Thread tap FANAR G 1/8" NGRA/2-P DIN-5157 HSSE INOX A2-225801-3123

FANAR G 1/8" NGRA/2-P DIN-5157 thread tap in HSSE INOX is a two-flute parallel (G / BSPP) internal threading tool designed for cutting G 1/8" internal threads in stainless and high-alloy steels. Manufactured to DIN-5157 geometry, this tap provides controlled cutting action and improved chip evacuation due to its NGRA/2-P two-flute configuration. It is suitable for both hand and machine tapping in metalworking and repair environments where corrosion-resistant materials and high-strength alloys are present.

Advantages

The HSSE INOX material offers enhanced wear resistance and toughness when working with stainless and high-alloy steels, reducing risk of premature tool failure. The NGRA/2-P two-flute design ensures efficient chip clearance and lowers cutting forces, which contributes to more stable thread formation and reduced tool breakage. Compliance with DIN-5157 thread form and tolerances supports consistent thread quality and interchangeability with fittings and components specified for G (BSP parallel) threads.

Suitable for

• Cutting G (BSPP) 1/8" internal threads in stainless and high-alloy steels
• Manual hand tapping and machine tapping operations
• Maintenance, repair and renovation work in plumbing, hydraulics and industrial assemblies
• Small-batch production where corrosion-resistant threads are required

Key specifications

• Thread form: G (BSP parallel) 1/8" to DIN-5157
• Flute configuration: two flutes (NGRA/2-P)
• Material: HSSE INOX (high-speed steel with enhanced properties for stainless steels)
• Application: internal threading (tapping) in stainless and high-alloy steels
• Intended use: suitable for hand and machine tapping

How to use

Select the correct drill size for the G 1/8" thread according to standard tapping charts, secure the workpiece, and ensure alignment between tap and hole. For machine tapping, set appropriate spindle speed and feed based on material and tap size; for hand tapping, use a suitable tap wrench and apply steady, controlled torque. Use cutting fluid recommended for stainless or high-alloy steels to improve chip evacuation and reduce heat. Reverse the tap periodically to break chips and clear the flutes.

Usage recommendations

For longest tool life and consistent thread quality, use appropriate cutting lubricant for stainless steels, maintain correct alignment during tapping, and avoid excessive feed or torque. When tapping deep holes, clear chips frequently and consider peck tapping cycles on machines. Inspect threads and deburr as needed to ensure fit with mating parallel (G) fittings.
