The largest possible nose angle should be selected to provide insert strength and reliability, however, this has to be balanced against the cut varia-

tion need to be performed.
5º & 7º A large nose angle is strong, but requires more machine power and has a higher tendency for vibration.

A small nose angle is weaker and has a small cutting edge engagement, both of which can make it more sensitive to the heat effects.
