NKP 17 X 1.5 MM 1.1/2 Inch Dia High-Speed Steel Circular Die

1. Size and Thread Specifications:
   • Diameter: 1.1/2 Inches (approximately 38.1 mm). The outer diameter of the die allows it to fit into die holders or die stocks, making it easy to handle and operate during threading tasks. The size of the die makes it suitable for larger threading projects.
   • Thread Size: 17 X 1.5 mm. This denotes the nominal thread diameter of 17 mm and a thread pitch of 1.5 mm:
     • 17 mm: This is the nominal diameter of the thread that the die creates, making it ideal for medium-sized fasteners. It is a common size for bolts, rods, and threaded components in industrial and automotive applications.
     • 1.5 mm: The thread pitch refers to the distance between adjacent threads, and a 1.5 mm pitch is classified as a medium thread pitch, which provides a balance between strength and precision. It is commonly used in mechanical and industrial applications where a moderate holding power is needed.
2. Material:
   • High-Speed Steel (HSS): The die is made from high-speed steel, a material known for its superior hardness, wear resistance, and heat durability. HSS is capable of maintaining its cutting edge even at high temperatures, ensuring long-lasting performance in tough working conditions. This material is perfect for tools used in threading operations, where durability and precision are key.
3. Design and Construction:
   • Circular Die Shape: The die is designed as a circular disk, with the cutting edges located along its outer circumference. This shape allows for even and consistent thread cutting on cylindrical workpieces.
   • Central Hole: The die features a central hole that ensures proper alignment and guidance of the workpiece during threading. This design helps to create accurate and consistent threads.
   • Multiple Cutting Edges: The circular die has multiple sharp, precision-cut edges around its circumference that efficiently cut threads into the workpiece. These cutting edges allow the die to perform effectively without excessive friction, leading to smoother operation.
4. Purpose:
   • Thread Cutting and Repair: The NKP 17 X 1.5 MM die is primarily used to cut external threads on rods, bolts, or pipes, or to restore damaged or worn-out threads. It is an essential tool for mechanical assemblies where threaded components need to fit perfectly together.
   • Versatility: This die can be used across a wide range of applications, from industrial and automotive repairs to general metalworking. It is ideal for professionals working in manufacturing or maintenance, as well as for hobbyists and DIY enthusiasts.
5. Features:
   • Precision Threading: This die is engineered for high precision. The tight tolerances ensure that threads are cut with accuracy, resulting in threads that fit securely with nuts or other fasteners, which is essential for the mechanical integrity of the assembly.
   • Durability and Heat Resistance: HSS construction ensures that the die can withstand high temperatures and wear over time, providing a longer tool life even with heavy use.
   • Efficient Thread Cutting: The die is designed to create threads quickly and efficiently, minimizing friction and heat buildup during use. This leads to smoother operation and helps maintain the die's cutting edge for longer.
6. Applications:
   • Industrial and Manufacturing: This die is commonly used in industrial manufacturing processes where external threads are frequently created or repaired. It is ideal for threading bolts, rods, and other fasteners in machinery, equipment, and structural components.
   • Automotive and Mechanical Repairs: In automotive repair shops and mechanical workshops, this die is used for threading or repairing bolts, rods, and other components critical to automotive engines, transmissions, and other systems.
   • Metalworking: It is also widely used in metalworking and machining for threading custom components or restoring damaged threads.
   • DIY and Home Projects: Hobbyists and DIY enthusiasts who work on metalworking projects at home can benefit from this die when threading rods or bolts for custom projects or repairs.
7. Advantages:
   • Long-Lasting Durability: The high-speed steel material provides superior wear resistance and longevity, which makes the die suitable for continuous use in demanding conditions.
   • Precise Thread Formation: The die ensures accurate, clean threads, which are essential for creating secure and reliable threaded connections.
   • Versatile Use: This die can be used in a wide range of applications, from cutting new threads to repairing worn-out ones. Its versatility makes it an invaluable tool for professionals and DIYers alike.
   • Efficiency: With its sharp cutting edges and smooth operation, the die can cut threads more efficiently and quickly, saving time and effort on threading tasks.
8. Handling and Usage:
   • Die Stock/Holder: The NKP 17 X 1.5 MM circular die is designed to be used with a die stock or die holder. The die is mounted in the holder, which provides the user with leverage and control during the threading process.
   • Threading Process: To use the die, align it with the workpiece and rotate it while applying light, consistent pressure. The die cuts the threads into the workpiece as it is turned, either creating new threads or restoring damaged ones.
   • Repairing Threads: When using the die for thread repair, simply align it with the existing threads and rotate it to restore the damaged or worn threads. The die will re-cut the threads to their original size and pitch, making the fastener usable again.

Summary:

The NKP 17 X 1.5 MM 1.1/2 Inch Dia High-Speed Steel Circular Die is a highly durable and efficient tool designed for cutting or repairing external threads with a 17 mm nominal diameter and a 1.5 mm pitch. Made from high-speed steel, it offers exceptional wear resistance, heat durability, and long-lasting performance. Ideal for industrial, automotive, mechanical, and metalworking applications, this die ensures precision threading, whether for creating new threads or restoring damaged ones. With its versatile use and reliable performance, it is an invaluable tool for professionals and DIY enthusiasts alike.
