Fanar C2-505601-0030 M3 Spiral Flute Machine Tap DIN 371C HSSE TiCN

The Fanar M3 spiral flute machine tap is a precision-engineered tool designed for high-performance threading operations. Constructed from high-speed steel with cobalt (HSSE) and finished with a titanium carbonitride (TiCN) coating, this tap provides exceptional hardness and heat resistance. Its spiral flute geometry is specifically optimized for efficient chip evacuation, making it a reliable choice for creating internal threads in blind holes where debris management is critical.

Advantages

The primary benefit of this machine tap is its advanced material composition, which significantly extends tool life and maintains thread quality over long production runs. The TiCN coating reduces friction during the cutting process, allowing for higher cutting speeds and improved surface finish on the threaded parts. By facilitating smooth chip removal, the spiral flute design prevents chip jamming, which is a common cause of tap breakage and thread damage in blind hole applications.

Suitable for

• Threading blind holes in steel and non-ferrous metals
• CNC machining and automated production lines
• Precision metalworking requiring high dimensional accuracy
• Applications where consistent thread quality is essential

When it may not be suitable

This tap is specifically designed for blind hole applications and may not be the most efficient choice for through-hole threading, where straight flute taps are often preferred. Additionally, it is optimized for specific material hardness ranges and may not perform optimally in extremely hardened steels or specialized exotic alloys that require dedicated carbide tooling.

Key specifications

• Thread size: M3
• Standard: DIN 371C
• Material: HSSE (High-Speed Steel with Cobalt)
• Coating: TiCN (Titanium Carbonitride)
• Flute type: Spiral flute

How to use

Ensure the workpiece is securely clamped to prevent vibration during the threading process. Use a high-quality cutting fluid or tapping oil to reduce friction and heat, which will further enhance the performance of the TiCN coating. Align the tap perfectly with the pre-drilled hole to avoid misalignment, which can lead to broken taps or oversized threads. Operate the machine at the recommended speed for the specific material being processed to achieve the best results.

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 the material you intend to machine

Usage recommendations

Always monitor the condition of the cutting edges regularly and replace the tap if signs of wear or dullness appear to maintain the integrity of your threaded components.
