Fanar UNC 3/8-16 DIN 371B HSSE TiN Machine Tap

The Fanar UNC 3/8-16 DIN 371B HSSE TiN machine tap is a high-performance threading tool engineered for precision and durability in industrial metalworking environments. Manufactured from high-speed steel with cobalt (HSSE), this tap features a titanium nitride (TiN) coating that significantly enhances surface hardness and reduces friction during the cutting process. This design ensures consistent thread quality and extended tool life, even when working with demanding materials.

Advantages

The primary benefit of this machine tap is its superior wear resistance provided by the TiN coating, which allows for higher cutting speeds and improved heat dissipation. The HSSE material composition offers excellent toughness, preventing premature chipping or breakage during operation. Furthermore, the DIN 371B geometry is optimized for efficient chip evacuation, which helps maintain accuracy and prevents thread damage during the tapping cycle.

Suitable for

• Creating precise UNC 3/8-16 threads in steel and non-ferrous metals
• Professional machining and industrial manufacturing applications
• CNC and manual tapping operations
• High-volume production environments requiring consistent thread tolerances

When it may not be suitable

This tap may not be suitable for extremely hardened steels or specialized exotic alloys that require carbide tooling for effective penetration. It is also not intended for hand-tapping applications where the specific shank geometry of DIN 371B is not supported by the machine setup.

Key specifications

• Thread type: UNC 3/8-16
• Material: HSSE (High-Speed Steel with Cobalt)
• Coating: TiN (Titanium Nitride)
• Standard: DIN 371B

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 reduce friction and facilitate chip removal. Set the machine to the appropriate speed and feed rate for the material being processed. After the tapping process is complete, reverse the rotation carefully to withdraw the tap without damaging the newly formed threads.

What to consider before purchase

• Verify that the UNC 3/8-16 thread specification matches your project requirements
• Ensure your machine setup is compatible with the DIN 371B shank dimensions
• Check that the material hardness of your workpiece is within the recommended range for HSSE tools

Usage recommendations

Always inspect the tap for signs of wear or damage before each use. Proper lubrication is essential to maximize the lifespan of the TiN coating and ensure the highest thread quality.
