Threading Die FANAR Narzynka M20 — external thread tool M20, solid round die

FANAR Narzynka M20 is a solid round external threading die designed for cutting M20 metric threads on rods and shafts. Made for both manual and machine-assisted operations, the tool delivers accurate thread profiling suitable for repair, assembly and fabrication tasks. Its compact, solid construction provides stability during cutting and helps maintain concentricity when producing M20 external threads.

Advantages

The solid round die offers consistent thread geometry and durable cutting edges that withstand repeated use in workshop or on-site conditions. Its design allows for integration with standard die stocks and holders, and the robust material composition reduces the risk of chipping or premature wear. The tool is versatile for both single-piece repairs and small-batch production work where M20 external threads are required.

Suitable for

• Repairing damaged M20 threads on shafts and rods
• Cutting new M20 external threads for assembly and fabrication
• Maintenance work in mechanical workshops and industrial sites
• On-site threading where a compact, portable die is needed

Key specifications

• Thread size: M20 (metric external thread)
• Type: solid round die for external threading
• Usage: manual or machine-assisted threading
• Form factor: compact round die compatible with standard die holders
• Material characteristics: hard metal construction with durable cutting edges for repeated use

How to use

Mount the round die in a compatible die stock or holder, ensuring the orientation matches the lead-in chamfer for correct thread engagement. Secure the workpiece in a vise or fixture to prevent rotation, apply cutting fluid or lubricant to the rod or shaft, and start cutting with steady, even pressure. Periodically reverse the die slightly to break and clear chips, and reapply lubricant as needed to maintain cutting performance and extend tool life.

Usage recommendations

For best results, use appropriate cutting fluid and select a die holder that provides stable alignment. Inspect the workpiece for straightness before threading and remove burrs or nicks at the start point. For hardened or coated materials, confirm material compatibility and consider pre-drilling or softening treatments to avoid excessive wear.
