VÖLKEL Round Die HSS - NPT 1/16 x 27
This Round Die from VÖLKEL, also known as a Die Ring, is a high-quality NPT Threading Die made from HSS material. It is used for precise Thread Cutting of External Threads according to the American standard for tapered pipe connections (NPT 1/16 x 27). The robust HSS-G construction ensures a long service life and is excellently suited for general use in easy-to-machine steels. Rely on this precise NPT Threading Die to create tight and reliable pipe threads.
Application
- for general use
- non abrasive material up to 800 N/mm²
- unalloyed and low alloyed steel
- for cutting external threads
Step-by-Step Thread Cutting Instructions
- Prepare the rod: Choose a rod with the correct outer diameter (or pipe) and apply a slight chamfer to the end.
- Clamp the tool: Insert the Round Die into the appropriate die stock (holder) and fix it securely.
- Lubrication: Apply a suitable Cutting Paste or cutting oil to the rod and the die to reduce friction and heat.
- Cut the thread: Place the Die Ring straight and slowly turn it onto the rod clockwise (for NPT). Ensure a steady supply of oil and briefly turn back occasionally to break chips.
- Cleaning: After cutting, remove all chips and thoroughly clean the External Thread and the die.

Frequently Asked Questions (FAQ)
Q1: What is the difference between a Round Die and a tap?
A1: A Round Die (or Die Ring) is used for Thread Cutting of External Threads (on rods or pipes). A tap, on the other hand, is used to cut internal threads in holes. Both tools are essential for Thread Cutting.
Q2: What is an NPT thread and how do you recognize it?
A2: NPT stands for "National Pipe Taper" and refers to a tapered pipe thread (taper 1:16). Its conical shape ensures a self-sealing connection, which is particularly important for gas and fluid lines. It is one of the most important Thread Types in the American region.
Q3: What different Thread Types exist and what does NPT stand for?
A3: Many Thread Types exist and can be broadly divided into metric (M), inch threads (like NPT, UNF), pipe threads (like G or R), and special threads (like Tr). NPT is an American tapered pipe thread type used primarily in North America.
Q4: Why should you use Cutting Paste for Thread Cutting?
A4: The use of Cutting Paste or oil is crucial for extending the die's lifespan. It reduces friction and the resulting heat, leading to better surface quality of the External Thread and easier chip removal.
Q5: Can I use this die for stainless steel?
A5: This HSS die is suitable for easy-to-machine materials up to $800 \text{ N/mm}^2$, which includes most unalloyed and low-alloyed steels. For high-alloyed steel or stainless steel ($> 800 \text{ N/mm}^2$), special high-performance dies (e.g., made of HSS-E) with special coatings are typically required to achieve the best results.
Q6: How does this NPT Threading Die differ from other Round Dies?
A6: This die is specifically designed for the tapered NPT profile and not for cylindrical Thread Types. It allows you to cut a precise taper (1:16 taper) on the workpiece, which is essential for the sealing of pipe connections.
