Chipless Thread Forming Taps
High Speed Steel – Ground Thread
List No. 783
Chipless tapping is a cold forming process accomplished without cutting.
Threads produced are stronger than conventional cut threads because
of the swaging and work hardening effect. This process helps reduce tap
breakage and permits faster tapping speeds. Please specify plug or bottoming chamfer.
