Threading Die FANAR Narzynka M20x1,5 N2-188001-0205 — metric M20×1.5

FANAR Narzynka M20x1,5 (metric M20×1.5) is a handheld threading die for cutting and restoring external metric threads on shafts, rods and pipes. It is designed to be used with a die stock or hand holder to produce precise external threads in workshop and field environments. The tool is intended for metalworking and maintenance tasks where a reliable M20×1.5 external thread is required, including thread repair during assembly and production of new threaded components.

Advantages

The solid construction of the threading die provides stable cutting performance and consistent thread geometry. Its metric M20×1.5 profile ensures compatibility with standard M20 fasteners and fittings. The die is suitable for manual operation with common die stocks and hand holders, offering portability for on-site repairs as well as bench use. Its design facilitates controlled material removal for accurate thread pitch and diameter.

Suitable for

• Cutting new external M20×1.5 threads on round bars, shafts and pipes
• Repairing damaged or worn external threads during maintenance
• Producing threaded components for assembly and mechanical fittings
• Portable on-site threading where power tools are impractical

Key specifications

• Thread system: metric
• Thread size: M20
• Thread pitch: 1.5 mm
• Application: external threading on round profiles (shafts, rods, pipes)
• Operation: manual use with die stock or hand holder
• Typical materials: steel, alloy steel, non-ferrous metals (subject to material hardness and tool suitability)

How to use

Secure the workpiece in a vise so it cannot rotate. Mount the die in a compatible die stock or hand holder, orienting it square to the workpiece axis. If cutting new threads, chamfer the end of the rod slightly to ease engagement. Apply cutting fluid suitable for the work material. Advance the die onto the rotating workpiece or move the die along the stationary bar using steady, even pressure; for manual operation turn the die stock forward a partial rotation then back slightly at intervals to break chips and prevent jamming. Continue until the required thread length is achieved, then reverse the die to remove it. Clean chips and apply a protective coating if required.

Usage recommendations

For best results, use appropriate cutting fluid and check compatibility of the die material with the workpiece. Maintain a firm, square alignment between the die and workpiece to ensure correct thread geometry and extend tool life. For severely damaged threads, consider single-pass roughing followed by a finishing pass to restore accurate dimensions.
