Dies are tools used to create external threads on workpieces such as bolts or screws, and while they are not drill bits, they complement taps and drill bits in metalworking. Round dies are circular and designed for forming threads on cylindrical objects, typically used with a die stock for manual threading, while hex dies have a hexagonal shape that provides better grip and control. Both types are commonly made from high-speed steel (HSS) or carbide for durability and hardness. Available in various sizes and thread pitches, dies are versatile tools essential for ensuring precise external threading in a variety of metalworking applications.
