Product Overview

The G Full-Form Thread Mill is a solid carbide thread milling cutter designed for machining parallel pipe threads with high accuracy and efficiency. Globally, G threads are also referred to as:

• BSPP (British Standard Pipe Parallel)

• PF Thread (Japan JIS Standard)

• ISO 228 Parallel Pipe Thread

Thanks to its full-profile cutting design, this tool can process internal and external threads, in both left-hand and right-hand directions, with consistent precision. It is a reliable solution for industries that require tight tolerance pipe connections such as aerospace, automotive, oil & gas, hydraulics, and general machinery.

Why Choose a G Full-Form Thread Mill?

• Universal compatibility with G / BSPP / PF / ISO 228 standards

• Solid tungsten carbide for durability and long tool life

• Full-form geometry for one-pass threading with superior accuracy

• CNC optimized – suitable for high-speed, high-precision machining

• Adaptable to different materials through specialized coatings

• Capable of left-hand, right-hand, internal, and external threads

Material & Coating Recommendations

Choosing the right coating is one of the key factors that influence machining performance, tool life, and surface finish.

Single-Tooth vs. Full-Form Thread Mills

When selecting a thread milling tool, both single-tooth (single point) and full-form thread mills are available:

At our Minnexon, we can supply both single-tooth and full-form thread mills, ensuring you always have the right solution for your production needs.

Applications

The G Full-Form Thread Mill is widely used in:

• Aerospace → hydraulic fittings, fuel systems

• Automotive → engine and transmission components

• Oil & Gas → threaded pipe joints, valves

• General Engineering → machinery, pumps, pneumatics
