HSS, Fractional, Standard 1-1/2" OD
HSS round adjustable threading dies are designed for cutting new external threads or restoring existing threads on bolts, rods, and studs. Manufactured from high-speed steel (HSS), they provide the hardness and wear resistance required for precise and consistent thread cutting in general-purpose applications. The adjustable design allows fine tuning of thread fit, making these dies suitable for both shop use and production environments.
