Cutting Data
Definition of rotation and cutting speeds for threading tools.
The table below contains the calculated values of rotation and cutting speeds for threading tools between M 3 and M 42. In most cases these calculations
will serve for workshop use in practice. If interim values should be required, these can be calculated by drawing upon the formulas listed below.
