FANAR CZB-31 HSS Tap and Die Set 31-piece M3-M12

The FANAR CZB-31 is a professional 31-piece tap and die set engineered from high-speed steel (HSS) to provide exceptional durability and cutting performance. This comprehensive kit is specifically designed for creating and repairing precise metric threads, covering a range from M3 to M12. It serves as an essential toolset for workshop environments, ensuring that both professional mechanics and dedicated DIY enthusiasts have the necessary components to maintain threaded fasteners and components with accuracy.

Advantages

The primary benefit of this set lies in the high-speed steel construction, which offers superior heat resistance and longevity compared to standard carbon steel tools. The inclusion of a wide variety of sizes ensures that users can handle diverse threading tasks without needing multiple individual sets. The precision-ground cutting edges facilitate clean and accurate thread formation, reducing the risk of cross-threading or material damage during the tapping and threading process.

Suitable for

• Repairing damaged threads on bolts and nuts
• Creating new metric threads in metal components
• General maintenance and automotive repair tasks
• Precision metalworking and workshop fabrication

When it may not be suitable

This set is intended for use on standard metals and may not be suitable for extremely hardened steels or specialized alloys that require carbide tooling. It is not designed for high-volume industrial production lines where automated machinery is required for continuous threading operations.

Key specifications

• Material: High-speed steel (HSS)
• Thread range: M3 to M12
• Set composition: 31 pieces including various taps and dies
• Thread type: Metric

How to use

To use the FANAR CZB-31 set, first select the appropriate tap or die for the required thread size. Ensure the workpiece is securely clamped to prevent movement. When tapping, use a suitable cutting oil to lubricate the tool and clear metal chips frequently by reversing the rotation periodically. When using dies, ensure the tool is started squarely on the rod to maintain thread alignment. Always apply steady, even pressure and avoid excessive force to prevent tool breakage.

What to consider before purchase

• Verify the thread pitch requirements for your specific project
• Ensure you have the correct tap wrench and die stock handles if not included
• Assess the hardness of the material you intend to thread

Usage recommendations: Always clean the tools after use and store them in the provided case to prevent corrosion and damage to the cutting edges. Regularly inspect the taps and dies for signs of wear to maintain consistent thread quality.
