Bàn ren ngoài (tạo ren ngoài) HSS - NPT 1/16 x 27

• dùng cho ứng dụng thông dụng
• non abrasive material up to 800 N/mm²
• unalloyed and low alloyed thép
• for cutting ren ngoài

1. Prepare the rod: Choose a rod with the correct outer diameter (or pipe) and apply a slight chamfer to the end.
2. Clamp the tool: Insert the Bàn ren ngoài (tạo ren ngoài) into the appropriate Tay quay bàn ren (holder) and fix it securely.
3. Lubrication: Apply a suitable Kem cắt gọt ren or cutting oil to the rod and the die to reduce friction and heat.
4. 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.
5. Cleaning: After cutting, remove all chips and thoroughly clean the ren ngoài and the die.

Q1: What is the difference between a Bàn ren ngoài (tạo ren ngoài) and a tap?

A1: A Bàn ren ngoài (tạo ren ngoài) (or Die Ring) is used for cắt ren of ren ngoài (on rods or pipes). A tap, on the other hand, is used to cut ren trong in holes. Both tools are essential for cắt ren.

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 Kem cắt gọt ren for cắt ren?

A4: The use of Kem cắt gọt ren or oil is crucial for extending the die's lifespan. It reduces friction and the resulting heat, leading to better surface quality of the ren ngoài and easier chip removal.

Q5: Can I use this die for stainless thép?

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 thép or stainless thép ($> 800 \text{ N/mm}^2$), 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 Bàn ren ngoài (tạo ren ngoài)?

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.
