- Material: High-Speed Steel (HSS) cutting body for durability and heat resistance.
- Thread Type: UNC, right-hand thread with No. 4-40 size for common fasteners.
- Cutting Geometry: Precisely ground cutting edges on a circular die to ensure smooth, consistent thread formation.
- Compatibility: Designed to work with standard die stocks or die holders for easy rotation and controlled cutting.
- Durability: Hardened edges and robust construction to withstand daily shop use and multiple passes.
Using this Baer circular die, you can reliably create or repair external threads with repeatable accuracy, reducing the risk of cross-threading and misalignment. The No. 4-40 UNC size covers a widely used fastener specification, making it a practical choice for a broad range of projects—from rebuilding small shafts to fabricating components that require precise thread engagement. The tool’s sharp, ground edges work with your die stock to provide a smooth cutting action, helping you achieve clean threads and dependable fit in fewer passes. Pair it with appropriate lubrication and regular maintenance to extend tool life and maintain threading accuracy over time.
