Thread Tap FANAR G 3/8" DIN-5156C R40 HSS-E TiN for pipe threads

FANAR thread tap G 3/8" DIN-5156C R40 HSS-E TiN is a precision tool designed for producing G (BSPP) 3/8" parallel pipe threads according to DIN-5156C. Manufactured from high-speed steel with cobalt (HSS-E) and finished with a titanium nitride (TiN) coating, this tap provides consistent thread form and dimensional accuracy for plumbing, hydraulic and general metalworking applications. The geometry complies with DIN-5156C standard requirements for pipe-thread cutting and forming processes, making it suitable for both manual and machine tapping operations.

Advantages

The HSS-E material delivers improved red-hardness and toughness compared with standard high-speed steel, reducing chipping during interrupted cuts. The TiN coating enhances surface hardness and wear resistance while promoting smoother chip evacuation and reduced friction. Conformance to DIN-5156C and a dedicated R40 flute/profile ensure reliable thread shape and repeatable results. The tool’s design supports use in a variety of workpiece materials common in plumbing and hydraulics.

Suitable for

• Cutting or forming G (BSPP) 3/8" parallel pipe threads in metal parts
• Manual tapping with a tap wrench or machine tapping on a tapping head
• Plumbing, hydraulic system assembly and maintenance
• General metalworking where DIN-5156C G 3/8" threads are required

Key specifications

• Standard compliance: DIN-5156C thread profile
• Material: high-speed steel with cobalt (HSS-E)
• Surface finish: titanium nitride (TiN) coating
• Flute/profile: R40 geometry for pipe threads
• Intended use: manual and machine tapping

How to use

Select the correct pilot hole diameter and prepare the workpiece by deburring and securing it in a fixture or vice. For manual tapping, use a suitable tap wrench and apply steady, even pressure while turning; back off periodically to break chips. For machine tapping, ensure correct spindle speed and feed for the workpiece material and use appropriate tapping holders or floating heads to maintain alignment. Apply a suitable cutting lubricant compatible with HSS-E taps to extend tool life and improve surface finish. Inspect formed threads for dimensional conformity and clean chips from the workpiece after tapping.

Usage recommendations

Use moderate cutting speeds and proper lubrication when working with stainless steels or other hard alloys to minimise wear. For interrupted cuts or thin-walled parts, reduce feed and consider multiple light passes. Store the tap in a protective case to prevent damage to the TiN coating and cutting edges.
