Usable Cutting Edge Width of Wiper Inserts

The width of the wiper insert itself is 5.5mm, however the actual functioning cutting edge width after installation to the body is 4.5mm, as shown in the diagram.
With one wiper insert, it is possible to machine up to fr=4mm feed per revolution. When exceeding fr=4mm, use two or more wiper inserts. Note that there is a possibility to exceed fr=4mm when using a holder with more than 24 inserts.
