Threading Die Art-Pol ARTPOL NARZYNKA M12x1,75mm for M12 metric threads

Hand threading die Art-Pol ARTPOL NARZYNKA M12x1,75mm is a compact tool designed to cut or restore external M12 metric threads with a 1.75 mm pitch on rods, bolts and shafts made of common metals. Manufactured by Art-Pol, this die is intended for use with a compatible die stock or holder to produce straight, accurate threads for maintenance, repair and light fabrication tasks. The design supports manual operation and is suitable for work in workshops, garages and on-site repair situations.

Advantages

This threading die provides consistent thread profile and reliable fit for components requiring M12 x 1.75 external threads. Its hardened cutting edges maintain shape during repeated use, reducing the need for frequent replacement. The standard metric pitch and common size make it easy to integrate into existing tool sets, while compatibility with standard die stocks ensures controlled manual cutting and alignment. The die’s compact form allows access to confined areas where machining tools cannot be used.

Suitable for

• Cutting new external M12 x 1.75 threads on rods and shafts
• Restoring damaged or worn external M12 threads on bolts and studs
• Maintenance and repair tasks in workshops and garages
• Light fabrication and prototype assembly requiring metric external threads

Key specifications

• Thread form: metric ISO external thread
• Nominal size: M12
• Pitch: 1.75 mm
• Intended operation: manual cutting with die stock/holder
• Material compatibility: common metals (e.g., mild steel, alloy steel, some non-ferrous metals)
• Application environment: workshop, garage, on-site repairs

How to use

Select a compatible die stock sized for M12 dies and secure the die in the holder with the cutting side facing the workpiece. Prepare the rod or bolt by chamfering the end slightly to help start the die. Clamp the workpiece securely in a vise to prevent rotation. Apply cutting lubricant appropriate for the workpiece material to reduce friction and improve chip evacuation. Position the die square to the axis of the rod and begin turning the die stock with moderate, steady pressure. After each full turn, back the die slightly to break chips and clear debris, then continue until the desired thread length is achieved. Clean the newly cut threads and inspect fit with a matching nut or gauge.

Usage recommendations

Use appropriate cutting lubricant for the material being threaded and avoid excessive force to prevent die damage or distorted threads; for restoration tasks, examine the existing thread runout and proceed slowly to align the die before full cutting engagement.
