HSS Dies are precision thread-cutting tools designed for producing accurate external threads on rods, shafts, and fasteners. Manufactured from premium High Speed Steel (HSS), they offer excellent hardness, wear resistance, and heat resistance for reliable threading performance and extended tool life. Suitable for manual and machine threading operations, HSS dies produce clean, precise threads with superior surface finish across a wide range of ferrous and non-ferrous materials. They are available in various thread standards, including Metric, UNC, UNF, BSW, BSP, BSPT, NPT, and other international thread forms.
