toolholders, reducing run‑out and extending the useful life of both the tap and the machine spindle. In practice, this means fewer rejects and a smoother integration into CNC production or manual tapping machines.

Suited to stainless and heat‑resistant steels with predictable results

This tool is specified for use on stainless steels, acid‑ and heat‑resistant alloys and other difficult‑to‑cut materials with tensile strengths above >850 N/mm² tensile strength, where ordinary high‑speed taps wear prematurely. The selected material and coatings minimise adhesive wear and maintain cutting geometry under higher temperatures. For operations that require consistent sealing threads in corrosive or high‑temperature environments, the construction and finishes of this tap offer a balance of precision and longevity.

FAQ

What thread standard does this tap produce?
The tap produces Whitworth G threads according to DIN ISO 228, supplying standardised, sealed pipe threads suitable for fittings and hydraulic connectors.

Is the tool appropriate for stainless and heat‑resistant steels?
Yes, the TECWERK tap in HSS‑Co with nitride and vapourised surface is specified for difficult‑to‑cut materials including stainless and heat‑resistant steels with tensile strengths above >850 N/mm², where enhanced wear resistance is required.

What is the shank size and how does it affect clamping?
The tool features a shank Ø 18 mm, which supports secure clamping in standard holders and reduces run‑out for improved thread precision.

Is this tap suitable for through holes only?
The geometry is optimised for through threads, promoting chip evacuation; it is specified for through‑hole applications to reduce the risk of chip congestion.
