    Our range of thread cutting dies includes high-precision die tools and die sets available in both metric and imperial thread forms. Designed for use in workshops, engineering and fabrication environments, these dies cut and restore external threads on round stock such as threaded rod, studs and shafts.

    We stock a variety of die types including hexagon body dies, round split dies and adjustable dies in common sizes to meet the needs of trade professionals, engineers and hobbyists. Whether you’re repairing damaged threads or cutting new threads, our dies provide accurate and reliable performance.
