Lead Angle of Thread J
Thread's Lead Angle as shown in Fig.1 decides from the Workpiece Diameter. (Pitch Dia.)
“D” and Lead “L” (in case of Single-start Thread, it is the same as Pitch “P”).
Rolling a right-angled Triangle around a Cylinder and the Angle ACB in Fig.2 becomes the Lead Angle .
The Calculation Formula is shown as follows.

tan L nP : Lead Angle D: Pitch Dia. n: Number of Thread (Such as double-start thread) P: Pitch
D D L: Lead (In case of single-start thread, it is equal to P. In case of n-start thread, it is equal to n P.)

Relief Angle of Thread
Against this lead angle, the threading insert requires side relief angle . TNN type threading insert is a negative insert and there is
no relief angle. When installing the insert in the toolholder, the edge inclination angle (Fig.3) is set, and at the same time front
relief angle as well as side relief angle are generated to the insert. Side relief angle is described by the following formula. (Fig.4)

See table 1 for the Side Relief Angle depending on the insert type.
However, the side relief angle is set for 1° in the traveling direction by the toolholder itself, so that the actual side relief angle becomes + 1°.
