Threading Die FANAR Narzynka calowa 3/8" N1-121001-3129 — imperial pipe/thread die 3/8"

FANAR Narzynka calowa 3/8" (imperial pipe/thread die 3/8") is a solid external threading die made for cutting or renewing 3/8" imperial external threads on pipes, bolts and rods. Designed for use with standard die stocks or holders, the tool supports routine metalworking, maintenance and repair operations where imperial thread form and size are required. The compact, robust construction ensures consistent engagement with workpieces and accurate thread profile reproduction when used with appropriate equipment and cutting conditions.

Advantages

The die delivers precise, repeatable external threads for 3/8" nominal diameters, reducing rework and improving fit between threaded components. Its hardened construction resists wear during repeated use, while the compact form factor makes it easy to position in a die stock or holder. The product is compatible with common imperial-thread applications, enabling repairs and machining without conversion to metric tooling.

Suitable for

• Cutting or renewing external 3/8" imperial threads on pipes
• Repairing damaged bolt or rod threads sized 3/8"
• General metalworking and maintenance tasks requiring imperial threads
• Use with compatible die stocks, holders and hand-operated threading tools

Key specifications

• Thread type: external imperial (3/8" nominal diameter)
• Application: cutting and restoring external threads on pipes, bolts and rods
• Construction: hardened threading die for wear resistance
• Compatibility: designed for standard die stocks and holders supporting imperial dies
• Form factor: compact round die suitable for hand or machine-assisted threading

How to use

Mount the die securely in a compatible die stock or holder, aligning the cutting face with the workpiece. Apply appropriate cutting lubricant to the workpiece and start the die square to the axis of the pipe, bolt or rod. Turn the die with steady force, advancing gradually and backing off periodically to clear chips. Continue cutting until the required thread length is achieved, then remove the die and clean the threaded area. Inspect the thread profile for fit and clear any remaining burrs or debris before assembly.

Usage recommendations

Use suitable cutting fluid and maintain alignment between die and workpiece to prolong die life and ensure clean threads. Avoid excessive force and clear chips often to prevent jamming. For best results on hardened or abrasive materials, consider light passes and intermediate inspection.
