Threading die left-hand FANAR M16x1.5 N1-111001-0165 — left-hand external die, metric M16x1.5

FANAR left-hand external threading die M16x1.5 is a precision tool for cutting or restoring external metric threads with a left-hand (reverse) 1.5 mm pitch. Intended for use by hand or in a compatible die holder, this die enables formation of M16 threads on shafts and rods where a counter-clockwise thread direction is required. The tool is suitable for workshop repairs, assembly operations and machining tasks that require reliable thread geometry and repeatable results.

Advantages

The die provides accurate thread profile and consistent pitch suitable for mating with standard M16 x 1.5 internally threaded components. Its design allows manual operation or mounting in a die holder to improve control and alignment. The tool's geometry supports efficient material removal and thread restoration while minimising risk of cross-threading when correctly aligned. Manufactured for general maintenance and mechanical use, it is compatible with common steel and non-ferrous materials within recommended cutting parameters.

Suitable for

• Cutting new external left-hand M16 x 1.5 threads on shafts and rods
• Restoring damaged or worn left-hand external M16 x 1.5 threads
• Manual threading with a T-handle or in a die stock/holder
• Maintenance and assembly tasks in mechanical, automotive and industrial applications

Key specifications

• Thread form: metric ISO profile, left-hand
• Thread size and pitch: M16 × 1.5 (external)
• Intended use: manual or die-holder operation for external threading
• Material compatibility: steels and common non-ferrous metals (use appropriate cutting fluid)
• Typical application: cutting or repairing threads on rounds and shafts

How to use

Select a die holder or T-handle that securely seats the die and ensures correct alignment with the workpiece. Clamp the rod or shaft firmly and centre the die on the starting point. Apply suitable cutting fluid to the workpiece to reduce friction and improve chip evacuation. Start the die onto the shaft in the correct orientation for left-hand threading (reverse direction) and advance with steady, even pressure. After several turns, back the die periodically to clear chips and inspect the thread. Continue until the required thread length is achieved, then deburr the thread ends and clean the component.

Usage recommendations

Use appropriate personal protective equipment and the correct cutting lubricant for the workpiece material. For hardened or unusually tough materials, consider pre-drilling to the recommended core diameter and verify material hardness before threading. Ensure the die is mounted square to the shaft to avoid tapered or misaligned threads.
