FANAR tap G 3/4" DIN-5156B HSSE 800 — machine tap for G (BSP) thread, MPN D2-111101-3135

FANAR tap G 3/4" manufactured to DIN-5156B standard is a machine tap engineered for producing G (BSP) parallel internal pipe threads. Made from HSSE 800 high-speed steel, this tool is intended for machine tapping operations in industrial and workshop environments where consistent, accurate G 3/4" threads are required. The geometry and finish conform to the DIN-5156B specification for taps, providing compatibility with standard BSP thread gauges and mating components.

Advantages

The HSSE 800 material offers high hardness and wear resistance for extended tool life during repetitive machining cycles. Manufacturing to DIN-5156B ensures predictable thread form and interchangeability with other standard BSP components. The tap is designed for machine use, giving stable cutting performance and reduced tendency to break under correct operating conditions. Its construction supports efficient chip evacuation and reliable dimensional accuracy when used with appropriate machining parameters.

Suitable for

• Producing internal G 3/4" (BSP parallel) pipe threads in production runs
• Reconditioning or repairing existing internal BSP threads
• Use in CNC tapping heads, automatic tapping machines, and vertical machining centres
• Working with common ferrous and non-ferrous metals where HSSE taps are suitable

Key specifications

• Thread type: G (BSP) parallel internal thread, 3/4" size
• Standards: DIN-5156B thread form and tolerance
• Material: HSSE 800 high-speed steel for enhanced hardness and wear resistance
• Application: machine tap suitable for automated and manual machine tapping operations
• Cutting geometry: designed for reliable chip formation and evacuation in through and blind holes

How to use

Mount the tap in a suitable machine tapping holder or collet ensuring axial alignment with the bore. Select correct spindle speed and feed rate appropriate for the workpiece material and the tap size; follow machining charts for HSSE taps. Apply an appropriate cutting fluid or lubricant to improve surface finish and reduce tool wear. For blind holes use peck tapping cycles or withdraw periodically to clear chips; for through holes maintain consistent feed to allow chips to evacuate. Inspect threads with gauges or mating parts to confirm dimensional accuracy after tapping.

Usage recommendations

Use recommended cutting speeds and feeds for HSSE tools, ensure good chip evacuation, and employ suitable cutting fluid. Replace the tap when wear or damage affects thread quality to maintain consistency in production. For optimal life, avoid excessive radial runout and ensure secure clamping of the workpiece and tooling.
