G Full-Form Thread Mill | Solid Carbide BSPP / PF Thread Milling Cutter

High-precision G Thread Mill (BSPP / PF / ISO 228) made from solid tungsten carbide. Ideal for CNC internal & external thread milling, left & right-hand threads. Multiple coatings available for steel, stainless steel, titanium, and alloys. Boost accuracy and efficiency with our full-form carbide thread milling cutters.

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

MaterialRecommended CoatingBenefits
Copper & AluminumTiB₂ / DLCPrevents built-up edge, smooth chip evacuation
45# Steel / Carbon SteelTiN / TiCNCost-effective, reduces wear
Stainless SteelTiAlN / AlCrNHigh heat resistance, prevents galling
P20 Tool SteelTiAlN / AlTiNLong life in tough tool steels
Cast IronTiN / TiAlNExcellent wear resistance, stable cutting
Titanium AlloysAlTiN / TiAlSiNWithstands high temperatures, prevents chipping
Heat-Resistant AlloysAlCrN / TiAlSiNSuperior oxidation resistance

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:

TypeAdvantagesLimitations
Single-Tooth

– Flexible, can cut multiple thread pitches with one tool

– Ideal for small batches or prototypes

– Slower cutting speed

– Multiple passes needed

Full-Form (Multi-Tooth)

– Much faster, mills the entire thread profile in fewer passes

– Consistent thread quality – Ideal for mass production

– Limited to specific thread pitch

– Higher initial tool cost

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
