Inch die G 1/2 HSS – professional tool for pipe threads
Die G 1/2 is a reliable tool for cutting BSPP parallel pipe threads with a 55° thread angle. Made of high-speed steel (HSS), this inch pipe threading die provides precise thread cutting on steel, copper, and brass pipes. Compliance with DIN EN 24231 ensures full compatibility with industrial fittings and hydraulic connectors.
Key advantages of the 1/2 inch die for inch threads
- High-hardness HSS steel – enables machining of materials with tensile strengths up to 800 MPa while retaining sharpness through hundreds of pipe threading cycles
- Pipe thread profile with a 55° angle – provides leak-tight connections with a gasket, ideal for pressure systems
- Universal application – suitable for hydraulic, pneumatic, water supply, and gas systems
- DIN EN 24231 standard – confirms dimensional compliance with international inch thread standards
- Flutes – efficiently evacuate chips, preventing jamming during threading
The 1/2 inch die is used wherever reliable threaded connections are required – from compressed air nipples and installation fittings to industrial machine components. The tool performs exceptionally well with black and galvanized steel pipes and nonferrous metals.
The G 1/2 die is the choice of installation and maintenance professionals who value precise pipe threading that complies with standards. Order now and get a tool that streamlines every project.
Frequently asked questions
The 1/2 inch designation (12.7 mm / 1.27 cm) refers to the nominal pipe size, not the thread diameter. The G 1/2 die has an outside diameter of 20.95 mm because BSP pipe threads are designed for pipes with thicker walls.
The G (BSP) thread is a parallel thread – its diameter remains constant along its entire length. G threaded connections are not self-sealing and require a flat gasket or O-ring.
