Threading Tools

Hand Tap Sets

Hand tap sets are manual thread-cutting tools typically comprising three stages—taper, plug, and bottoming—to progressively form internal threads and minimize tool breakage. Forged from High-Speed Steel (HSS) or HSS-E, the multi-stage process distributes cutting torque, ensuring precise thread geometry and alignment without machine assistance. They are heavily utilized for low-volume production, field repairs, and chasing damaged threads in heavy machinery and automotive maintenance.
