Thread Tap FANAR G 1/2" DIN-5156B HSSE 800, hand/machine tap

The FANAR G 1/2" DIN-5156B HSSE 800 hand/machine tap is made for cutting internal G (BSPP) 1/2" threads to the DIN‑5156B form. Manufactured from HSSE 800 tool steel, this tap is suitable for use by hand or in machine tapping operations and is intended for general-purpose threading of metals in workshop and industrial environments. The geometry follows the DIN‑5156B profile for parallel pipe threads and is compatible with materials commonly machined with high-speed steel with cobalt tool grades.

Advantages

The HSSE 800 material provides improved hardness and heat resistance compared with standard high-speed steel, extending tool life in demanding cutting conditions. The DIN‑5156B geometry ensures consistent G (BSPP) thread form suitable for sealing and assembly applications where that standard is required. The tap's design allows reliable use both in hand tapping and in machine tapping setups, offering flexibility for different workflow requirements.

Suitable for

• Cutting internal G (BSPP) 1/2" threads in steel, stainless steel and non-ferrous metals
• Workshop and industrial threading operations
• Hand tapping and machine tapping with appropriate holders
• Repair and maintenance tasks requiring DIN‑5156B thread form

Key specifications

• Thread standard: DIN‑5156B (G / BSPP parallel thread)
• Thread size: G 1/2" (internal)
• Material: HSSE 800 (high-speed steel with cobalt)
• Use: Hand and machine tapping compatible
• Application: General-purpose metal threading

How to use

Select an appropriate pilot hole diameter and ensure correct alignment with the workpiece before starting. Use cutting fluid suitable for the workpiece material to reduce friction and heat. For hand tapping, use a tap wrench and apply steady, even pressure, reversing periodically to break chips. For machine tapping, secure the tap in a proper holder and run at recommended speeds and feeds for HSSE tools and the specific workpiece material. After tapping, clean chips from the thread and inspect the thread profile for conformity to DIN‑5156B.

Usage recommendations

Use cutting fluid for extended tool life and clearer chip evacuation. Match tap speed to material hardness—slower speeds for stainless steels and harder alloys. Replace taps showing wear or deformation to maintain thread accuracy and thread quality in assemblies.
