Thread Tap FANAR G 1/8 DIN-5156C R45 HSSE-PM HL MASTERTAP — hand tap G1/8

FANAR thread tap G 1/8 DIN-5156C R45 HSSE-PM HL MASTERTAP — hand tap G1/8 is a precision hand tap designed to produce G 1/8 (BSPP) parallel pipe threads. Manufactured to DIN-5156C geometry from high-speed steel HSSE-PM and finished with a high-lubricity (HL) coating, this tap is intended for controlled manual tapping and guided machine tapping. It provides consistent thread form for general-purpose metals and steels where G 1/8 threads are required.

Advantages

The HSSE-PM substrate offers high wear resistance and good toughness for improved tool life in intermittent cutting and harder materials. The DIN-5156C geometry with R45 (45° chamfer) ensures reliable thread start and gradual engagement, reducing the risk of breakage during hand tapping. The high-lubricity finish improves chip evacuation and reduces friction to support smoother cutting and easier tap withdrawal. Designed for G 1/8 (BSPP) thread form, the tap gives precise, repeatable thread dimensions when used with appropriate drilling and tapping practices.

Suitable for

• Creating G 1/8 (BSPP) parallel threads in steel and general-purpose metals
• Manual hand tapping and guided machine tapping operations
• Repairing or replacing worn G 1/8 threads in assemblies
• Prototyping and small-batch production where controlled thread quality is required

Key specifications

• Thread type: G 1/8 (BSPP) parallel pipe thread
• Standard geometry: DIN-5156C
• Chamfer: R45 (45°) for gradual entry
• Material: HSSE-PM (high-speed steel, powder metallurgy)
• Finish: high-lubricity (HL) coating
• Intended use: hand tapping and guided machine tapping

How to use

Select the correct pilot hole diameter and ensure the workpiece is securely clamped and aligned. Use cutting fluid appropriate for the workpiece material to reduce friction and improve chip control. Start the tap square to the hole and advance slowly to engage the chamfered entry. For hand tapping, use a suitable tap wrench and maintain steady, even pressure; reverse the tap periodically to break chips and clear the flute. For guided machine tapping, use proper speed and feed settings recommended for HSSE-PM tools and the workpiece material.

Usage recommendations

Use appropriate cutting fluid for steels and general-purpose metals, avoid excessive side loading during hand tapping, and clear chips frequently. Inspect tapped threads for form and fit; replace the tap if signs of wear or chipping appear to maintain thread quality.
