The Baer Circular Die in HSS is a precision threading tool designed for general-use external threads on cylindrical stock. Built for reliability in metalworking and machining tasks, it enables clean, accurate 1/2" x 20 UNF threads with a left-hand orientation.

• Thread Size & Direction: 1/2" x 20 UNF, left-hand threading for applications that require reverse-threaded fasteners.
• Material: High-Speed Steel (HSS) for strong wear resistance and long tool life.
• Design: Circular die with multiple cutting edges to maintain consistent thread form.
• Compatibility: Designed to be used with standard die holders or die stocks for easy rotation and controlled cutting.
• Cutting Edges: Precisely ground to produce clean, true threads that mesh smoothly with mating parts.
• 用途: Suitable for general-use external threading, including repairs and new-threading projects on metal stock.

With this Baer circular die, you get repeatable, accurate threads that minimize finishing work. The durable HSS construction withstands routine shop use, delivering reliable performance over time. The left-hand configuration supports specific assemblies requiring reverse threading, while the UNF pitch ensures a snug fit on fine-threaded connections. Use it with a die stock to leverage smooth rotation and precise control, making it a dependable choice for both professional workshops and serious hobbyists working on threaded hardware.
