Thread rolling dies are usually made from high-strength materials such as tool steel or carbide, and are designed to withstand the high stresses and abrasive forces that are involved in the thread rolling process. There are several types of thread-rolling dies that are used in thread-rolling machines in the manufacturing of threads. These include:

• Straight dies: These are used to roll threads on straight or cylindrical parts. This is the most basic and the most common type of die found in the industry.

• Taper dies: These are used to roll threads on tapered parts, such as the ends of bolts or screws.

• Form dies: These are used to roll threads with special shapes or profiles, such as square or Acme threads.

• Knurling dies: Apart from general threads being forged into workpieces, Thread Rolling machines are also used to form patterns and grips on cylindrical workpieces. So these dies are used to roll a pattern of raised or indented lines onto a part, typically for the purpose of improving grip or aesthetics.

• Fluting dies: These are used to roll a pattern of shallow grooves onto a part, typically for the purpose of improving grip or aesthetics.

• Specialty dies: There are also a variety of specialized dies that are used for specific types of threads or applications, such as thread rolling dies for rolling threads on thin-walled parts or thread rolling dies for rolling threads on non-ferrous materials.
