Engineered for professional machinists and serious DIYers, the Baer Circular Die HSS is a precision tool designed to cut external NPT threads on cylindrical stock. Built for general-use threading tasks, it pairs with a die stock to deliver controlled, repeatable results for pipe fittings and other threaded connections.

• Material: High-Speed Steel (HSS) for durable, sharp cutting edges and long tool life.
• Thread Type: External NPT threads in the right-hand orientation for standard piping connections.
• Size / Pitch: 1/8 in. NPT, 27 threads per inch (27 TPI).
• Handedness: Right-hand cut for conventional threading applications.
• Compatibility: Designed to work with a die stock or die holder for steady rotation and controlled cutting.
• Edge Geometry: Precisely ground cutting edges to form clean, accurate threads that mate smoothly with fittings.

Using this Baer circular die, you can produce reliable, leak-tight NPT connections on a range of cylindrical parts, from plumbing components to hydraulic housings. The HSS construction resists wear in routine threading tasks, while the precision-ground teeth minimize chatter and rework. Whether building new assemblies or repairing equipment, this tool delivers consistent thread quality, longer service life, and faster setup when paired with a compatible die stock.
