Turn/mill features use the same tools as the normal milling features, but they are renamed with -rotaryX appended to the name to indicate that it is a powered rotary tool. For example, if a tool called center_4 is selected for a turn/mill center drill operation, the tool is copied and the copy is called center4-rotaryX.
Rotary tools cannot be explicitly created, but if you manually select a tool for a turn/mill operation, it is copied and the copy is designated as a rotary tool.
Rotary tools cannot be used for turning operations.
