FANAR M4x0.5 Threading Die

The FANAR M4x0.5 threading die is a professional-grade precision tool engineered for cutting external metric fine threads on a variety of metal workpieces. Crafted from high-speed steel, this die offers exceptional durability and wear resistance, ensuring consistent performance during demanding machining operations. Its precise geometry allows for the creation of clean, accurate threads, making it an indispensable asset for both industrial manufacturing and precision workshop repairs.

Advantages

This threading die stands out due to its robust construction and high-quality material composition, which significantly extends the tool's service life even under intensive use. The precision-engineered cutting edges facilitate smooth material removal, reducing the risk of thread deformation and ensuring high-quality results. Its design promotes stability during the threading process, allowing for reliable and repeatable thread formation that meets professional standards.

Suitable for

• Cutting external metric fine threads on metal rods or bolts
• Repairing damaged threads on small mechanical components
• Precision machining in industrial and workshop environments
• Maintenance tasks requiring accurate thread sizing

When it may not be suitable

This tool is specifically designed for metric fine threads and will not function correctly on coarse thread profiles or non-metric standards. It is not intended for use on hardened steel or extremely abrasive materials that exceed the hardness capacity of high-speed steel.

Key specifications

• Thread type: Metric fine
• Nominal diameter: 4 mm
• Thread pitch: 0.5 mm
• Material: High-speed steel

How to use

To use the threading die, secure the workpiece firmly in a vise to prevent movement. Place the die into a compatible die stock, ensuring it is seated squarely. Apply a suitable cutting oil to the workpiece to reduce friction and improve surface finish. Begin by applying steady, even pressure while rotating the die clockwise onto the end of the rod. Ensure the die starts straight to avoid cross-threading. Periodically reverse the rotation slightly to break off metal chips, then continue until the desired thread length is achieved.

What to consider before purchase

• Verify that the required thread pitch is exactly 0.5 mm
• Ensure your die stock handle is compatible with the outer diameter of this die
• Confirm the material of your workpiece is suitable for high-speed steel cutting tools

Usage recommendations

Always use high-quality cutting oil during the threading process to maintain tool sharpness and ensure a smooth thread finish. Regularly clean the die to remove metal shavings and store it in a dry, protective case to prevent corrosion.
