TECWERK hand tap set G 1/2" — HSS, DIN ISO 228, 2-piece

A compact hand tap set designed for Whitworth pipe threads G 1/2", suitable for both through and blind holes in steels up to approx. 900 N/mm².

• HSS cutting material for long tool life
• Whitworth pipe thread G 1/2" (14 tpi) compatibility
• Two-piece set: roughing and finishing taps
• Shank Ø 16 mm for sturdy clamping

Faster, reliable thread making for workshop routines

The solid high-speed steel (HSS) construction delivers a consistent cutting edge, which translates into longer service life and fewer tool changes in daily use. Compliance with DIN ISO 228 ensures threads meet established pipe-fitting standards, supporting predictable assembly and leakage-free connections. The combination of a roughing and a finishing tap reduces machining time: the first tool removes material rapidly, while the second ensures the final thread tolerance and surface. This sequence increases throughput without sacrificing precision and is particularly effective where repeatability matters.

Practical design that simplifies machining and reduces downtime

Equipped for both through-hole and blind-hole applications, the set’s right-hand cutting geometry and clear designation for G 1/2" (14 tpi) threads make selection straightforward for maintenance and fabrication tasks. The robust shank diameter of 16 mm provides secure clamping in standard tap holders and T-handles, reducing wobble and improving concentricity. The two-piece approach helps avoid premature wear: the roughing tap lowers cutting forces, while the finishing tap restores geometry, resulting in cleaner threads and less rework for trades such as plumbing, hydraulics and workshop fabrication.

Durable workmanship, straightforward standards, and shop-friendly handling

The taps are specified for steels up to approximately 900 N/mm² tensile strength, covering a wide range of common construction and engineering grades. The solid HSS cutting material resists abrasion and heat better than carbon steel, extending service intervals and lowering lifecycle costs. For users seeking reliable, standards-compliant thread production without extensive setup, this set combines simplicity, robustness, and industry conformity, fitting well into a stocked tooling cabinet or mobile service kit.

FAQ

What thread form does this set produce?
The set produces a Whitworth pipe thread G 1/2" (14 tpi) in accordance with DIN ISO 228, suitable for standard pipe fittings.

Can the taps be used in blind holes?
Yes. The two-piece configuration is specified for both through holes and blind holes, allowing controlled depth machining and a clean thread profile.

Which materials are appropriate for these taps?
The taps are made from HSS and specified for steels with tensile strength up to approximately 900 N/mm²; they are therefore suitable for common engineering steels.

What is the advantage of the two-piece set?
Using a roughing tap followed by a finishing tap reduces cutting forces, improves thread finish and extends tool life compared with single-step tapping.

What is the article number or SKU for ordering?
The article number is 2000867095NW and the item is listed as the TECWERK hand tap set G 1/2" HSS ISO 228 2pc.
