The Baer Circular Die in HSS for UNC left-hand threads is a precision external-threading tool designed for general use. Built for workshop pros and hobby machinists alike, it delivers reliable performance when forming left-handed threads on cylindrical workpieces.

• Material: High-Speed Steel (HSS) for durability, heat resistance, and long cutting life.
• Thread Size: 3/4" diameter with 10 threads per inch (3/4 x 10 UNC) for common left-hand fasteners.
• Handedness: Left-hand thread capability to produce reverse-threaded components as needed.
• Application: External threading on cylindrical parts, suitable for a wide range of metals with proper lubrication.
• Compatibility: Designed to be used with a die holder or die stock for smooth rotation and controlled cutting.
• Cutting Edges: Precisely ground cutting faces to ensure clean, accurate thread formation and smooth engagement with mating parts.

This circular die helps machinists create precise threads quickly, reduce rework, and maintain consistent tolerances across projects. Its durable HSS construction and carefully ground edges make it a dependable choice for repairing, fabricating, or standardizing left-handed threaded components when used with appropriate tooling and lubrication.
