Engineered from high-speed steel, these round adjustable dies offer a superior combination of hardness and toughness for general-purpose threading applications. The dual-chamfered design allows for both standard threading and precision work close to a shoulder. A fine-pitch adjustment screw provides versatile control, allowing the die to expand or spring together for optimal fit.

• Metric standard M4.5 x 0.75 thread size for precision work.
• High-speed steel (HSS) construction provides excellent wear resistance and toughness.
• Dual-sided chamfered design: 2-3 thread chamfer for standard use and 1-1.5 thread chamfer for threading near shoulders.
• Adjustable via fine-pitch screw to force sides apart or spring them together.
• Beveled slot design allows for easy adjustment using machine holder screws.
• 13/16 in. Outer Diameter (O.D.) suitable for various general-purpose applications.
