The Baer Circular Die in High-Speed Steel (HSS) with UNF Left-Hand threading is a precise external-threading tool designed for general use on cylindrical stock. Built for machinists, hobbyists, and workshop environments, it delivering reliable left-handed threads in the No 10 x 32 size.

• Material: High-Speed Steel (HSS) for durability, wear resistance, and long edge life.
• Thread Type: UNF left-hand threads, 32 TPI, suitable for reverse-thread applications.
• Size: No 10 x 32 designation, a common size for external threading on small-diameter stock.
• Format: Circular die designed to cut external threads evenly around the workpiece circumference.
• Compatibility: Works with standard die stocks or die holders for controlled rotation and consistent cutting.
• Edge Geometry: Precisely ground cutting edges for clean, accurate thread formation and smooth engagement with mating parts.

With this Baer circular die, you can reliably create or repair left-hand threads on round stock, ensuring a secure fit with corresponding fasteners. The HSS construction stands up to repeated use across a range of metals, especially when used with proper cutting fluid and steady, concentric pressure. This tool is ideal for engineers, machinists, and DIY enthusiasts who value consistent thread quality, longevity, and the ability to work with standard No 10 x 32 left-hand specifications in a variety of projects—from quick repairs to prototyping and fabrication tasks.
