25,147 products
Threading is a machining process in which threads are cut or formed on the external or internal surface of a part so it can be mated with a fastener or another part. Dies and external threading tools create and repair external threads. Taps create and repair internal threads. Threading sets either contain multiple sizes of taps or dies, or they contain a combination of different types of threading and holemaking tools that can be used together for machining tasks that require multiple operations.
