HSS Imperial NS (National Special) Dies are precision threading tools engineered for cutting, restoring, and repairing external threads using less common or specialised imperial thread pitches. Manufactured from high‑speed steel, these dies offer excellent hardness, cutting edge retention, and overall durability—making them ideal for workshop, automotive, engineering, and equipment maintenance environments where specialty imperial threads are required. NS thread dies are used when a non‑standard pitch is needed for specific machinery, legacy equipment, or custom assemblies. With smooth chip‑flow geometry and precision‑ground cutting edges, these dies produce clean, accurate threads even on tougher materials. Their wide range of diameters and OD formats ensures compatibility with standard die stocks and machine holders, making them a reliable solution for both general‑purpose and specialised threading tasks.
