Using this Baer Circular Die delivers consistently formed 8 UN external threads on 1 3/8" diameter shafts, improving fit with nuts, bushings, and other fasteners. The HSS material resists wear in typical metalworking environments, providing reliable performance across steel, aluminum, and other common substrates. The precisely ground cutting edges minimize chatter and rework, while working with a standard die stock makes threading operations efficient and predictable. This tool is well-suited for repairs, prototype fabrication, and routine maintenance projects in professional shops and serious hobby setups alike.
