Thread Milling Cutters

Thread milling cutters are tools designed to cut threads by milling. Varying thread milling tool or cutters enables the production of threads from internal to external, medium to large sizes. Thread milling is the metalworking operation used to create internal and external threads of different sizes through the circular movement of a rotating tool. The thread pitch is created by the lateral movement in one revolution. Unlike tapping, thread milling is primarily used on larger holes.
