Split dies, often referred to as circular split dies or button dies, are essential tools for any workshop focused on precision metalwork. These High-Speed Steel (HSS) dies are specifically designed to cut or clean external threads on bolts, studs, and rods. The split feature is crucial; it allows for slight adjustments via a screw in the die stock, giving you the flexibility to achieve a perfect fit or to compensate for slight variations in material diameter.
In this collection, you will find a range of BSW (British Standard Whitworth) split dies in various outer diameters, from 1 inch up to 2 inches. Using HSS ensures that these tools maintain a sharp cutting edge even under the heat and friction of repetitive use, making them far superior to carbon steel alternatives for professional applications. Whether you are restoring a classic vehicle or working on heavy industrial machinery, having the right die ensures a clean, accurate thread every time.
At Duchy Fasteners, we understand that downtime is costly. That is why we stock a wide variety of sizes ready for immediate dispatch across the UK. By choosing our HSS split dies, you are investing in longevity and precision, backed by competitive trade pricing and reliable technical support for all your threading needs.
