TECWERK Round Die Form B G 3/4" x 14 HSS A – Whitworth pipe thread, HSS

The TECWERK Round Die Form B G 3/4" x 14 HSS A is a solid cutting die for producing Whitworth pipe threads to DIN ISO 228, engineered for reliable performance when machining steels up to approximately 800 N/mm².

• HSS for long tool life and wear resistance
• Whitworth pipe thread G 3/4" x 14 per DIN ISO 228
• Tolerance field A for consistent thread accuracy
• Closed, pre-slotted Form B for stable cutting

High-accuracy threads that reduce assembly rework

The enclosed cutting geometry is designed to deliver consistent thread accuracy, which reduces the need for post-process corrections and minimises assembly rework. Compliance with DIN ISO 228 and the designation tolerance field A mean the threads meet recognised industrial limits for fit and function. For workshops and production lines that require repeatable results, the die’s specification provides a verifiable basis for purchase decisions and quality planning.

Durable HSS construction for extended service life

Manufactured from HSS, the tool offers elevated hardness and toughness for demanding shop-floor use; the material choice supports machining at higher cutting forces and improves resistance to abrasive wear. The closed, pre-slotted Form B balances load distribution during cutting, which helps preserve flank geometry and extends usable life. Where tooling longevity is a factor in total cost calculations, this die delivers a reliable performance-to-cost ratio.

Practical design for standard pipe-thread applications

Configured for the Whitworth pipe thread G 3/4" x 14, this round die suits common hydraulic and plumbing thread requirements and is compatible with standard die stocks for hand or machine-assisted threading. The nominal height 16 mm provides stable engagement with the workpiece while the pre-slotted construction facilitates chip evacuation and reduces risk of jamming. The tool is specified for machining steels up to ≈800 N/mm², making it suitable for a broad range of general-steel components.

FAQ

What thread standard does this die produce?
This die cuts Whitworth pipe threads to DIN ISO 228 specifications, producing a G 3/4" x 14 profile suitable for standard pipe fittings.

Which materials can be machined with the TECWERK Round Die?
The TECWERK Round Die Form B G 3/4" x 14 HSS A is specified for use on steels up to approximately 800 N/mm² tensile strength.

Is the die suitable for production environments?
Yes; the HSS construction and closed, pre-slotted Form B design provide durability and stable cutting behaviour for workshop and light production use.

How does tolerance field A affect assembly?
Threads produced to tolerance field A offer close dimensional control and consistent fit, which supports reliable connections and reduces the likelihood of leaks or loose assemblies.

What is the physical height of the die and why does it matter?
The die has a height of 16 mm, which ensures sufficient engagement for accurate thread formation and helps maintain alignment during hand or machine threading.
