what is a forming tap
cold forming taps with their lead crests exactly on pitch. Other forming taps have lead thread cold forming teeth that are. not ground on pitch. These forming taps actually cold-work the. thread twice: (1) to form the in-accurate lead thread and (2) to. move it on pitch. This creates an axial thrust on the tap which. increases tapping torque and reduces tap life. Balax Thredfloers form the thread exactly on pitch the first.
