1/2 inch G HSSE Inox die – professional tool for threading stainless steel
1/2 inch HSSE Inox die is designed for cutting G (BSPP) parallel pipe threads with a 55° thread angle on stainless and acid-resistant steel pipes. Cobalt-alloyed HSSE high-speed steel provides the increased heat resistance required when machining difficult-to-cut materials. DIN EN 24231 confirms manufacturing precision that meets the requirements of the food, chemical, and pharmaceutical industries.
Advantages of the 1/2 inch HSSE Inox die for stainless steel
- HSSE steel with 5% cobalt – maintains cutting edge hardness at the high temperatures generated when machining stainless steel
- Geometry tailored to Inox – optimized rake angle reduces friction and prevents material from adhering to the cutting edges
- Thread major diameter 20.95 mm – complies with the BSP standard for the nominal size of 1/2 inch
- BSPP parallel thread form with a 55° angle – versatile pipe thread for connections with a gasket or O-ring
- Manufactured to DIN EN 24231 – ensures compatibility with fittings used in the food, chemical, and pharmaceutical industries
The 1/2 inch HSSE Inox die is suitable for AISI 304 and 316 stainless steel systems, piping installation in the food industry, and chemical and pharmaceutical plants. This size is among the most popular in sanitary systems where corrosion resistance and ease of cleaning are required.
Choose the 1/2 inch G HSSE Inox die when threading stainless and acid-resistant steel pipes. A professional solution for installers working with difficult-to-cut materials in demanding industrial environments.
Frequently asked questions
The HSSE die contains 5% cobalt, which increases resistance to the high temperatures generated when machining stainless steel. Standard HSS quickly loses its sharpness in contact with Inox, while HSSE maintains hardness and cutting precision.
Yes, the G (BSPP) parallel thread is not self-sealing. Connections require a flat gasket, O-ring, or PTFE Teflon tape regardless of the pipe material and the type of die used.
