Baer Circular Die HSS – Metric Fine, Left-Hand (M20 x 1.5) is a precision external threading tool designed for general metalworking. Built from high-speed steel, this circular die delivers clean, accurate threads on cylindrical workpieces when used with a standard die stock.

• Material: High-speed steel (HSS) construction for durability and wear resistance in everyday threading tasks.
• Thread size and hand: M20 x 1.5 metric fine pitch with left-hand threading capability for specialized assemblies.
• Cutting edges: Precisely ground cutting faces to ensure smooth engagement and accurate thread formation.
• Format and compatibility: Circular die designed for use with a die stock or die holder for controlled rotation and consistent cuts.
• Application: Ideal for general-use external threading on metal rods, shafts, or cylindrical components in workshops and production environments.

This die enables fast, repeatable external threads with tight tolerances, supporting reliable part mating and easier assembly. The robust HSS construction and careful edge grinding reduce tool wear and prolong die life, making it suitable for prototyping, repairs, and small-to-medium production runs. The left-hand M20 x 1.5 threading is particularly valuable in applications requiring reverse-thread engagement to prevent loosening in critical connections.
