PRODUCT DETAILS
The G55 Series Single Tooth Solid Carbide Thread Mill is designed for machining British Standard Pipe Parallel (G/BSPP) and Whitworth 55° thread forms.
Featuring a single-tooth universal cutting profile, it offers exceptional flexibility for threading operations across different thread sizes, pitches, and materials.
This series is suitable for machining both right-hand and left-hand threads, as well as G55, BSW, BSP, and nut threads, reducing the need for multiple tool variations.
Manufactured from ultra-fine grain carbide, it delivers outstanding wear resistance, cutting precision, and long tool life, even under continuous CNC operation.
Ideal for precision machining, pipe fittings, hydraulic systems, and general mechanical parts, this thread mill is a cost-effective and reliable solution for international manufacturers seeking consistent quality and performance.
55° Whitworth Thread Profile
Designed for British standard (G/BSP/BSW) threads with a 55° tooth angle — ensures high compatibility with UK and Commonwealth standards.
Wide Application Range
Capable of threading various diameters and pitches with a single tool, increasing versatility and reducing tool inventory.
Single Tooth Design for Maximum Flexibility
Supports both right-hand and left-hand threads and can machine blind holes, through holes, and nuts efficiently.
Precision Machining Performance
CNC ground geometry ensures high thread accuracy, smooth surface finish, and stable cutting behavior.
Solid Carbide Construction
Made from micro-grain tungsten carbide for superior hardness, wear resistance, and tool stability during high-speed machining.
Hydraulic & pneumatic fittings
Pipe thread and nut manufacturing
Precision mechanical components
