Product Overview

The BSPP Spiral Flute Solid Carbide Pipe Tap (also known as PF/G Parallel Pipe Tap) is a premium-grade threading tool designed to cut British Standard Pipe Parallel (G-thread) internal threads in blind or semi-blind holes. Featuring a spiral flute geometry, this tap ensures smooth chip evacuation and reduced cutting resistance, especially in ductile and sticky materials like aluminum, brass, and stainless steel.

Crafted from ultra-fine grain solid tungsten carbide, this tool delivers exceptional hardness, wear resistance, and thread accuracy, making it ideal for precision machining, automated tapping systems, and CNC applications where reliability and consistency are critical.

Key Features

• Thread Standard: BSPP / PF / G (Parallel Pipe, 55° Whitworth profile)

• Spiral Flute Design: Ideal for blind holes and improves chip clearance

• Solid Carbide Construction: Maximum durability for high-volume and abrasive conditions

• Clean, Accurate Threads: Ensures optimal sealing with gaskets or O-rings

• Optimized for CNC & High-Speed Tapping: Suitable for modern machining environments

Applications

• Creating parallel pipe threads in fluid connectors, pneumatic manifolds, low-pressure valves, and brass housings

• Perfect for materials like aluminum alloys, non-ferrous metals, carbon steel, and stainless steel

• Extensively used in HVAC, automotive fittings, water treatment components, and aerospace assemblies

• Compatible with vertical and horizontal CNC tapping centers, as well as automated production lines

Advantages

• Improved chip evacuation in blind holes prevents tool breakage and ensures clean threads

• Leak-free parallel threads for connections using O-rings or flat seals

• Superior tool longevity, even in abrasive or high-temperature conditions

• High RPM compatible for automated tapping systems with rigid tapping capabilities

• Consistent thread quality, ideal for precision or safety-critical assemblies

Usage Recommendations

• Pre-drill using a BSPP-appropriate core hole diameter

• Apply cutting fluid or MQL to enhance tool life and surface quality

• Use in blind holes or soft materials where chip evacuation is crucial

• For deep holes or continuous use, consider coated variants for heat protection
