HSS BSP (British Standard Pipe) Dies are precision threading tools engineered for cutting, repairing, and restoring external BSP pipe threads used extensively in plumbing, fluid transfer, pneumatics, hydraulics, engineering, and general industrial applications. Manufactured from high‑speed steel, these dies deliver exceptional hardness, long‑term wear resistance, and consistently accurate thread profiles—even under demanding workshop conditions.
BSP threads are designed for secure, leak‑resistant sealing in pipe and fitting connections, making accurate thread geometry essential. These HSS dies ensure smooth chip evacuation, reduced cutting resistance, and clean thread finishes across metals such as steel, stainless steel, brass, and aluminium. BSP dies are available in a range of standard pipe sizes and outside diameters to suit various die stocks and machine holders, supporting both workshop‑based and onsite service operations.
They are an essential tool for plumbers, machinists, maintenance engineers, hydraulic technicians, and fabricators who work with British‑standard piping systems.
