Round Threading Dies Threading Tools Alloy High Speed Steel General Thread UN BSP Metric NPT M2 HSS

An HSS die is a cutting tool, often hex-shaped or round, used to cut or clean external threads on bolts, rods, and pipes, or to repair damaged threads, valued for its toughness, hardness, and ability to retain a sharp edge at high temperatures, making it great for maintenance and demanding industrial tasks. 

Key Characteristics

· Material: Made from High-Speed Steel (HSS), an alloy known for superior hardness, wear resistance, and ability to stay sharp during high-speed, high-temperature use.

· Function: Creates or repairs external threads on fasteners and other cylindrical parts.

· Types: Common forms include hex dies (can be held with a simple wrench) and round dies (often adjustable).

· Applications: Ideal for maintenance, repair, and general-purpose threading in workshops and field settings, offering precision and longevity. 

Types of HSS Dies

· Hex Dies: Often used for re-threading bruised or rusty threads, requiring no special holder.

· Round Dies: Available in solid or adjustable (split) versions, providing precise thread cutting. 

Why HSS?

· Toughness & Hardness: Resists chipping and wear, providing durable, long-lasting cutting edges.

· Heat Resistance: Can maintain its temper and cutting ability at elevated temperatures.

· Versatility: Suitable for various materials and demanding applications where tool performance and longevity are critical.
