Threading Die (metric) FANAR M12 — solid round die for cutting/repairing M12 threads

FANAR solid round metric threading die for M12 threads is designed for cutting, repairing and restoring external M12 metric threads on rods, studs and fasteners. The tool is compatible with standard die holders and can be used manually or with suitable machines to achieve a consistent thread profile and pitch for maintenance and assembly operations.

Advantages

The solid construction ensures dimensional stability and durability during repeated use. Precision-ground cutting edges provide accurate thread geometry and consistent pitch, reducing the need for rework. The round die format allows simple mounting in common die holders and offers easy alignment on the workpiece. Its design supports both cutting new threads and restoring damaged or worn external threads.

Suitable for

• Cutting new external M12 metric threads on rods and studs
• Repairing or restoring damaged M12 threads on fasteners and bolts
• Maintenance tasks in workshops and service departments
• Use with manual die holders or suitable machines for production and assembly

Key specifications

• Thread standard: metric
• Thread size: M12
• Type: solid round die
• Suitable for external threading on rods, studs and fasteners
• Compatibility: fits standard round die holders and machines designed for round dies

How to use

Secure the round die in an appropriate die holder according to the holder manufacturer's instructions, ensuring correct orientation and firm clamping. Place the die on the prepared end of the rod or stud and advance slowly while applying steady rotation to cut or restore the thread. Use cutting oil or lubricant suitable for the material being threaded to reduce friction and improve chip evacuation. Reverse the die periodically to break chips and check thread fit with a mating nut or gauge. After finishing, clean chips from the die and workpiece and inspect the thread for correct form and pitch.

Usage recommendations

Use appropriate personal protective equipment and select cutting lubricant matched to the workpiece material. For severely damaged threads, pre-cut a lead or use a tap/die sequence to correct alignment before final threading. Store the die in a dry place to prevent corrosion and check cutting edges before each use.
