The Baer Circular Die in high-speed steel (HSS) is a precision external-threading tool designed for professionals and serious hobbyists who need reliable metric fine threads on cylindrical stock. It’s built for general use and tailored for creating durable M58 x 4.0 threads with consistent results.

• Material: High-Speed Steel (HSS) construction delivers strong wear resistance for repeated threading tasks.
• Thread size: Metric external thread M58 x 4.0 ensures compatibility with standard fittings and fasteners.
• Pitch: Fine pitch suitable for precise, snug engagements in mechanical assemblies.
• Thread direction: Right-hand threading for conventional, widely used applications.
• Cutting edges: Precisely ground edges promote clean, accurate thread formation with minimal burrs.
• Compatibility: Designed to be used with a standard die stock or die holder for controlled, smooth rotation.

This circular die enables you to form robust, repeatable external threads on shafts, studs, or other cylindrical parts, making it ideal for repairs, fabrications, and on-site maintenance. The combination of HSS durability and finely ground cutting teeth delivers dependable performance across a range of metals, with clean engagement between the new threads and mating components. Use with proper lubrication and steady, moderate rotation to minimize chip buildup and maximize tool life, and clamp your work securely to ensure precise, repeatable results.
