Engineered from high-speed steel, these round adjustable dies offer a perfect balance of hardness and toughness for superior wear resistance. Ideal for creating new threads or re-threading existing ones, the dual-chamfered design allows for versatile application near shoulders or standard threading. The fine pitch adjustment screw provides precise control by forcing the die sides apart or allowing them to spring together.
