Crafted from high-speed steel, these round adjustable dies offer 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 open ends. The fine pitch adjustment screw ensures precise control by allowing the die to expand or spring together as needed.
