Fanar C4-525301-0080 M8 Spiral Flute Machine Tap DIN 371C HSSE-PM TiCN

The Fanar M8 spiral flute machine tap is a high-performance threading tool engineered for precision and durability in industrial metalworking. Manufactured from premium HSSE-PM powder steel and finished with a specialized TiCN coating, this tap offers superior wear resistance and extended tool life. Designed to meet DIN 371C standards, it features a 45-degree helix angle specifically optimized for efficient chip evacuation when cutting threads in blind holes.

Advantages

The primary advantage of this machine tap lies in its advanced material composition and geometry. The use of HSSE-PM powder steel provides a fine-grained structure that significantly enhances toughness and heat resistance compared to standard high-speed steels. The TiCN coating further reduces friction during the cutting process, allowing for higher cutting speeds and improved surface finish quality. Its robust design ensures consistent thread accuracy and stability, even when working with challenging materials.

Suitable for

• Threading blind holes in steel and alloyed materials
• Industrial CNC machining centers
• High-volume production environments
• Applications requiring high thread precision

When it may not be suitable

This tap is specifically optimized for blind hole applications due to its spiral flute design. It may not be the most efficient choice for through-hole threading, where straight flute taps are typically preferred for better chip control. Additionally, it is not intended for use on extremely hardened materials that exceed the recommended hardness range for HSSE-PM tools.

Key specifications

• Thread size: M8
• Material: HSSE-PM powder steel
• Coating: TiCN
• Standard: DIN 371C
• Helix angle: 45 degrees
• Application type: Blind holes

How to use

To achieve optimal results, ensure the workpiece is securely clamped and the tap is perfectly aligned with the pre-drilled hole. Use a high-quality cutting fluid to facilitate chip evacuation and reduce heat buildup. When starting the threading process, apply consistent pressure and ensure the machine feed rate is synchronized with the tap pitch. Regularly inspect the tap for signs of wear or chip buildup to maintain thread quality and prevent tool breakage.

What to consider before purchase

• Verify the required thread size and pitch for your specific application
• Ensure your machine setup supports the use of DIN 371C standard taps
• Check the compatibility of the TiCN coating with your target material
• Confirm that the blind hole depth is sufficient for the tap's lead chamfer

Usage recommendations

Always use appropriate lubrication to extend the service life of the TiCN coating and ensure clean thread formation. Monitor the torque levels during operation to prevent premature tool failure.
