(EXAMPLE M8 x 1.25 Tap with 65% Thread) = 8 — (65 x 1.25) = 7.45 mm Dia. 147.06 APPLICATION Forming Taps cold form threads in ductile materials such as brass, copper, aluminum and leaded steels as well as series 301 to 347 stainless steels. Thread size can be maintained closely since taps have no cutting edges. Unusually smooth threads can be ...
Tap drill bit diameter [mm] Given diameters determine only output values. Tap drill bit diameter in the case of forming taps depends on: machined material. outline of the thread. depth of the hole. wall thicnkess. necessary internal thread diameter.
