Thread Tap FANAR G 1/8" DIN-5156B HSS-E TiN for G-thread (1/8")

FANAR thread tap for G (BSPP) 1/8" threads manufactured to DIN-5156B standard. This internal parallel thread tap is made from HSS-E (high-speed steel with cobalt) and finished with a TiN (titanium nitride) coating to increase wear resistance and extend tool life. It is suitable for cutting G-thread (1/8") in a range of metals and is intended for both manual and machine tapping in production, maintenance and repair environments.

Advantages

The combination of HSS-E material and TiN coating provides higher heat resistance, improved edge stability and longer service life compared with uncoated high-speed steel taps. Conformance to DIN-5156B ensures consistent thread form and compatibility with industry-standard G (BSPP) fittings. The tap’s geometry allows reliable chip formation and evacuation during through and blind hole tapping when used with appropriate lubrication and drill/tap practices.

Suitable for

• Cutting internal G (BSPP) 1/8" parallel threads in steel and non-ferrous metals
• Manual tapping with tap wrench or T-handle in maintenance and repair work
• Machine tapping in small to medium batch production
• Tapping in assemblies where DIN-5156B thread form is required for compatibility

Key specifications

• Thread type: G (BSPP) parallel internal thread, 1/8"
• Standard: DIN-5156B (taper/parallel/form per standard for internal threads)
• Material: high-speed steel with cobalt (HSS-E)
• Coating: titanium nitride (TiN) for wear resistance
• Application: suitable for manual and machine tapping

How to use

Select the correct pilot hole diameter and ensure workpiece setup is rigid and aligned. Apply an appropriate cutting fluid for the workpiece material. For manual tapping, start the tap square to the hole and advance with steady, controlled turns, using intermittent reverse turns to break chips when necessary. For machine tapping, set proper spindle speed and feed to match material and tap geometry, and use pecking or through-cycle strategies for blind holes. After tapping, clean chips from the thread and inspect the thread form for compliance with DIN-5156B.

Usage recommendations

Use cutting fluids suitable for the base material, avoid excessive speeds in hard alloys, and replace the tap when wear or coating loss affects thread quality. Store taps in protective packaging to prevent edge damage and maintain coating integrity.
