Threading die FANAR Narzynka M18 (N1-121001-0180) for cutting M18 external threads

FANAR Narzynka M18 is a precision threading die designed to cut external M18 metric threads on rods, bolts and shafts. Supplied under model N1-121001-0180, this die is intended for manual or machine-assisted threading operations where repeatable, accurate external thread profiles are required. The tool is made for use in metalworking, maintenance and assembly environments that demand consistent thread geometry for mechanical fastening.

Advantages

This threading die provides accurate M18 thread cutting with a profile suitable for standard metric fasteners. It is compatible with common die holders and can be used in both hand and machine setups, allowing flexible application across shop and field tasks. The die’s design supports consistent thread pitch and form, reducing the need for rework and improving assembly reliability.

Suitable for

• Cutting external M18 threads on rods and shafts
• Repairing or restoring damaged M18 threads on bolts
• Production and maintenance operations requiring metric external threads
• Use with manual die holders and compatible threading machines

Key specifications

• Thread profile: metric external thread M18
• Application: external threading of rods, bolts and shafts
• Compatibility: suitable for manual die holders and machine-assisted threading
• Typical use environments: metalworking shops, maintenance and assembly lines

How to use

Secure the die in a compatible die holder or threading machine spindle. Align the die squarely with the workpiece axis and apply cutting lubricant suitable for the workpiece material. For manual use, start the die by hand to ensure correct engagement, then advance with steady pressure while maintaining alignment. For machine use, set appropriate spindle speed and feed for the material. After cutting, back the die periodically to clear chips and inspect the thread form for correct pitch and fit.

Usage recommendations

Use cutting fluid to reduce wear and improve surface finish; choose lubricant based on the workpiece material (e.g., cutting oil for steel, suitable lubricants for stainless steel or non-ferrous metals). Inspect the die before use for wear or damage and replace if thread form is degraded. When repairing damaged threads, pre-threading with a chasing tool or reaming the shaft to correct diameter may improve results.
