M12 (1.75) HSS Metric Course Set of 3 Taps

A set of three taps is used in manual and machine threading to create internal threads in metals and plastics, consisting of a taper tap (first tap) to start the thread, a plug tap (middle tap) to continue and deepen it, and a bottoming tap (third tap) to finish the thread. These taps are found in metalworking, automotive repair, and general DIY projects where new threads need to be cut or damaged threads repaired.
