Threading die Topex Narzynka M5 14A305 — for cutting M5 external threads

Topex Narzynka M5 (14A305) is a hand threading die designed for cutting and restoring external M5 metric threads on rods and bolts. Made for manual use with appropriate die stocks or holders, this threading die is intended for metalworking, maintenance and workshop repair tasks where precise M5 external threads are required. The tool is compatible with standard M5 thread dimensions and is suitable for use on steel, stainless steel and other common engineering metals within appropriate hardness ranges.

Advantages

The Topex Narzynka M5 offers a compact, hand-operated solution for producing or repairing M5 external threads without the need for power tools. Its construction provides consistent thread geometry and repeatable results when used with a correct die stock and proper technique. The die’s size and form allow for controlled cutting and rethreading in confined workspaces and on-site repair situations.

Suitable for

• Cutting new M5 external threads on rods and studs
• Restoring damaged or worn M5 threads on bolts and threaded bars
• Workshop maintenance and equipment repairs requiring M5 threads
• Small-scale metalworking, prototyping and hobby projects using M5 fasteners

Key specifications

• Thread size: M5 (metric external thread)
• Type: hand threading die for external threads
• Compatibility: designed for use with standard die stocks or holders sized for this die
• Material suitability: intended for use on steel, stainless steel and other common metals (within appropriate hardness limits)
• Form factor: round/standard hand die suitable for manual threading operations

How to use

Secure the die in a compatible die stock or holder, ensuring the cutting edges are properly aligned with the workpiece. Clamp the rod or bolt in a vise to prevent movement and apply cutting fluid appropriate to the material being threaded. Start the die square to the rod and apply steady, even pressure while turning the die stock clockwise to cut threads; reverse slightly at intervals to break chips and clear swarf. Continue until the required thread length is achieved, then back off the die and clean the newly cut threads.

Usage recommendations

Use suitable cutting or tapping fluid to reduce friction and extend tool life. Inspect the workpiece material hardness before threading; avoid using the die on materials harder than recommended for hand dies. For best results, use a die stock that provides firm, square support and periodically clear chips from the cutting area to maintain thread quality.
