Threading Die (Narzynka) Art-Pol M20×2.0mm

Art-Pol Threading Die (Narzynka) M20×2.0mm is a solid-cutting tool designed for creating or restoring external metric threads with a nominal diameter of 20 mm and a pitch of 2.0 mm. Made for manual use with a die stock or with compatible machine-assisted holders, this die is suitable for work on rods, studs and shafts where accurate M20×2.0 external threads are required. The tool is intended for maintenance, metalworking and repair operations that demand reliable thread form and repeatable dimensional accuracy.

Advantages

The die provides precise thread geometry to ensure proper mating with standard M20×2.0 nuts and threaded components. Its construction supports both manual and machine-assisted operation, offering consistent cutting performance and durability in typical workshop conditions. The tool simplifies thread repair and on-site rethreading tasks, reducing the need to replace worn or damaged fasteners and minimizing downtime.

Suitable for

• Cutting external metric threads on rods, studs and shafts
• Repairing damaged or worn M20×2.0 threads
• Maintenance and mechanical repair work in workshops and industrial settings
• Small-scale production or prototyping where M20×2.0 external threads are required

Key specifications

• Thread type: external metric thread
• Nominal diameter: 20 mm
• Thread pitch: 2.0 mm
• Application: manual or machine-assisted cutting on rods and studs
• Typical material compatibility: steel, alloy steel, stainless steel, and other common metal rods (observe material-specific cutting recommendations)

How to use

Secure the rod or stud in a vise or suitable fixture to prevent rotation. Mount the die in an appropriate die stock or holder, aligning it squarely with the workpiece. Apply cutting fluid suitable for the workpiece material. Start cutting with light, even pressure and rotate the die forward for a few turns, then reverse slightly to break chips and clear debris. Continue this advance-and-back technique until the desired thread length is achieved. After cutting, clean the threaded area and inspect the thread for dimensional and surface quality.

Usage recommendations

Use appropriate cutting lubricant for the workpiece material and avoid excessive force to reduce risk of die breakage. For hardened or abrasive materials, consider pre-drilling or using dies specifically rated for those materials. Regularly clean and inspect the die to maintain cutting performance; store in a dry place to prevent corrosion.
