Threading Die FANAR Narzynka M7 hand tool for cutting M7 threads

FANAR Narzynka M7 is a hand-operable threading die designed for cutting and restoring external M7 metric threads on rods, studs and shafts. The tool is intended for manual use in workshops or on-site repairs where forming or repairing medium-fine external threads is required. Constructed to work with standard M7 thread dimensions, it provides a practical option for occasional or professional thread cutting tasks without the need for powered machinery.

Advantages

The die offers straightforward manual operation and is compatible with common hand die stocks and holders, enabling controlled cutting and easy thread restoration. Its geometry is suitable for producing consistent M7 thread profiles, reducing the need for multiple passes when used with appropriate cutting lubricant. The compact hand-tool format makes it convenient to carry and use in confined spaces or for field service work.

Suitable for

• Cutting external M7 metric threads on rods and shafts
• Repairing damaged or worn M7 threads on studs and fasteners
• Workshop thread forming and maintenance tasks
• On-site machinery or equipment repairs requiring manual threading

Key specifications

• Thread profile: Metric (M) external thread for M7 size
• Operation: Manual, designed for use with a hand die stock or holder
• Application: Cutting and restoring external threads on rods, studs and shafts
• Typical use environment: Workshop and field repairs

How to use

Secure the die in a compatible hand die stock or holder and align it squarely with the workpiece. Apply suitable cutting lubricant to the rod or shaft to reduce friction and improve chip evacuation. Start the cut by feeding the die onto the workpiece with even pressure, turning the tool clockwise for right-hand threads and reversing periodically to break chips. Continue until the desired thread length is reached, then back off while maintaining alignment to avoid thread damage. After cutting, clean away swarf and inspect the thread for correct form and fit.

Usage recommendations

Use appropriate cutting fluid for the material being threaded, clamp the workpiece securely to prevent slippage, and ensure the die is properly aligned before starting. For hardened or plated materials, perform trial cuts on scrap to confirm the procedure and reduce the risk of tool damage.
