Engineered from high-speed steel, these round adjustable dies provide a perfect balance of hardness and toughness for superior wear resistance. Designed for both creating new threads and re-threading existing ones, the dual-chamfered faces allow for versatile application near shoulders or in open spaces. The fine-pitch adjustment screw ensures precise control by allowing the die to expand or spring together as needed.

• M39 x 1.5 metric standard thread size for precise applications.
• High-speed steel construction offers optimal hardness and toughness for long-lasting wear resistance.
• Dual-sided chamfered design: one side features a 2 to 3 thread chamfer, while the other provides a 1 to 1-1/2 thread chamfer for threading close to shoulders.
• Adjustable via a fine pitch screw to force sides apart or allow them to spring together for custom fit.
• Beveled slot design allows for easy adjustment using machine holder screws.
• Versatile use for both creating new threads and re-threading existing ones.
