Square Die HSS - G (BSP) 3/4 x 14

The square die is a special form of die, characterized by its square or rectangular outer shape. Unlike the widely used round dies today, which are used in a suitable round die stock or machine holder, the square die was formerly the standard for manual cutting of external threads, especially pipe threads.

A Piece of Craft History in Your Workshop

Its history dates back to the beginnings of industrial manufacturing and craftsmanship, when threads were primarily cut by hand. The square shape allowed the die to be gripped directly with an adjustable die stock or a wrench, thus manually applying the necessary force for the cutting process. It was the workhorse of installers and locksmiths before round dies and machine threading methods took over.

Even if it is used less frequently today, the square die remains a symbol of solid craftsmanship and reliability. It is often the first choice when it comes to repairing older systems, working in confined spaces, or producing specific pipe threads that require special control.

This VÖLKEL die is your specialist when you need to produce durable and tight pipe threads according to the British Standard Pipe (BSP) norm. With the nominal size G (BSP) 3/4 x 14, it precisely solves the challenge of cutting this specific thread on pipes or fittings. Compliance with tolerance class A (factory standard) ensures high fitting accuracy, which is crucial for the tightness of pipe connections.

It is ideal when:

• You are working on existing pipe installations where BSP threads are prevalent.
• You have limited space and need a compact, manually operable tool.
• You are looking for a robust and durable tool that maintains its shape even with heavy use.

The VÖLKEL square die offers you specific advantages that make it a valuable addition to your workshop equipment:

• Proven Precision for Pipe Threads: The die is specifically designed for pipe thread G (BSP) 3/4 x 14. This cylindrical pipe thread, unlike conical NPT threads, is known for its parallel flank shape, which allows for excellent sealing by means of a gasket (e.g., hemp, Teflon tape). The precise manufacturing according to factory standard with tolerance A guarantees you threads with exact flank shape and pitch.
• Versatility in Application: This HSS-G die is optimally suited for general use and reliably cuts threads in easily machinable materials up to 800 N/mm², including unalloyed and low-alloy steels. It thus covers a wide range of materials commonly used in pipe installation.
• Robust Construction for Heavy Use: The square shape and solid HSS-G material (ground) make this die extremely durable. It withstands high forces and is less prone to deformation than thinner-walled round dies during manual use. This ensures a long lifespan and consistent performance.
• Optimal Power Transmission and Handling: The square shape allows for a secure and non-slip grip in the appropriate die stock or with a suitable wrench. This is particularly advantageous for manual cutting, as the applied force is efficiently and controllably transferred to the workpiece, leading to cleaner cutting results.
• Quality and Tradition from VÖLKEL: VÖLKEL is an established name in the field of threading tools and stands for decades of experience and German engineering. With this die, you acquire a product based on proven standards and high manufacturing quality.

To unleash the full potential of your VÖLKEL Square Die and maximize its lifespan, we recommend the following accessories:

• Matching Die Stock for Square Dies: A robust, adjustable die stock that can securely hold your die's 51.5 mm outer diameter is essential for manual application.
• High-Quality Cutting Oil: The use of a special cutting oil is essential. It reduces friction, dissipates heat, and improves chip evacuation. The result is not only cleaner and more precise threads but also a significantly longer lifespan for your die.

1. 1. What does G (BSP) 3/4 x 14 mean for pipe threads?

   G (BSP) stands for "British Standard Pipe Parallel". "3/4" is the nominal pipe size, referring to the inner diameter, not the outer diameter of the thread. "14" indicates the number of threads per inch. It is a cylindrical thread that requires a seal.

2. 2. Can I use this die with a standard die stock for round dies?

   No, this square die requires a special type of die stock designed for square dies. Standard die stocks for round dies are not compatible. Make sure to use a suitable holder to avoid damage to the tool or unsafe work.

3. 3. What materials is this die best suited for?

   It is optimal for easily machinable materials up to 800 N/mm², especially unalloyed and low-alloy steels. For harder or high-alloy materials, such as certain stainless steels, a specialized die with a different geometry or coating, possibly made of PM-HSS-E or carbide, would be more effective.

4. 4. What is the advantage of a square die over a round die?

   The main advantage lies in the more robust construction and better power transmission during manual use, especially with stubborn materials or repairs under difficult conditions. The square shape offers a very stable grip in the die stock or with a wrench, which minimizes slipping and allows for more precise cuts. It is ideal for jobs where traditional, powerful manual labor is required.
