Threading Die FANAR Narzynka M12 N1-121001-0120 — for cutting/restoring M12 threads

FANAR Narzynka M12 threading die (model N1-121001-0120) is a hand or machine-operated tool for cutting and restoring external metric threads sized to M12. Manufactured for general metalworking and maintenance tasks, this die forms a precise thread profile suited to fasteners, bolts and rods requiring M12 external threads. It is compatible with typical die holders and machines designed for round external dies and is intended for use on steel and similar ferrous and non-ferrous materials where a standard M12 thread is required.

Advantages

The FANAR M12 die produces uniform thread geometry and consistent pitch, reducing the need for rework. Its design allows both manual use with standard die stocks and machine use where round dies are supported, offering flexibility across repair and production operations. The die delivers repeatable results for restoring damaged threads and for cutting new external threads with reliable dimensional accuracy.

Suitable for

• Cuts and restores external M12 threads on bolts and rods
• Maintenance and repair of threaded components
• Metalworking shops and on-site service work
• Use with manual die holders and compatible threading machines

Key specifications

• Thread size: M12 (external metric)
• Thread form: standard metric profile
• Application: cutting and restoring external threads
• Compatibility: designed for use with round die holders and machines accepting external dies
• Typical materials: steel and similar metals suitable for threading

How to use

Select a suitable die holder or machine that accepts round external dies and secure the FANAR M12 die according to the holder manufacturer's instructions. Prepare the workpiece by ensuring the rod or bolt is clean, free of burrs and correctly centered. For cutting new threads, apply a suitable cutting lubricant to reduce friction and heat. Engage the die with steady pressure and rotate evenly to cut the thread, reversing periodically to clear chips. For restoring damaged threads, start carefully to align the die with the existing thread and proceed slowly until the thread profile is reformed.

Usage recommendations

Use appropriate cutting fluid for the material being threaded, maintain alignment to avoid cross-threading, and inspect threads with gauges or mating fasteners to verify fit. Replace the die if it shows excessive wear or damage to ensure consistent thread quality.
