This round die stock holder is designed for anyone who regularly cuts external threads and needs a reliable, repeatable grip on their circular thread dies.\u003c\/p\u003e\n\u003cp\u003eEach holder is machined from hardened steel with a smooth-bore round body sized to accept standard circular thread dies. Available in seven body diameters — Ø20mm (~0.79 in), Ø25mm (~0.98 in), Ø30mm (~1.18 in), Ø38mm (~1.50 in), Ø45mm (~1.77 in), Ø55mm (~2.17 in) — each size is matched to a specific thread range from M3 through M26. Retaining screws lock the die firmly in place during operation.\u003c\/p\u003e\n\u003cp\u003eTypical applications include cutting threads on steel rod for custom fasteners, rethreading damaged bolts in automotive repair, and hand-threading pipe fittings or structural components in fabrication work.
