Fanar G 3/8" Pipe Tap NGRA/2-P DIN 5157 HSSE INOX

The Fanar G 3/8" pipe tap, model NGRA/2-P, is a professional-grade threading tool engineered for high-precision cutting of gas pipe threads. Manufactured in accordance with DIN 5157 standards, this tool is constructed from high-speed cobalt-enriched steel (HSSE), which provides exceptional thermal stability and structural integrity when working with challenging materials. Its specialized geometry is optimized for the demanding requirements of stainless steel machining, ensuring clean, accurate threads and extended tool life in industrial environments.

Advantages

The primary benefit of this tap is its superior material composition, which allows for reliable performance in tough INOX applications where standard tools might fail. The HSSE steel construction offers excellent resistance to heat and wear, maintaining cutting edge sharpness over long production cycles. Furthermore, the precise design according to DIN 5157 ensures that every thread cut meets strict industrial tolerances, reducing the risk of leaks or assembly issues in gas piping systems.

Suitable for

• Cutting internal G 3/8" threads in stainless steel pipes
• Industrial gas piping installations
• High-volume threading operations in workshops
• Maintenance and repair of stainless steel hydraulic components

When it may not be suitable

This tool is specifically optimized for stainless steel and may not provide the most efficient performance when used on softer materials like aluminum or plastics, where different rake angles are typically preferred. It is also not intended for manual threading in non-rigid setups, as the high-performance geometry requires stable machine conditions to prevent tool breakage.

Key specifications

• Thread type: G 3/8" (Pipe thread)
• Material: HSSE (High-Speed Steel with Cobalt)
• Standard: DIN 5157
• Application: Stainless steel (INOX)
• Design: NGRA/2-P

How to use

To achieve optimal results, ensure the workpiece is securely clamped in a rigid machine setup. Use a high-quality cutting oil specifically formulated for stainless steel to reduce friction and heat buildup during the threading process. Align the tap perfectly with the pre-drilled hole and apply consistent pressure. It is recommended to use a synchronized tapping head if available to maintain thread accuracy and prevent damage to the tap or the workpiece.

What to consider before purchase

• Verify that the G 3/8" thread size matches your specific piping requirements
• Ensure your machine setup provides sufficient rigidity for HSSE tooling
• Confirm that your coolant system is compatible with stainless steel machining

Usage recommendations

Always monitor the cutting speed and torque settings to match the specific grade of stainless steel being machined, as excessive speed can lead to premature wear of the cutting edges.
