The CLE-LINE 0550 two-piece die features carbon steel construction, delivering unified thread form, adjustability, and easy sharpening for hand threading in steel, cast iron, and aluminum. The two-piece design provides dual cutting edges in each half, with die halves seated in a beveled cap slot and secured by a guide that threads into the underside of the cap. One side offers a 2–3 thread chamfer for standard threading, while the other provides a 1–1½ thread chamfer for threading close to a shoulder. Adjustment is made via set screws at either end of the slot, enabling a wide range of precise sizing control. Compatible with Quick-Set die stocks (styles 0650, 0610, and 0710), this die is available in unified and American National thread forms, with inch sizes offered as complete assemblies or components, and metric sizes available as components only.
